Help with bluetooth! hci_get_route returns ERNODEV

Hi!
I am developing an application which connects a Wiimote to a bluetooth enabled android phone/device.
I did this by interfacing with the native bluez bluetooth library directly, rather than via the Android API. The reason for this is that Android API doesn't support HID devices, which a Wiimote is.
A problem now is that on some devices, mostly those sold by HTC, my app simply doesn't work. After calling the hci_get_route(NULL), this function should return an id of the first bluetooth device available (most likely 0), but instead returns ERNODEV (-1) as if no bluetooth device is available.
I suspect it has something to do with our beloved HTC grossly modifying something in the libbluetooth library to make this fail to work.
Has anyone ever done this kind of bluetooth interfacing?
How could I make this work?
Rooting the phone and replacing a library or two would be fine too.
For a list of working and non-working devices, check out the 2nd post of this thread.

HTC support
I just sent a customer service message to HTC about this issue. I hope they can get back to me with a "we'll work on it" message, or something. I really want this on my incredible. I'm new to coding like this, but could you disguise the Wiimote as another kind of device?

Just a response from someone equally interested in a solution. I'm trying to set up a bluetooth keyboard (Freedom Pro) with my gsm Hero running the 1.5 based MCR 3.2. Available drivers (Freedom's own, BlueInput & KeyPro) should work with 1.5, but HTC devices, especially the Hero, seem to be lacking something that is present in most 1.5 builds.
Investigating, I find the same issue of no route to device, because there is no known device. AIUI when bluetooth is turned on hciattach is used to establish a link to the hardware. At that point an hciconfig should list the hci0 device as present but down. However I find this list remains empty at all times.

I found this for keyboards.
Since I can't post the link, it's called "KeyPro for Android"
Google "keypro android" and click the first link.
Maybe that could help. It says it works with any android device above 1.5, however, I did read that some keyboards use a different type of bluetooth profile, SPP rather than HID.
I haven't heard back form HTC yet either.
EDIT: Upon reading your post again, you have tried this. Sorry, my bad.

Thanks for looking though The Freedom Pro is switchable between spp & hid profiles, so I figured I was safe, lol. Not with HTC's butchered 1.5 bt it seems.

Did you ever try to use the most likely id 0 on an HTC device? Even though the call to get the id fails?
Maybe you could use also the Android API to synchronize if a device is present and then use the id that Android API gives you?
Just some thoughts since I would love to see that App running on my Desire with Snesoid

Believe it or not, I actually tried this. Unfortunately, the next command (to bind the bluetooth adapter) also fails, and of course every command after that one because the adapter is not bound.
Thanks for the idea anyway.

usb
does the wii remote have usb connectivity? could it be possible to have the communication pass through that connection rather than bluetooth? one advantage of this would be increased battery life and probably better compatibility across models.
i'm sure some people would prefer bluetooth, but i figure i'll always be using it very close to my phone so i can see the screen, so the wired option is actually a bit more attractive (considering battery performance).
i know ps3 has usb connectivity as well, you just might need an adapter (mini to micro).

I'm pretty sure the first answer is no - our wii is round at a friend's atm. However even if it was yes, you'd need more than an adapter. USB operates with one device as master & the other as slave. To allow you to connect slave devices to your phone it would need to be in host mode. Some mobile phone hardware implementations support this, however I don't know of any mainstream Android kernels which do. Even if you workaround that, you're left with the huge issue that slave devices can assume it's safe to draw power from the USB bus which could do nasty things (tm) to a lower power device like a mobile. This can be worked around via a powered hub, but it all gets very messy.
I looked into this a few months ago, hoping I'd be able to use a usb keyboard with my Hero. I ended up with a BT keyboard instead. Of course that doesn't work either but for completely different reasons, as hinted at by this thread. Hopefully a 2.1 ROM will solve that, but that's the subject of numerous other threads.

Uh, just throwing stuff out, what if you have a pc with two bluetooth adapters, it connects to the wii mote, and then broadcasts that in someway the android api can understand?
Also please actually try working on something with a rooted phone, the HTC EVO 4g is rootable, and I will make man love(no homo) if you get it working.
Either one works lol.

Using a PC as a proxy is kind of useless. If you have a wiimote connected to a PC, you might as well play games on the PC itself (there are nes/snes/sega/etc emulators for PCs too).
At this moment, rooting doesn't help with the problem either.

@1 True
@2 That sucks.

Do we think that this will/could be fixed in HTC's Froyo update for 2010 devices? Not looking for definite answers, just a ponderin'.

well if you send the null pairing code to the wiimote from the default bluetooth pairing screen.. it will fail to communicate with the wiimote too

Doesn't it work in stock/vanilla Eclair? I thought the main problem was with Cupcake, though HTC seem to have done weird things to every stock firmware. I read that removing Sense from a 2.1 HTC ROM breaks bluetooth. Go figure. And there was I thinking Sense was a gui enhancement

I contacted HTC about their bluetooth issues and just received this response

I contacted HTC about this issue with my incredible and I basically got the same answer except the guy was more knowledgeable and said that other people were complaining about certain bluetooth issues. I think they know what they did and are waiting to fix it in Froyo to be easy for them. No worries though, should be comin' in a few weeks. I can't freakin' wait. I have soooooooooo much Pokemon and Mario to play.

does anyone know if this works on samsung galaxy s, i dont have my phone yet to test, but as soon as it arrives (sometime next week) i will test this.

All I can say is that my wii controller is working really well on cyanogen on my evolution now!

Desktop/UI via HDMI-Out

One of the biggest features I'm looking for in either the EVO or Streak (still not sure which I'm going with, gotta wait another month for the Streak to come out) is to have the Android desktop/UI/home screen sent out via HDMI. What I would hope to do is:
- be using the phone
- dock it (with HDMI to display)
- have the display show up on the TV (preferably fitting the aspect ratio and resolution of the display, though not necessarily a requirement)
The thought then would be to use a mouse and keyboard via either Bluetooth or USB (in host mode, obviously), and use the phone on the larger display to function basically as a netbook replacement (web browsing, music/videos, light gaming, light office prod. stuff).
I've seen other people on here asking around if it was possible, which it looks like it ISN'T out of the box...but maybe a developer looking for something to do might pick up on this post. You'd make a lot of people very happy!

I am also very interested in this.

So basically something like this?
http://sven.killig.de/android/N1/2.2/usb_host/

I think a good example would be the functionality that matches the current Touch Pro/Fuze TV-Out functionality... Unlike the HDMI output restrictions that are currently on the Evo device, I am able to use the entire OS (Winmo) to select start, programs, play programs, games (Tony Hawk), etc. The TV acts a full clone to what is on the phone screen itself..
I am looking for similar functionality so I can play a movie, nav, on a HDMI connected slate while the Evo is out of site (examples - vehicle screens, portable screens ). Obviously there would no input commands from the screen attached device, but a bluetooth air mouse could help out with that.

Yeah... would be nice, imagine HID bluetooth devices(wii mote controller) hook the phone to a tv, and play some classic games...
RIGHT ON

Yes, as far as input goes, but it would also need software (or a core OS update?) to push the display out via HDMI, at the same time.

I was really interested in this as a possibility, and certainly took notice of the nexus one with host USB capability. Bear in mind the Nexus One was not pushing the device's display out, it was running an X server, but still a neat idea.
I know that currently only the HTC software can push anything out of the HDMI port, but I expect it is simply a matter of applications knowing to take advantage of it, probably not even drivers.
A quick google of htc evo hdmi API gets you sprints android development site, which says the guide includes info on how your applications can take advantage of the HDMI port. I haven't messed with the android API much yet, but the only issue would be for someone to write an application that can grab the entire display, and then push it out to the port via the API.

Only thing I'd worry about there is that it isn't actually "grabbing" the screen (as in screen captures, polling it for changes, etc) because that could absolutely kill performance. That's why I wonder if it wouldn't require driver access or update, in order to actually "push" the display out the HDMI port (note: I'm not a developer, so I can only do my best to keep up with what potential issues might be. )

Any update on this?
I noticed if you read further down on the USB Host Mode page, there's info on a USB TV driver (TV IN sadly), an X11 driver (not sure which way they mean), and also DisplayLink although I think that is some kind of device you need to buy. If I could X11 remote host my Android that would be PIMP but I doubt I'll get that lucky!
I desperately want to do this myself (TV OUT from Android), whether it be HDMI or USB or whatever. I need to output the OS and apps (for demo purposes).

i was thinking the same, somewhere along the lines of PdaReach for palm devices. but the monitor being an actual TV for entertainment purposes. ...trying to get my extra ten dollar fee to use. so if and when netflix decides to make a platform for android devices we could hence watch movies on our televisions via our phones streaming to the TV

The framebuffer is unprotected on stock Evo's & rooted Evo's alike, so if you just grabbed every frame as it went through the framebuffer and outputted it to the display, it could be done easily on any Evo. That is unless HTC plugged the unprotected framebuffer bug on a new update.
In any case, it wouldn't be that hard, it'd hurt performance a little, but I don't know for sure. An app wouldn't be that hard to make, think a high speed screenshot app, talk to the devs of ShootMe about how they grab from the framebuffer.

That won't work. It's already in the Evo developer docs as posted by the person above me. All it does is take any VideoView object in any app and broadcast it over HDMI unless you specifically tell it not to in the application manifest.
There is no way to run that as a service. As of yet I've tried the following:
Copy frames via CLI from /dev/graphics/fb0 (the main screen framebuffer) to /dev/graphics/fb1 (the HDMI framebuffer) to see if it is possible to work it like that. It isn't.
Symlink the two framebuffers so in theory whatever happens to one, should happen to the other. It doesn't work either. It does do something since it breaks HDMI output, but it doesn't display the screen. This could be because the resolution doesn't match one of the TVs supported resolutions.
I'm still going to try a custom kernel once I get my build environment set up (hopefully tomorrow) with a few changes, but I can't promise anything. Anything more complicated than Java is a little over my head, but I can do a little.
I'll keep you posted.

[BOUNTY] "We" Hire a Developer for Bluetooth Wii/Ps3 controller app!

So I was digging through the source code Samsung released for the Galaxy S, and in the eclair zip I started digging through the bluetooth folder and came across multiple files that look like they support pairing a PS3 controller...
when you have functions like
Code:
static int ps3remote_decode
it gets you thinking lol.
So anyone with some experience with this device let me know if its even possible to pair with a sixaxis or dual shock 3, and if you have some experience with source take a look at the attached zip, its the
external/bluetooth/bluez/input folders contents
Main references are in sixpair.c which is the actual pairing application I'd assume, and in fakehid.c, and fakehid.h

I wouldn't jump to conclusions to fast. Because of the DLNA support I think they are talking about the PS3 remote control not the controller.
I'm sure the support can be added but it probably would take a little bit of hacking.

you know I'm not so sure now. I just looked in the main branch of Froyo source, and sure enough those files are still there. So I don't think it has anything to do with DLNA. Plus if it did, why would it have anything in there having to do with pairing a PS3 controller and decoding the button presses of one and assigning them to keyboard presses. Has absolutely nothing to do with DLNA

As I said its probably referencing the video playback remote control and not the game controller. Both use Bluetooth

and like I said Sixpair.c specifically Mentions Dualshock 3, so I don't think thats what it's mentioning. Especially considering theres button mapping for L3 and R3 which isnt on the bluetooth remote for PS3

You didn't mention that in your first post. You just said can it be configured with a dual shock or sixaxis controller.

sixpair is a helper to pair with a Sony DS3/Sixaxis bluetooth controller.
it is part of the bluetooth protocol stack for Linux, called Bluez.
they used this helper to get the DS3/6axis to work on the Nokia N900.

So it is possible!!!
this is just amazing if it could do that

Wii/PS3 bluetooth controller problem?
All reports of the WiiMoteController say it doesnt work on the Galaxy S.
Do we know why exactly? the author comments on this for the HTC devices. does the galaxy S share the same problem?
"on some devices, mostly HTC, the application starts searching and then stops immediately with the "Error no -1" message, even if the bluetooth is on. Most likely a fault from HTC and unfixible for now. See this thread for technical info. If you're a developer and have solved this kind of issue before, please tell how! A lot of Android users will be very grateful
(finding the wiimote with the phone is not the actuall issue here, but rather the lack of support for the low-level connectivity with the phone's bluetooth. BAD, BAD HTC! Go stand in the corner!)"
is this a quick fix or something deeper?

With regards to the htc sense affecting the wii controller app - I believe theres a bug with the htc bluetooth stack that returns null when pairing devices this stops code beyond this from executing, or something along those lines.
The way around this is to use a ROM, without Htc sense like OpenDesire, which has been tested on these forums.
Still as yet i don't know what the reason is for the Samsung Galaxy S, if its a similar bluetooth issue, but i'm as eager as you to find out because it would make the perfect emulation device with that screen!

I would LOOOVE a psx emulator with a working PS3 controler.. Maybe with froyo (also around the corner) we get 2 flies at once.. Faster emulator and (support for) a real controler (WOW!)

its pretty much ready just waiting for a few tweaks from the emulator android guy. only the dev's word on that though, but its the same guys who did the iphone emulators zottd (or something) and the guy who did the android emulators. should be a good product.
and yes wtb froyo and increased bluetooth support for controllers
they also mention about the PS3 controller and there may be a way to sync it but you need to sync with a PC first...not sure on the reasoning behind that.

Man, that would be sweet. One thing about the galaxy s is that it has a great screen and powerful GPU but the only controls are the ones on the screen that are difficult to play with. I know this is of topic but does anyone know if the wiimote will ever be compadable with the galaxy s. I have tried it and does not work as of now.

It will work when the cyanogenmod ROM comes out, they have announced they are supporting the Galaxys S, should only be a matter of time.

It's just to use the ps3 controller to control your games. You can do the same with the WiiMote, you can even use it in the NES and SNES emulators.

I got mine today. I ordered it over a week ago. Weird because I didn't get my shipping information until last night, and when I tracked it, it was already out for delivery.
My Measy Air Mouse R11 is screwed though I think. It keeps sliding to the left hand side. I even tried on my PC and it does the same thing. I've tried to resync it and screw with it, but it keeps moving. Very hard to use a mouse that doesn't stay still. The MK808 is fun. I just got it tonight. I haven't had the time to get really crazy with it. Seems to run ok and would be far more enjoyable with a good input device.

Ordered mine today (only $60), if it really works as reviews say, it's quite a bargain

Do you still have problems with the rc11 or are they solved ?

I fixed my Measy Air Mouse R11.
To reset the Gyros, you lay it flat and press and hold LEFT ARROW + G for a few seconds... making sure it is flat. Now it works great.
I'm having some weird issues with some misbehaving apps. Root explorer started freaking out. And now my FPse won't use OpenGL for the life of me. I'm interested in trying the CM10 build for it but the operation requirements are bland. Supposedly it requires CWM recovery, which is supplied but doesn't give specifics how or what order or process to get it done.
I have to say that it is a fun unit to work with and chews through FPse roms. I'm surprised how well it runs for a chinese chipset.
Flashing is a bit of a chore and instructions aren't very clear, so I'll post them here:
With the unit OFF:
Insert a paper clip into the reset hole and press it in and HOLD IT down.
Awkwardly insert the MicroUSB-PC cable into the OTG. This will power the unit and it should boot into Flash mode given you've held the paperclip down properly.

Trying to install eGalax Touch Screen linux driver
I'm trying to install the eGalax Touch Screen driver for Linux 2.6 that came with my liliput 7 inch touch screen. The touch screen is for use in my car. Using the mk802 II or ug808 to replace my audio system. I just need to get the driver installed. The driver installation script is looking for the locations "usr/local" and "usr/bin", but the only "usr" directory I can find is in "system/usr"... I'm not sure if I should use that location and create the local and bin directories there or not. But when I created the usr/local and usr/bin at the same level as system (which is in the "mnt" directory which is also at the same level as "root" directory (btw, I cannot find a "home" directory), the install seemed to work fine using Better Terminal Pro android app with the bash shell. However, when I restarted the device, the "usr" directory that I create was gone, so the driver install was wiped apparently, and the usb HDMI touch screen still does not work... I can post the bash script if that helps. This is the last thing I need to get this to work, then I can have a full Android ICS system in my car. Thanks in advance.
FYI The HDMI works great to view and use a usb mouse or the RII keyboard. they work great. It's just the touch screen input does not work. It used to when I first turned on the device with the touch screen on, but the x-y coordinates were reversed, hence attempting to install the driver. I have ICS compiled from source and may attempt to add the drivers into it and create an img to them load on the mk802 II, but I fear that I'll loose any proprietary hardware drivers that came with the mk802 II.
I also wanted to make a img backup using ROM Manager, but ClockworkMod is not available for the MK802 II. ANy leads on this would help. Been researching and testing this for a month now.

Ordered on the 26th for 65$ (actually cost £42 through paypal),
they shipped on the 29th (tracking never worked).
And it arrived on the 6th. So quicker than expected.
I've applied the firmware update which was a slightly newer build of 4.1. Mentioned in both these places (applied the tweaked one from deadhp1 for the play store location fix in case needed)

It now seems to play any avi / mkv / mp4 i've given it (usually on a usb stick or micro SD). It happily plays avi's over the network (using ES file explorer).
Its definitely better than the out of sync UG802 which wasn't quite right and the power lead came out too easily.
I use the custom stock video app (seems to come with most of the RockChip devices) and MX player (it looks a lot nicer)

I was looking for a device like this one and the reviews are really helpful

Anyone know of GPS that works with these?

Anyone know of GPS (USB or embedded) that works with these? Thanks for your help.

So confused... it's a USB drive that turns a TV into an Android PC? Does the TV require any special functionality to allow for that?

It is a mini PC that has HDMI output. Your TV must have a vacant HDMI input so you can plug the mini PC into it. My TV supports 1080p. And so I can set the output resolution on the mini PC to 1080p. But it also could be set to 720p as well. These don't come with any display so you have to plug it in to your TV or a monitor that supports HDMI. The audio is pushed through the HDMI as well. To control it you can use a USB mouse and/or USB keyboard. Your cheap wireless mouse will work but the USB ports do not have power to them so I've had to use a powered USB hub to make my wireless keyboard work further than a foot away from the USB dongle for the keyboard. The hub also allows you to plug in other devices like a USB camera. But the ones that work are somewhat limited , be aware. Does that help you understand it?

I'm trying to install the eGalax Touch Screen driver for Linux 2.6 that came with my liliput 7 inch touch screen. The touch screen is for use in my car. Using the mk802 II or ug808 to replace my audio system. I just need to get the driver installed. The driver installation script is looking for the locations "usr/local" and "usr/bin", but the only "usr" directory I can find is in "system/usr"... I'm not sure if I should use that location and create the local and bin directories there or not. But when I created the usr/local and usr/bin at the same level as system (which is in the "mnt" directory which is also at the same level as "root" directory (btw, I cannot find a "home" directory), the install seemed to work fine using Better Terminal Pro android app with the bash shell. However, when I restarted the device, the "usr" directory that I create was gone, so the driver install was wiped apparently, and the usb HDMI touch screen still does not work... I can post the bash script if that helps. This is the last thing I need to get this to work, then I can have a full Android ICS system in my car. Thanks in advance.

probably you will need the kernel sources. also, you need root access. that error (directories that get lost after reboot) might be due to yo need to remount the /system partition in rw mode (by default is ro) and perhaps you will neet to do some symlinks on /bin to /system/xbin.
other thing you..must get in considwration is that android is different from linux.. and that you might need to compile the kernel module, such thiing im not sure that is posible from within the device itself...
or.. i just might be way off track, in which case jyst dismiss my answer

just so you know it doesn't have built in bluetooth.

if you need bluetooth google for imito mx1. this one seems to be the best mk808 model so far. i got mine last month but haven't tried bluetooth yet. antutu gives a score around 6500. it's a nice toy to play with on bigscreen tvs.

I read up on this one. Good vid review at http://youtu.be/X8pozwuAq7w
Anyone know the spec diff between this and the MX2?
and is geekbuying the best seller for this device or ???

---------- Post added at 11:31 AM ---------- Previous post was at 11:24 AM ----------
can anyone comment on this non-support of XBMC for Rockchip? and if not Rockchip, which stick-PC gets it right?
one comment also that I would like more info on is that both iMITO units underperform compared to MK808
"Lack of XBMC support for HD hardware acceleration is a major issue that Rockchip needs to address if they want to keep selling SoC chips to the Stick PC mfgrs. Stick PC makers need 2 take action on this as well and if Rockchip won't play ball, they need to consider alternative SoC. We need more processing power anyway to get close to current smart-phone level and play the latest 3D games."

bluetooth completely borked. fix it google!

I've been trying to get a BT mouse to work on my nexus 4.
i've now tried 2 different models, without success.
both are recognized, both pair and then both completely fail to work.
to add insult to injury, i tried one of those mice on a friend's samsung google nexus today -- also running jellybean -- and it worked perfectly.
could anybody running a BT mouse successfully SINCE THE LAST UPDATE (4.2.1) let me know what make/model they have?
EDIT: maybe they heard me ...

i understand your frustration, but just one question.. why are you using a bluetooth mouse on a phone? tablet, understandable but phone?!

take a nexus 4 + slimport adaptor + BT mouse + BT keyboard,
add an lcd TV with hdmi input (now common in hotels etc.),
and you have:
- a portable PC
- a decent home media centre (with armchair remote input)
- possibly a productivity tool for editing text/ photos etc. for which a touchscreen is too inprecise an input device.
understand now?

Instead of doing all that why wouldn't you just go wireless display and then use the phone as the remote at the sametime? Wouldn't that make more sense?
And AFAIK, bluetooth input devices weren't supported?

sorry, i typically use a laptop for those things. It would make a lot more sense btw. You can also use your phone as a bluetooth mouse/keyboard if you have a laptop that connects to a tv.

a/ i haven't a clue what "go wireless display" means.
b/ "use the phone as a remote" ... for what exactly? and how does that help me?
c/ where has google stated that "bluetooth input devices weren't supported"? that's nonsense.
re-read my previous post and try to get your head around what i am trying to achieve.

Wow, you are quite "the absurd man". If you're trying to find help in a forum, it's best if you be a bit nicer. We're both trying to give you better alternatives to what you're trying to accomplish. To answer your questions...
A/wireless display technology is built in with the n4 and jelly bean and it's not yet widely available to most tv's yet but achievable with adapters.
B/so you don't have to carry around a Bluetooth mouse and keyboard. It helps you with 2 less things you carry (unless you're using a combo).
C/this one I can't back him cause I thought it is supported. Maybe it is broken, but I don't use it so I wouldn't know

... perhaps more sense to you, not me.
i don't want to carry a laptop around when i already have a computer in my pocket.
and i'm not happy with touch input devices as they are too slow and lack the precision needed for heavy editing.
these are my (not i.m.o. unreasonable) requirements of the nexus 4.

getting the display to the TV is no problem -- i already have a slimport adaptor! why would i want to max out my wifi for that? it's bananas!
and i've already said that i don't want to use touch input as it's too slow and inprecise for my purposes.
my portable (igo stowaway) keyboard and notebook BT mouse are tiny (and inexpensive).
sorry to seem abrasive but you are not getting what i'm trying to achieve here.

i've heard other people making the tablet/ phone distinction before and i'm not sure it's a valid one. the nexus 4 surely IS a tablet, albeit with a smaller physical (not resolution) screen. what else distinguishes a tablet? i use my N4 in exactly the same way i used my asus transformer and playbook.

In your first post you didn't clarify that you were going to hook it up to a tv, so I assume that you were planning to connect a Bluetooth mouse and keyboard to your n4 and try to work from it's bit-smaller-than 5" display, which is highly unproductive.
N4 is technically a phone, not a tablet, by definition and specifications. I shouldn't have to explain the differences between a phone and a tablet (I'm sure there's a thread with detailed explanations)... just because it's running the same os doesn't mean it has the same hardware classification.
I understand that you want your N4 to replace your computer and the technology is very close, but not quite there yet... For simple tasks, it's good, but for anything editing, a laptop computer is highly more productive than a phone. Imagine you're doing something and you constantly receive phone calls and text messages.
Anyways, I will test this later when I get home and see if it's really broken. I know my Bluetooth moga game controller works just fine so I don't know why your mouse wouldn't.

i'd appreciate that, thanks.
my BT keyboard works fine, but no mouse that i've tried.

Bluetooth is pretty much borked in all versions of Jellybean for all devices. Some things work and some things don't its pretty hit or miss. Version 4.2.1 added some drivers for game controllers but not much else so that's probably why those work and things like mice don't. There is supposed to be another fix coming in the next version but all that's known to be in there for sure is a fix for A2DP streaming.

however, the (jellybean) samsung google nexus has no problem running a BT mouse, as i saw today.
i'd like to raise awareness of this problem with the N4 and get some more response from users, which has so far been sparse, probably because (as other posters in this thread have indicated) few see the need for a mouse.
for instance, somebody reported on another thread that they had been able to make a microsoft 5000 notebook mouse work. can anybody corroborate that?
i'm reluctant to shell out for yet another mouse considering that i'm currently holding 2 non-functioning ones.

not sure how much good it's going to do but i've opened an issue (#43918 Nexus 4 -- bluetooth mouse not working.) with the android development project:
https://code.google.com/p/android/issues/detail?id=43918&thanks=43918&ts=1359688071#makechanges
"bluetooth mouse not working on nexus 4 (jellybean 4.2.1)
i've tried 2 different models of bluetooth mouse. both are detected and pair, and are recognized in settings as input divices, but i get no on-screen cursor nor any mouse/ button input registed by the device. nothing.
the same mice work properly on a samsung google nexus."

i've had one response to my issue at google already.
could anybody else who is having this problem please add to that thread also?
https://code.google.com/p/android/issues/detail?id=43918&thanks=43918&ts=1359688071#makechanges
meanwhile i'm awaiting delivery of a microsoft notebook 5000 BT mouse which has been reported to work by another poster. i'll report back on that when it arrives

UPDATE:
at last i've found a mouse that works!
the microsoft bluetooth notebook 5000
