Hi first thing I will say is this is not for XDA but for SPV E200. I am aware this is an XDA forum but after seeing some of the things you guys have been able to do with the XDA ROM/OS I thought I would ask if anyone in here could help with this problem due to the similarity of the devices and the fact that they are made by the same company, HTC.
I have posted this originally in a Modaco forum for Smarphones but noone is technically capable enough to help.
If you could read the link below and reply if you think you are up to the challenge of hacking the SPV to get rid of this extremely annoying "complete lack of bluetooth range in headset mode" problem.

Come on there must be someone out there?
Advice
Hi,
It is really hard to come up with something because I have no idea about your device
Try to contact your brand reseller and ask him for system updates, or check forums that are dedicated to your device for such updates. System updates can usually resolve such issues in 70% of cases
Try to minimize 3rd party software usage and check your devices again
Try Pocket Bluetooth Tools (both versions; check for url at xda-dev frontpage)
Try to change your coat/case/cover because it might have BT radio frequency reducing effect
The hardware is HTC, just like the XDA.
The reseller is Orange and they are bringing out the C500 to replace it as they have given up on the E200.
Orange have no intention on bringing out any more fixes for the unit.
All I need is for the power to be increased in the bluetooth transmitter when it is in headset mode.
Finding right upgrade
What I propose to you is to check different upgrades:
http://www.msmobiles.com/news.php/2210.html
http://web.orange.co.uk/yourphone/spv2/promo.html?id=SPVE200_ROMCodeUpgrade
http://www.mtekk.com.au/browse/page657.html
... all of them claim about BT functionality improvements
They all have better functionality as in they work with more headsets, but none of them increases the range.
I am on the latest Orange E200 UK release currently. I have scoured the web for a fix and found nothing, hence my last ditch attempt to see if someone can hacl the phone.
What about the rest E200 users

And what about other e200 users? Do they have the same problem?
You don't need any hack. If you use your BT headset in BT discoverable mode, then BT radio works at a maximum transmission rate, if in usual BT on mode, then BT transmission is adjusted to the environment (bonded devices)
hi guys, i couldnt help noticing that when i previously used nokia 6600 (symbian s60) they had few 3rd party that is able to make use of their audio mechanism during callls. for example, one software can make selected background noise for opposite callers so they think that u are at a train station for example when infact u r silently at home. another software is an on board answering machine, which after the phone rang for a few times it answer the fonecall with your automated recorded voice and recorded a msg left by the caller on the fone. this is convenient for us so we dont need to call back our voicemail and reduce cost as well as some telco charge to use their voicemail service. im surprised these kind of software have not came out for our windows mobile device when its already available for symbian. im sure it shouldnt be that hard to make it. any coder expert wanna give it a go??
cutefox, what kind of searches have you made for this software on this board? Did you have much luck?
V
i already tried commercial such as handango and pocket gear.. even freeware sites also no luck.. jus dun understand why no 1 made one yet.. shouldnt b too hard to make one.. it will be a big market to sell such a software for our ppc phone device now that more devices is coming out..
Cutefox: have you tried searching this board? Let me save you the effort, but it'll be a good idea next time. It's not generally considered possible, at least on WM2003 devices because of both hardware and software limitations. It's not that no one has thought of it before: someone seems to think of it approximately every two days... but there are many many threads on this issue.

Look at what I said here...
http://forum.xda-developers.com/viewtopic.php?t=9761
That sums up why we can't do it using the api's available to us now. The funny thing is the way bluetooth sends the audio stream to a headset. Obviously the data is getting there somehow but I suspect it is not (directly) via windows. Dose anyone know if the radio hardware for bluetooth is connected to the radio hardware for the phone? My guess is that if you could write a program that windows "sees" as a headset then you could get the audio that way. But thats a problem in itself.
I would love this kind of program myself. How is it that such usefull devices with so many capeabilities can be kept secret from us. We can't use the camera, we can't get the cell id on towers, we can't programatically controll the partnerships in blutooth, we cant get the audio stream of our own phone, the events on some ppc's that control brightness are secret..... the list goes on. This kind of #@!!$$ is going to hurt the future of these devices which I otherwise love.
OdeeanRDeathshead: I had read your previous posts, and as ever, very interesting and informative reading. I had the same idea regarding a "dummy" bluetooth device a while back, but mamaich put me in my place!

thanks vijay555, thats what I have suspected about the hardware. What I want to do is a bit different. The bluetooth can communicate to many devices at once. If your program could appear to be a headset to the os, then the phone bluetooth hardware could transmit the audio to the headset at the same time your program uses bluetooth to receive it. Kind of like a loop out of the box to bridge the lack of functionality. This shifts the problem to how dose a hardware bluetooth headset communicate. Emulate this and we are on a winner. I don't think I have the willingness to pull my devices appart. I also do not have the money for some of the hardware (eg good digital oscilliscope) that I would need to measure whats going on. I did read that microsoft are about to expose some new api to allow control over the pairing process (but not the audio stream). I hope that we get some soon.
Is there going to be any new (for 2005) free development tools like the evc versions used today?
OdeeanRDeathshead: re eVC, I don't think so. The "express editions" are free, but they specifically omit the functionality to develop "mobile solutions".
Re the loop back. That's a good idea. I think mamaich is our best bet on schematics, I think that would be very helpful. As you "rave", it's mindboggling that Microsoft still haven't revealed or implemented a way to interact with the audio channels. It must have been one of the first things one could imagine doing once you develop a PDA with a phone stuck on the back of it.
Any idea if the bluetooth stacks could support transmitting and receiving simultaneously in this manner? I know some of the boys are working on alternative bluetooth support for the stereo headset profiles, so they might be able to shed some light on the issues involved. I guess the processor overhead could be hefty, but for the benefit it would be beneficial.

Hello.
Before you tell me... I already searched the forum and I can see many posts about the problems with BlueTooth in the Hero based ROM's, but none of these posts I read (I could have missed some, of course) say what the problems are exactly, so I don't know if it can be a problem for me or not.
The only things that I need from BT are connection to the Parrot CK3000 handsfree on my car, and to send/receive files over BT. Ocassionally I will use the Magic as a 3G modem, but I can do it through USB if not working through BT.
Are these BT features affected by these BT problems on Hero based ROM's?
Thanks in advance.
Not sure if this applies to all hero roms but in the 'jacxheroskiv' rom the problem is a missing shared object (just a missing file in the filesystem)
http://forum.xda-developers.com/showpost.php?p=4479554&postcount=96
Hi There
At the moment Bluetooth is problematic on all hero roms for the sapphire or otherwise. Audio head sets (wireless headphones) seem to work ok but everything else doesn't. So unfortunately your car kit won't work. (I have the same one, it pairs but the audio is garbled) File sharing on the other hand is a problem for all the androids so far (There is an app on the market that provides the functionality but it's not as elegant as it could be) so don't expect that to work on hero roms. I haven't tried Bluetooth tethering because WiFi tether works so well. Perhaps someone else could comment.
Now for the difficult part...
So far as I can tell a willing developer, correct me if I'm wrong, could make the Bluetooth work if the source code for the hero was made available (should be available in a few months if the recent release of the sapphires source code is anything to go by) There seem to be quite a number of people who need this functionality so I'm sure one of the rom cookers will get to it but unfortunately there is no way to know exactly when. For this reason I've decided to stick to the ion roms for now. In any event, Touchflo/Sense UI will be made officially available for the magics in due course...for a price of course
On another note any support financial or otherwise is greatly appreciated by the developers so if you want to encourage a particular functionality a few bucks and a friendly message will go a long way. Please remember though that the developers do this kind of thing for the love of it and provide no explicit support for their roms. Any and all risk is taken upon yourself but in most cases caveats will have been picked up by someone before hand.
Sorry if I've mentioned some things you already knew but I thought to add some info applicable to other newcomers.
Enjoy hacking!!
Thanks both.
I guess I'll have to use a non-Hero ROM then. As for the BT file transfer, I've seen at least one Cupcake ROM with it enabled and available as an option in the BT menu. I don't know what ROM it was though, I think I saw it in a Youtube video.
P.S.: I noticed that this thread was moved to "Sapphire general", sorry for put it in "development", I did it for it was related to Hero ROM's. Thanks mods for move it.
A2DP works for my Sony Ericsson HBH-DS205 - music streams flawlessly.
However, the call feature does not work - is this another common bluetooth problem with the HEROs?
So, I have searched all over these forums, and cannot find a difinitive answer or solution. I have problems with A2DP when connecting w/ the BT in my car, since installing a 2.1 ROM (currently DC 2.09.01). When connected, the music plays about twice as fast as it should, then slows down, then speeds up again. Conversley, Android 1.5 worked fine. There has been a lot of talk of BT issues, but it doesn't appear there are any solutions. Am I correct, or has someone found a solution? THanks.
ZenEXP works if you dont mind switching.
I have had those problems occasionally with all 2.1 ROMs I have tried. Usually, if I pause and then unpause it solves the problem. Sometimes I have to do it more than once.
I'm currently running ZenEXP and I've had the problem a few times, but it has been significantly less than with other ROMs. However, AVRCP hasn't been working with ZenEXP, whereas it has worked on other 2.1 ROMs, such as DC.
So, with the unrooted stock Sprint 2.1 software, A2DP works?
The Darchdroid ROM actually fixes this problem! I had the exact same problem as you with playing audio in my 2010 Mazda 3 and Darchstar's ROM fixed it for me, it's the only ROM I have found so far that fixes the bluetooth
I have a problem with my bluetooth headset when I'm playing music, the music stutters alot, I almost have to hold my phone a certain way with very little movement in order for it to play decently. Any solutions on that problem?

Turn off/disconnect headset while playing music fixes studdering for me in settings under bluetooth for the connected device. Disconnect the ' phone' while playing. Haven't really tested this on anything but my kenwood head unit.

here's a reply I received from HTC support:
Hello, I understand that you have had issues with your bluetooth since the update for your Hero. With the update, the entire bluetooth stack was updated, and thus some bluetooth devices that previously worked are unfortunately no longer compatible. While we have not heard any information about nor made announcements about any upcoming patches to address this, it is not at all out of the realm of possibility. Otherwise, you may want to try a different bluetooth headset. I do apologize for any inconvenience you may have experienced. If you have any other questions, feel free to contact us again. You can find additional support at support forums at community.htc.com. There is also a customer satisfaction survey for you to take if you are interested.

Bluetooth Stack?
So is it possible for one of the developers on this site to rewrite the bluetooth stack or copy the old one from 1.5 that worked?
I have a Panasonic TH12 bluetooth home phone that worked fine before 2.1. I recently bought an AT&T bluetooth phone and it does the same thing. Will pair but not connect.

I have to call BS on this. (Not on the post, on the reply)
Why would any company not support legacy hardware as simple as Bluetooth. Especially since most devices aren't even Bluetooth v3/v4 standard yet. And Bluetooth 2.1 is 1. Not very old and 2. What 90% of Bluetooth device still manufactured are! and its been around since 2006!
I honestly can't believe a company is going to just say "Oh its to old" instead of fixing their crap. as far as I know v3/v4 is fully backwards compatible to 2.1 because they include "Classic Bluetooth" protocols!
Not to mention I doubt the hardware in our phone is even capable of v4 stuff. I'll have to do some more research on what BT chip is in the phone. Utter BS.
Either Phillip or HTC is a moron.
CDMA Hero Specs for BT:
Supported Profiles: HSP 1.1, HFP 1.5, A2DP, AVRC, (OPP, PBA)
version 2.0+EDR / possibly upgradeable to 2.1+EDR, plus OPP and PBA profiles
2.1 FULLY backwards compatible to v1. Meaning HTC built the crappiest BT Stack allowable by law to say it includes it. May as well have not bothered.
Someone could probably redo things with AOSP and a newer bluez stack.

Yeah, I just bought a BT USB adapter so I could exchange files and synch and stuff. I got it to work ONE time and all it did was pass 200 of my contacts to my phone from my PC. Like it was just waiting to upchuck on me. After that, nothing.
There's three hours of my life and $8.99 I'll never get back.
Bluetooth is pretty much the #1 complaint that users have been posting on the Sprint Community Forums (here's the HTC Hero section). Nearly all of those complaints say that Bluetooth now doesn't work at all or just plain sucks on the stock 2.1 Sprint/HTC release. Which probably also means that any ROM here based on 2.1 stock will also suck it up bad with Bluetooth compatibility. Known problem, no one has done anything about it yet. It sounds like AOSP ROMs don't have this issue, so at least that's good.
All,
Does anybody have any fixes regarding the sound quality when using Bluetooth A2DP protocol? I use my Evo to mate with a Bluetooth receiver so I can listen to Rhapsody over my home stereo. The sound quality is flat. The high frequencies are not present. It sounds like a bad quality MP3. I know that its the A2DP causing the quality issue as directly connection (through 3.5 jack) is awsome.
The Apple 3GS A2DP sound quality was awsome. I am not sure why the Evo is not sounding good. Any help would be most appreciated.
Thanks,
Lance
use the cyanogen rom--this uses a bitpool of 53 giving you the best bluetooth quality possible. the stock/sprint/htc bluetooth drivers are set for a bitpool of 32
Is there any other ROM that has the bit pool set to 53?
Lance
Nope all Sense roms use HTC's ****ty low bitpool setting. This is why I'm running CM as well it's the only rom I can A2DP to my Sony Head unit and get good audio. I attempted to contact HTC about this issue here's the juicy details
Here's my initial question
I have terrible static when streaming music over A2DP on my HTC EVO to my sony mex-bt2800 car radio. If I use CyanogenMod 6.0 which uses a open source bluetooth stack my A2DP is crystal clear to my radio. I have used logcat to look at whats going on I dont know if its a bitrate problem or a bitpool problem or if my radio isn't in your acoustic database.

Here's the response I received
Although the android software has been updated to be more compatible with Bluetooth headsets and car kits. Most of the time a Bluetooth manufacturer will have a list on there website stating devices they have found compatible, but this is not always the case. From the information on your issue it seems that your device is simply not fully compatible. The only thing we would be able to recommend would be to try another headset.
Then my response back
I would like an Engineer to read my question if possible since I don't think you fully grasp what I'm saying here. First My EVO's Bluetooth A2DP WORKS 100% clearly when using a Open Source ROM which implements Bluez Bluetooth stack http://www.bluez.org/
When I run your Sense UI ROM the Stock ROM you release which uses your own proprietary Bluetooth Stack I get static in the background so you cant really say its my phone now can you? Its your implementation that's not working properly. I'm not about to try every car stereo till I find one that works with the EVO when I know my stereo can work perfectly with my phone when using a properly coded open source Bluetooth stack.
Here is some extra info from a logcat that shows how your Bluetooth makes a connection through A2DP and what I believe is too low of a bitrate or bitpool setting
http://forum.xda-developers.com/showthread.php?t=708265&highlight=bluetooth+bitrate
PLEASE DON'T GIVE ME A ANSWER THAT YOU JUST READ FROM A SCRIPT. I would like a true response from someone who understands and can grasp my question fully like an engineer or a developer, when you give me a generic response of oh your Bluetooth headset isn't compatible keep buying new ones till you find one that works, that really makes me upset since you didn't even read my question it's a car stereo and there not cheap.
I await your educated answer.
And there final bull**** reply
We apologies for any inconvenience you may be experiencing. We will document your concern for review in development of our upcoming devices and future software updates. The situation is still an incompatibility with our device and your car kit weather on software or a hardware level. Unfortunately at this we have no further information beyond what has already been provided.

Well I commend you for trying. This is something that makes me want to tear my hair out so I would love to see this resolved as well.
good on ya mate.
anyone know how to get another bluetooth stack on stock rooted 2.2?
I asked Flipz a while ago but I don't think he's looking into it. I also asked Netarchy he said he would look into it sometime but that i shouldn't hold my breath since he hadn't even looked at the code yet. HTC has released the source for their Bluez implementation so all we need is a dev willing to look into adjusting the bitpool setting.
This is a HUGE problem. I am flashing CM6 right now. HTC I am very disappointed with you..
The cyanogen rom also has great dsp equalizer
CyanogenMod will also make you a tropical island than transform your EVO into a jet plane and take you there ;-)
But in all seriousness, yeah, CM6 has BT fixed. One of my friends nagged Cyanogen about it last month, and he patched it right away.
I wish somebody could help us by increasing the bitpool on the Bluetooth driver. The Evo would be so much more enjoyable (for me at least) if the sound quality was better thru A2DP.

It would be nice if there can be a patch of some sort...
Just an update today I got a call from HTC customer service since i gave a poor review of my experience on a survey they sent me. Talked in great detail about our problem with the Bluetooth stack told him about the bitpool setting how its 53 on CM and 35 on there roms. So hopefully on the next update well get a fix for the Stock Sense UI rom.
^^LMAO!!! dont blv the hype
I read that the CM6 ROM has this issue fixed. I have also read reports that the ROM email client doesn't support word wrapping (which I really do need). Can anybody confirm this?
Also,
Can anybody in ROM land please create a patch or an update to their ROM which increases the Bitpool to 53? I understand that the Bluetooth driver code has been released.
Thanks

That was a streaming issue, not a bitpool issue.
The BT audio was a lot better on my TP2 when I updated the registry bitpool to 48 from 32.
I wish they would fix it.
