Question about MHL on Nexus 7 (again) - Nexus 7 Q&A, Help & Troubleshooting

Ok, I have read the articles in regards to MHL not being supported on the Nexus 7. My question is if this is due to the hardware not supporting it or is it because the OS itself for the Nexus 7 does not include the modules needed to support MHL on the Nexus 7. Anyone have any idea?

Hardware issue I think. You can't have read well!

Well, its not that I didn't read well, but most articles just say it does not support MHL. There is no clear answer in what I have read that clearly states whether it is due to hardware or software. They say OTG is not supported, but installing stick mount on a rooted nexus 7 gets around that. What about MHL? Is it because a chip is missing from the Nexus 7 so that's why it is not supported? If so, would it be possible to create a module that connects to the mini-usb or the 4 pogo plugs to add this functionality? If not, could there be driver like stick mount that enables this functionality?
It's a great device, but it would be nice if it did support MHL somehow.

From what I understand anything that can be done in hardware can be done in software

From what I understand anything that can be done in hardware can be done in software but slower, however maybe the signal that needs to be sent from the micro usb is not present currently, so if someone who knows about the internals were to write something it should be possible, I think if you can emulate a whole pc why not a mhl signal?

USB Host

First at all thanx on all great things maded here. Hers is my first post on XDA I hope so that I am not going to miss subject or ask question allredy asked or be miss understud by my bad English.
Here is question
Is there a chance to my galaxy tab be usb host for usb keys and memory sticks.
So i can connet usb and use and copy files form there.
Something like it can Nokia N8 or other tablet devices from far east with android os.
Thanx in advanced
Sent from my GT-P1000 using XDA App
I seriously doubt it, mainly cause of my limited knowledge on hardware support in the android kernel I can't give a definite answer, but on the assumptions that usb host is a complete driver and maybe even hardware dependent (which I assume would be missing on the tab cause if not it would be a sales point and available already). So my view, 95% sure that it's 100% not even 30% likely that it's probable(ish)

All stats are flawed ! gingerbread supports near field comms, dont make a difference if you aint got the hardware
So i still think usb host protocol missing from usb controller on tab
So true. Maybe that is what that little USB connection kit accessory was for?

Doubt it, its just a convertor, to add usb host through the tab socket, it would kinda need host already samsung may add it in other versions of the 7 though. Not my p1000 me thinks

HDMI out and OTG support?

So, I know it just came out today, but damn this device sounds amazingly superior.
So does anyone know if it has HDMI out or Micro-USB to HDMI out? Anything about OTG so we can use usb keyboards, mice, flash drives, etc?
I am seriously considering selling my iPods for this thing. I already have a Kindle Fire, but I might sell that too for this thing...

HDMI out through MHL otg suppport is unknown but considering its a nexus it will be easy to add so consider it supported

That is what i am thinking, since it is a nexus product the developers should be able to rape the nexus7 with alot of goodies.
If it does not have the innards to support it, MHL support might not be so easy to add in. I'm just hoping they're not holding back for the sake of Nexus Q sales. But I suspect, that may be exactly what is happening.
We'll see, I hope it has the support built right in.
USB keyboards, mice and "other devices" are supported.

Other things may be supported, however, Engadget has confirmed the Nexus 7 does not support MHL. It has no way to connect an HDMI cable and get video output to a TV/monitor. Ah yes, it appears they are holding back for sales of that Nexus Q...

Where in that article does it confirm no MHL support? They even suggest using an MHL adapter if you want HDMI out...

Miracast on the Nexus 7?

In articles released today, Nvidia said the Tegra 3 chipset will support miracast (an open streaming tech similar to DLNA) for mirroing/streaming to other devices/ monitors. Will the Nexus support this and would this be their workaround for forgoing the MHL/HDMI? Or would it only be on future models? -Ara

I'm very curious about this too.
I've looked into this briefly and from what I gather, any device that supports WIFI direct should be able to do this. I think I read somewhere that the N7 has wifi direct. Miracast is only a standard. There are other non-standard devices out there that can also do the same thing, but requires changes to the core android files.
Search for xbounds on youtube and the internet. You will see some demos of it. it requires an hdmi dongle that has wifi on it that communicates with your device.
In any event, if the N7 doesn't support miracast, it will support xbounds via a custom ROM (if and when somebody decides to build a custom ROM with xbounds integrated). Then all that is required is the xbounds dongle. Unfortunately, there is not much information on xbounds and when it will be released.
What would I need to purchase to get this working?
Hopefully, we don't need to buy stuff, we just need to update our devices when miracast comes down. There's a list of compatible devices on the Wi-Fi Alliance website. -Ara
EDIT: here's a link to the tegra explanation of miracast, taken from an article on the issue. Yeah, a dangle may be involved depending on the setup. http://www.nvidia.com/content/PDF/tegra_white_papers/tegra-miracast-whitepaper-final.pdf

I've not found any hardware that you could plug into say an HTML Monitor that will work with this yet. I do think it will be coming available soon though.
hope so
I reckon it will work with a Nexus 7. Hopefully the dongle isn't too expensive and my Nexus 7 will be my new PSone.
Shouldn't need a dongle. Maybe a Raspberry Pi but everyone should have one of those anyway Search "Android Transporter" for more info.

Nexus Q might get Miracast support
Nexus 7 and most Tegra 3 (also Galaxy S3) phones/tablets can get a fw upgrade to enable miracast (most that support WIFI Direct probably can have Miracast enabled).
Now that google is having another round of tinkering on the Nexus Q before release we might end up with Miracast support in it as well.
Personaly I think Miracast will be added out of the box and maybee even Google TV.
I only hope that it won't be possible to disable mirroring from inside an app using the API, if so I'm sure some streaming services will disable mirroring of the screen while using there apps lika HBO Go have done to Airplay

Using a Raspberry Pi would be like a dongle... I'd like to get my hands on one to play, currently, there is a 12 week delivery time on those as well and you most likely would want it in some sort of case for it as well.
While most likely a solution, not a real clean one for mass marketing. That will come though.

Hopefully it does include support, but that is still a bit pricey and also not very portable.
Think of something you put in your briefcase, take out for a meeting, plug into the HDMI port of whatever display is in the room and play. So it needs to be portable, reasonably priced and easy to use out of the box without a lot of fiddling with it.
widi and Miracast adapters
I am thinking that these will do what we need on the display side. Now to enable it on the Nexus 7.

Otg support

Does Galaxy tab 4 t231 have USB otg support? If not, can it be enabled by any method? Planning to buy this tablet. Please answer.. Thank you for your time
Sent from my Nexus 4 using XDA Premium 4 mobile app
Would really love to know this too. It's my understanding previous versions of the Galaxy Tab support USB OTG, and would love to enable it on the Tab 4.
On my smartphone I have an option in settings to turn OTG on and off, unfortunately no option seems to exist on my Tab4. Assuming the Tab 4 has hardware support for it, how would I go about enabling OTG?
Bump...
Would LOVE a solution as well~!:good:
Ran USB Diagnostics. As of now there is no support whatsoever but a custom ROM or Kernel may be able to enable it. I suppose there is a slight chance since the larger variants have OTG support and the hardware is similar.
Edit: Playing around with some OTG apps, it appears that we do not have hardware support so there's about 70-90% chance the tablet will purely not support it and trying to do so would be impossible.

I ran that same app on my Tab4 as well, unfortunately I wasn't able to understand everything the app told me so I concluded OTG support on the Tab4 was inconclusive =P
Considering OTG is supported on the other Galaxy Tab devices, what reasoning would Samsung have to not enable this feature on the Tab4 7.0? Especially if the hardware is the same (or very similar) it just doesn't make any sense to me why they wouldn't give the Tab4 7.0 OTG support as well. It's actually very frustrating in 2014 that this Tab doesn't support OTG. I am almost considering returning it solely for this reason (I haven't yet, because I'm very pleased with everything else the Tab4 has to offer).
My cheap, Chinese sub $100 android ICS tablet I bought last year had OTG support! What gives Samsung? I sort of expect more from a major brand like Samsung.

So, I may be wrong but I believe the problem may be in chip set itself, since its Marvell CPU (I never heard of this company). However, the Tab 3 also carried an older Marvell CPU, which they were able to overcome this problem with a custom Kernel. So, may be this tablet has slight chance of having OTG support but Scumbag Samsung decided that they don't the cheaper tablet to sell.

Well I'll certainly be holding out on that slight chance for OTG support lol. I was really looking forward to using my tab 4 as a second display with DSLR Controller, so you can imagine my disappointment when it didn't work =/
Either way, if a dev ends up seeing this and wants to implement this feature, let me know if I can do anything help (beta testing custom kernels) or whatever, just let me know. I'm more than willing to help move this forward, even if it ends up not working.
Hi, on my t235 otg works. For now i've tested it inly with usb storage sticks (8gb tdk, 8gb toshiba and 16gb verbatim) - stock file manager and total commander fully works with it. I dont have any mouse or keyboard to check that it works on otg.

HI Osiris, do you got OTG work with Tab4? i'm in a similar situation with a Canon 70D & DSLR Controller...
In the page of DSLRController is a list to compatibility & models
best regards
i am willing to test the otg kernel i have a cable and a few different usb devices i would like to use with my wifi only
unit
I was curious if my Tab 4 has usb otg support. Turns out it did, even tho those usb otg checker apps said it didn't. I was able to open up the stuf on my usb stick. My model is SM-T330NU and i'm on 4.4.2
Also, it also supports external dac (Tested with Fiio E17) and it works with spotfiy. I'm starting to like this tablet even more .
I would like to buy this cable in order to use my Tab 4 to charge my Nexus 4. (Only need this on the road charging done when I'm on vacation, which is every 2-3 years, making buying a battery bank not worth it)
Would this cable work fine?

Please note my main objective is not accessing USB keys or HDD's, but purely use the cable to charge my phone. Accessing a USB media storage would be a bonus.

Hi is that a 7" or an 8"? The 8 has otg but my 7 doesn't as standard. If it's a 7" how did you get it to work? Would LOVE to get OTG working on my tab4 7" as it's literally the only reason I bought it and didn't realise and (wrongly) assumed) it would have it.

[Q] what modes support wired internet out of the box?

I was thinking about getting my father a Nexus 7 tablet,
and for reasons I'd rather not go into. I'd need a model that would support using a usb Ethernet adapter,
I've heard that some models, support that and some do not.
How do I know what model to order?
And where can I get one that would support that?
It depends on the chipset used in the USB Ethernet adaptorand whether the driver for it is in the kernel you're using. A complicating factor is that manufacturers sometimes change the chipset whilst keeping model/case styles the same. Google "nexus 7 otg Ethernet" and read.
