[Q] Bluetooth Pairing Issue - Nexus 7 Q&A, Help & Troubleshooting

So I have searched the ROM threads and this thread and haven't found answer to my question so I am hoping someone here can assist me.
After installing CM10.1 latest, AOKP latest, and the latest Paranoid ROMs onto my N7 3G I am having a weird bluetooth issue. When I try to connect it to my car (2011 Ford Edge with Sync My Ford Touch system) the N7 will not let me enter the pairing code my car presents. Instead it presents its own pairing code which my car recognizes the first time and lets it connect. Then whenever I disconnect bluetooth (either by turning off the car, or Bluetooth on the N7), the car will not connect because the tablet says the pairing request failed because of code mismatch. It never did this prior to the latest versions of the above ROMs, and I haven't tried a pure stock ROM (oh, tried Timur's ROM too, but that is CM10.1 based anyway), so I am not sure if this is just the way the latest code base works or not.
Please help!

CM --> MIUI --> CM Bluetooth Dies!

Hi folks,
I tried out the MIUI ROM and liked it, but for various reasons, I wanted to go back to CMod again. So, I restored my NAND backup of my CM6 install. When I did this, I noticed that Bluetooth was no longer working correctly, i.e. it would pair successfully with my radio, but it failed to connect to it.
When I restored my MIUI backup, bluetooth worked again.
I cleared every cache known to man and once more returned to my CM backup, but once again my Bluetooth failed to work.
In the end, the only thing that seemed to fix the problem was wipe all the settings (again) and flash the latest CM nightlies (very nice btw!). After this, all was well.
I am attaching a logcat file if anybody is interested in the Bluetooth output. My totally uniformed suspicion is that it had something to do with the way MIUI uses the Bluetooth stack to get the radio working, but I'm sure somebody out there knows better than I do.

Problem with Bluetooth paring on CM6 and CM7

Hi,
I've been trying to use CM6 and CM7 but with both versions I run into Bluetooth pairing issues. The main problem is seen when trying to pair from my phone to my car. I get asked to enter a pin (that has been displayed by the car), but only get a few seconds to do so before I get an error message displayed. I've tried various kernels (same problem), and I'm using the latest radio rom. Things seem to be fine with stock 2.1 and with wildpuzzle. When flashing the roms I'be made sure I clear the cache, the dalvik cache and reset to default. Is there anything else I can try?
Thanks
Andy
Hi Andy,
Did you ever get a fix for this? I am having a similar issue, however my device does not give me a prompt at all for the bluetooth passkey.
Thanks,
Jessica
Use bluetooth file transfer from market. It works
Didn't work for me, still looking for a way round this.

Bluetooth Auto Connect Problem

I need to re-pair my plantronics bluetooth headset every time i want to connect to my phone. it doesnt auto connect furthermore it doesnt connect when i tap on its name in bluetooth settings. i need to pair it each time i want to use it. It was normal 2 days ago. And the headset works normal i tried with other phones. I formatted persist and firmware with new clockwork mod recovery i wonder if it is because of that. I tried several roms including the flashing stock 4.3 JWR image from googles site with flashboot. but the problem persists no matter what i do. Please help me it is driving me crazy.
Nevermind I solved the problem by doing the things in this post

It seems that the problem started because i have formatted the persist folder.

Powerdown Video
Hey there,
I was finally able to install this rom after a long Sunday of learning and failing and finally succeeding late last night. My question is in regards to the powerdown video that is supposed to play in the case of power loss. Is it supposed to play every time disconnect my nexus 7 from power? I haven't installed it in my car yet but I've been playing with it and it doesn't do anything when I disconnect it from the power source. Anything I might be missing? I have the following options turned on: Fixed install mode, fast charge in host mode, and firm sleep. Any help is greatly appreciated!
Need some help
Running Autodroid 1.2
Issue #1 Everything seemed to be running great rebooted on Sunday and now it no longer recognizes my usb charging cable or Otg cable. So power down can not take place as well as charging . What do you recommend? Should I re-flash the kangaroo kernel that is on the 1st page?
Issue # 2 I am using a usb hub with a charging port for my setup. I want to use a behringer UCA 202 dac . How should I set this up?
Any help on either would be great.
Newbie Autodroid summary and Nexus 7 car solutions in general
I apologize if this is the wrong place to post, but I'm trying to do a Nexus 7 in dash head unit replacement and I have some questions.
First, a little about myself. I'm an Android (and XDA) newbie, first post, but I have some programming experience (C and some assembly). I am rapidly learning about Kernels, ROMs, etc. I try to learn as much on my own as I can so I won't be a pain here. I know wiring, and am an electrical engineer.
My problem is this; I need a solution to allow the Nexus 7 to OTG charge, or maybe it's possible to use the side dock connector for charging? If I OTG charge, I read that Autodroid may not support that, but Oxydo does? I could really use a source of information (youtube video etc.) so I could learn how to make this work.
And, for that matter, how to program my Nexus. I've seen how to root it, and I think I can do that, but then should I flash it with Oxydo kernel and then Autodroid ROM?
Any help would be greatly appreciate. I'm trying to get this up for myself and for my 17 year old son's truck. Also, thanks for all your sharing of code and help!
Autodroid supports Otg charging as is.
What I would do is go to the play store and download MuliRom manager.
This will make it easy to set up MultiRom.
Multirom lets you install and uninstall multiple roms without messing with your stock rom.
Hope this helps
USB issues
Ok I have been running autodroid for a few weeks. So far it is good. I am having a few issues though with it.
Has anyone been having issues with charging since adding this ROM. Although it is charging it doesn't indicate that, so otg doesn't work. It can't see any usb attached items and such.
My setup includes a Behringer usb dac uca202. Although I plug the dac in the hub (sometimes without the hub) and reboot the devices from off I still get not response; the dac light does not light up, sound still comes out of the tablet speakers. Can Anyone using this setup help me figure this out or at least put me on the correct path
I want to add a backup cam to my system, but there appears to some real issues with this setup. Any help or advise would be great. I want to be able to have it come on as soon as i put the car into reverse

Thanks! That's an interesting idea. I may try that. Are there any disadvantages to this approach besides the extra storage space (which seems like it wouldn't be that big of a deal?)
I just rooted the device, so it's fresh and ready.
On the other hand, I found someone with Timur's ROM, so I have two options now. Autodroid seems a little more up to date, but I'm not sure. Maybe it's just a preference?
Thanks for your help. I know a lot about a lot of things, but in this area, I feel a little like I"m walking around blind! I'm just trying to learn as much as I can.
I don't see any disadvantages and the storage space is minimal.
With MultiRom manager you can also remove the rom as easily as you installed it.
It has a multi boot feature on startup so you can run your stock rom or any other roms that you have installed.
Autodroid is a rom and and Timurs is a kernel. With the Autodroid rom you will have a lot of features which are geared toward an in car installation.
If you decide to use Autodroid don't install it like they show in the op.
There is an easier way to do it using MultiRom.
Advice please
Can I plug in a FIIO D3 into a powered Anker USB hub. I have tried 2 behringer UCA 202 and both connect but no sound from either. I have read the USB ROM tutorial and I know that I must turn the devices off them mount the dac and turn the device back on, but still I get no sound. Help me

That sounds really cool.
I know Autodroid is a rom, but I thought Timurs is a kernel and a rom?
Autodroid can be had at the play store if you sign up to be a tester. I wonder if this is a different version, or I guess somehow it's changed into an app?
If I use multirom, how should I install autodroid?
Thanks so much for your help!

The first thing is to get MultiRom Manager installed and working and then we will go from there.
When you have installed the app and opened it you will see a box that says install/update.
If the first two boxes match what is in the status box above this you are ok, if not check these boxes.
If you see a warning in the status box about the kexex hardboot patch, check the third box and in the drop down menu pick which version of Android you have,
If you aren't sure of which version you have, on your tablet go to setting about tablet and it will show the version.
Tap install and follow the directions.
When this is susessful we will go to the next step
Is there any way to make navigation bar bigger ? I need it to be two times bigger.
What should the ROM look like when installed correctly? This is my first time doing a custom ROM and it appears to be installing correctly but the OS is not any different it seems. It just has Apollo and SuperSu. No additional features anywhere it seems. (Nexus 7 2012 Wifi)
It says....
Kernel Version

I rooted and installed CWM. Downloaded the ROM for the first post, wiped dalvik, wiped cache, cleared everything, and then installed the ROM from zip. It doesn't appear to be working unless I am just missing a step. I tried using my new Behringer UCA222 with my OTG Y cable. UCA222 has power, tablet charges, sound plays from tablet speakers....
Any help to get this working out be nice. I don't know what I am doing wrong.
I have noticed a problem with power event manager!
I have disabled waking the screen on power because i can wake it up anytime using my remote control.
The problem is that if my screen is off and there is a power loss then power event manager sets airplane mode but the screen is switched on and stays on.
Anyone elese is having the same problem?
FI Problem
Hello,
i have a Strange Problem with my autodroid System.
In the Power Settings, it is not possible to set up the FI Option.
Everytime i change these setting, it goes back to off.
Because of this Problem, i checked the Autodroid installation an did a new, fresh install.
Changed the OTG Cable and the Power Adapter.
Nothing changed this
I tried again an older 4.2.2 Rom, here workes everithing perfecly with the same OTG and Power Adapter.
Because of the 4.4 Android, i would most likly use Autodroid.
But without a solution for this Problem, i could not use it in my Car.
And i read here, that other Users didnt have the Same Problem.
What did i do Wrong here?
Best Regards
X2 on a bigger navigation panel¡
I am having a problem with everything on the usb hub being restarted everytime I turn off and turn back on. So it has to rescan media, and i have to accept dialogs to use the FM tuner because it doesent remember it used to be there. Is it because i am using stickmount? I have it in locked mode, and I thought thats what it was there for...?
Edit: fixed the issue, I didn't realize the Rom had built in functions for mounting the external drives.
Rear View Cam
Hi,
I posted this in the ROM-thread before, but got informed to post it here in the Q&A thread instead, so it's kind of a double post.
Tried to search the thread but didn't really find the answer, but does this ROM still rely on Carcam as the app to show the video feed from the Easycap, or did someone actually write a new app?
Love the work on this ROM, as I loved the Kangarom before it. This is going in the car, if I can just get the shaky Carcam to actually work after a deep sleep as well...

I have done a lot of research. Maybe i missed something. thanks in advance.
Trouble Installing Autodroid 1.2 on Nexus 7
So I've been attempting to install Autodroid 1.2 on my Nexus 7 Grouper, but I can't seem to get the bugger going. The tablet originally had Lollipop (5.0) installed.
So here is what I did:
1) Installed the stock 4.4.4 ROM (Build Number KTU84P)
2) Installed Bootloader 4.23
3) Installed TWRP 2.7.1.1
4) Installed SuperSU (rooted the tablet).
5) Performed a normal wipe.
6) Installed Autdroid 1.2 for Grouper
After doing the above, and going to the "about tablet" setting, it displays the following:
Kernel version: 3.1.10-kangaroo
Build Number: KTU84P
So it looks as though the kernel installed fine, but the ROM itself doesn't look the part.
A few more things to note, OTG seems to be kind of funky. I can insert a USB drive and mount it using Stickmount, but the drive doesn't show up under Settings->Storage.
Oddly enough, charging with OTG works.
Any help would be very much appreciated.

Bluetooth issues

Hi guys, i've some problems with my Bluetooth.
Yesterday i've tried to connect to a bluetooth speaker but my device seems to not find it. The speaker is working with the devices of my friends.
Tomorrow i was trying to connect my p8lite to the bluetooth radio of my car. My brother has a p8lite rooted and we have the same version(b574), he's finding the radio's bluetooth, but i'm not finding it. So my question is: is this an internal problem or a software side issue?
I've tried to reinstall the complete OS, wiped all partitions, mounted and searched on the internet but i didn't find nothing that can help me.
Is anyone else having this problem too? How can i solve this problem?
Thanks
