Android 2.2 (Froyo) and Pairing with Car-Kit/rSAP/HFP

Hello everyone,
I would like to share my experience in pairing my Galaxy 3 with the Car-Kit. The configuration is as follows:
Phone: Samsung Galaxy 3 GT-i5800 with Android 2.2 Froyo (not official)
Car-Kit: Bluetooth Touch-Adapter, No: 3C0051435TA
Auto: VW-Passat, Year 2007
In the VW-Specification this phone is not at all supported, and was not possible to pairing with the Touch-Adapter.
Than, I looked into the bluetooth configuration and made some small changes (my phone is rooted) to activate Hands Free Profile.
And it works!!! now I can pairing my phone and get the contacts form SIM into the adapter.
If you're interested I can provide the modified config files and for the users with no rooted phones an update.zip (I must try first).

Yes, please do ))
I've been having the same problem.

Ok. I'll try this weekend to post something.

Bluetooth configuration
Hello,
As I promised, the user with ROOTED phone must unzip and overwrite the attached config audio.conf file in the folder
/system/etc/bluetooth/audio.conf
The config file is from Android 2.2 (Froyo) but you can look to the similar settings for other versions of android.
If it works PLEASE give me a feedback with the following infos (useful for other users too):
Phone: - brand, model, android version
Car-Kit: - brand, model, etc.
Auto: - brand, model, year

Will do, thanks a lot.

It doesn't work, keep getting "incompatível phone" error.
Tried swapping the audio config file with yours, deleting autopair and blacklist files, restoring the old audio config without restoring autopair and blacklist...
No results.
My phone is an HTC Desire with unofficial froyo.
The car is a VW golf from 2010, equipped with a premium rcd 510 radio.
Thanks and have a nice weekend.

I'm really sorry. I flashed my phone with a new version, rechanged the audio.conf and still works. But for HTC there are mod roms? Aren't they? These mods are supposed to be better than the stock ones!?

I'm using the latest MCR Rom witch is quite good,i think the problem is brand related.
This Android - RSap incompatibility is well documented, its open issue #4402 .
I read somewhere Samsung had implemented RSAP in their software, so maybe it's brand specific and only Samsung Android Phones will work with RSAP.
Thanks for your kindness.

[Q] Bluetooth Smart in Xperia L?

Hello,
First of all I want to thank you your work.
I have a questions I don't manage to answer reading forums.
Xperia L supports Bluetooth Smart 4.0. Well, after installing custom rom CM12, 12.1, Resurrection, the phone doesn't detects my Smart Bluetooth devices (Heart Rate Polar H7). Sometimes they are detected after restart, but the most of the time they are not detected. Bluetooth classic devices no problem.
I have made a clean installation of this roms.
I don't know if someone have some idea to change the bluetooth drivers of the phone and make the Blue 4.0 start. If you can help me.... With BLE Checker the result is ok. But then, it doesn't work.
Thank you in advance.
Device: c2105
ROM name: CM 12 dated 23th May
Build number: CM_taoshan-userdebug 5.0.2 LRX22G
kernel version and its settings: [email protected]#
I flashed CM over 1.5.3A.1.17 Stock

Hello! may you need some extra apps....for my smartband with BT4.0 i needed the app "smart connect" from sony.... may try it....its for free

Sorry, it doen't work with this. I think it could be related with the bluetooth manager of the mobile.
Any more idea?? Thanks!!

Anybody operating with Heart Rate monitor on the Xperia??

Greetings and welcome to assist, as miui was never originally made for your device like all custom roms there will be bugs. You are probably best asking in the thread you linked to see if anyone else had the same issue

I'm using the SM-N986B/D variant and had my android auto connect to my car unit (Pioneer AVH - Z5090BT) and ever since got the update to A11, it has stopped connecting. I tried changing cables to connect to know if there was an issue with the cable I was using. Anyone has any solution to this?

This is a known Issue on some devices and some cars.
Follow this thread for details.
