Android Bluetooth Profiles not enabled in GUI - Android Q&A, Help & Troubleshooting

Hi All,
I am new to bluetooth module in Android.
I am working in Android Lollipop (5.1.1) customization. I am able to integrate the BlueZ stack (5.43) into Android 5.1.1. Since we disable default blueroid stack. I am able to TURN ON/OFF the bluetooth, pairing, sending some files/pics/data happening successfully (we are using default bluetooth app which is provided in Android 5.1.1).
Now I am working with A2DP and AVRCP profiles. I enabled these two profiles in bluez stack (5.43). i.e configure.ac., but I am not able to see enabled profiles or any other default Android profiles in GUI (settings/Bluetooth).
Questions:
We should do any modifications in the Android framework level to enable the profiles, if so, please send the required changes to be done.
Any other changes required to enable the Bluetooth profiles in Android 5.1.1.
As per my understanding, when pairing happens successfully with other devices, we are not able to pair the profiles (a2dp and avrcp).
What are the issues to cause the problem in Android Lollipop regarding the bluetooth profiles? I tried to search in many websites and Google but I did not succeed.

Bluetooth Features Confirmed after Android 2.1 Update

I can confirm that Bluetooth Dial-Up Networking (DUN) works after the 2.1 update using PDANet through my Sony VAIO on the Rogers Network.. yes! now I can fully take advantage of my 6GB data plan without wires!
Also, the PhoneBook Access Profile (PBAP) as well as pulling your recent calls list (not sure what profile that uses) works fine with Android 2.1 using my SE HBH-DS980 headset.
However, on an incoming call, the phone doesn't push the CallerID tag to the bluetooth device. The same goes for the MusicID tag when playing music. From my intuition, I don't think these 2 features require a specific bluetooth profile but will rather need to be implemented in the music or dialer applications to function. I'm not sure why SE is leaving this out on the 2.1 update as it is a huge selling feature for their MW600 headset. All SE phones powered by Symbian or part of the Walkman branding all had these features right out of the box, and the X1 running Windows Mobile had it as a 3rd party support (ie. smartwatchm). It would be nice if a developer can add these features for Android since SE won't.
It also doesn't have the Service Discovery Application Profile (SDAP) to be able to provide the list of available bluetooth services to the master device. This was tested using my SE X1a. So to actually find out what services are supported, you'll have to find out the hard way.
Can anyone tell me what other bluetooth profiles are available now?
Summary:
Confirmed Supported Bluetooth Profiles in 2.1 Update:
-Hands-free Profile (HFP)
-Headset Profile (HSP)
-Object Push Profile (OPP)
-Audio Video Remote Control Profile (AVCRP)
-Advanced Audio Distribution Profile (A2DP)
-PhoneBook Access Profile (PBAP)

Ringtone over bluetooth
Hi there. i think this is a problem shared by many users:
i habe a Bluetooth Handfree, in this case, FIAT Blue&ME. When i connect for example a Nokia phone and the phone rings, the ring is transfered to the audio systems of the hands free. With my X10mini i hear only the default RING RING from the hands free :-(
Is there anyway to enable handfree transfer of the ringtone in Adroid?
there are persons that describe the same problem but not for android: for example at http://forum.xda-developers.com/showthread.php?t=634494
By the way also SMS messages cannot be transfered to my Hands free Blue&Me. Anyone have idea how to fix this?
I think a new application to solve ringtone transfer to handsfree would help ALOT of users.
Regards and thanks..
OpenWatch is an app that is downloadable from the Market that allows bluetooth devices (like SE MBW-200 Bluetooth watch with lcd screen) to receive call/SMS/alerts/music player controls/etc. It supports a couple of other devices as well.

The "Audio Video Remote Control Profile (AVCRP)" is still at v1.0. We need a minimum of v1.3 to display track information on MW600.. :-(

Bluetooth 4.0 switch

Hi,
this might be a silly question but is there a way to activate bluetooth 4.0 in Android 4.3 and leave "classic" bluetooth switched off? The reason I'm asking is that I'd like to use power-saving BT4.0 to detect Texas Instruments SensorTags within reach and perform several automation tasks, including activation of "classic" (i.e. power-hungry) bluetooth to connect to a handsfree set.
On my Xperia Z1 I don't see a way to activate the two protocols independently.
Cheers,
Torsten

Fitbit: Cannot access GPS data on phone -> Update bluetooth library?

Hi,
Maybe someone has an idea: I've want to access my phone's GPS data on my Fitbit Charge 2 - this is not working (normal syncing however is working). The problem seems to be, that my bluetooth library on the smartphone doesn't allow 3rd party app code to access BLE. Is there a chance to update the bluetooth library?

Starting with Android 12, multicasting to a group of BLE audio headphones is supported. How this can be achieved?

Connecting 2 Bluetooth devices at once to your android device and stream audio simultaneously for both of them.
combined audio device routing https://source.android.com/docs/core/audio/combined-audio-routing
in aosp source code page it is mentioned about ble audio supporting multiple audio sink devices.... https://developer.android.com/guide/topics/connectivity/ble-audio/overview
Is there any details on how to achieve this. Please help me on this
The feature is called Auracast. Not everything you'll find in the AOSP is implemented in your firmware. Apart from that this features needs Bluetooth 5.2.
