Does android 5.0 support HFP client (act as Headfree client devices by Bluetooth)??

[Yong Ma]

Dear all,

    I found a config value in packages/app/Bluetooth/res/values/config.xml  and a hide class

1. <bool name="profile_supported_hfpclient">false</bool>
   
2. android.bluetooth.BluetoothHeadsetClient, this provides HFP client API, such as dial, accept call.

    I set profile_supported_hfpclient to true, and remake and flash the system.  I write a test app to  using BluetoothHeadsetClient API, and it can dial and accept call. However, the voice is not working when calling. The speaker doesn't make sound, and the voice received by mic  isn't transferred by Bluetooth SCO.

    So does android support HFP client fully? How can I make voice works well？？

Hi,

I am currently porting hfp client from android 5.1.1 back to android 4.2.2, and I have successfully added and modified the needed source files related to the bluetooth hfp client. Just like you, it can dial, accept and terminate calls, but I can hear no voice during calling. Maybe the audio part needs porting too...

So have you find a solution to the 'no sound when calling' problem? If yes, can you share the solution with me?

Thanks!

Hi,

I am currently also trying to enable the A2DP Sink and the HFP Client. Currently the A2DP Sink is working and I can also connect to the HFP Client but if I make a call or if I execute connectAudio audio stops working.
So the problem maybe someting about the SCO connection (used by HFP) because A2DP is working.

Is there already a solution?
Please share your solutions if you found something out.

Thanks!

Hi,

Could you please tell me the steps followed? I googled a lot but no proper documentation is found.

 Dear Sir,

 I am totally new to the app development and just started to learn how to create it, but would like to create HFP client app
 (Control In/Outbound call and get call history from paired device).

 I just found your thread and am eager to dial / accept call using the hfpclient.
 I have read through all the documents of BluetoothHeadsetClient and Android developer page, but I could not quite get how to control it.
 So I tried to find out the xml file you mention in this thread < packages/app/Bluetooth/res/values/config.xml> but I am unable to find out.
 Is it inaccessible for un-rooted user?
 Or is it at somewhere inside the Android Studio ?
 
I am using;
Android Studio Ver. 1.5.1
Device : Un-rooted Xperia Z3  with Android OS : 5.0.2

I know this thread is passed over 1 year but hope to get some answer from you guys.

I apologize for interrupting you for my ignorance in advance.

Regards,

Hy,

By default, Android cannot act as HFP Client. This functionnality is not compiled in the ROM.

Sorry, but I think you won't be able to use the HFP Client API on a standard phone without a custom ROM.

Morover, you will need to do some changes in the sound driver and the bluetooth stack to be able to act as an HFP Client.

Hi Thomas!

I have also got HFP client working on Lollipop, but for some reason I can't hang up calls. terminateCall() doesn't work with iPhones because its part of the Extended Call Control spec, which iPhone doesn't support. And it doesn't seem like there's any way to just send a normal hang up command. Did you encounter this?

Can you hear a sound after you accept call ? Could you share what have you changed in ROM ? 

Thanks .

I have the same problem, that was A2DP sink work well and no sound in HFP client.

Have you got the solution for this issue?

We are facing the same problem , We are using a Nexus shamu device running on Noughat. Enabled the A2DP sink and HFP client in the config.xml and AUDIO_FEATURE_ENABLED_HFP in the device specific mk file but sstill no sound while attending calls through HFP. Any help will be appreciated

Hello, I just studied Bluetooth development, also need to do a app to answer, refused to answer the phone, I can not obtain BluetoothHeadsetClient. Can you show me how you get Bluetooth headset client?

Thank you very much.

A2DP works on SBC codec (as of classic Bluetooth, can support MP3, AAC also based on your implementations), whereas HFP/Headset works on SCO backed by PCM audio channel.

Hi, did you port the a2dp profile too? I`m trying to port a2dp sink to 4.2.2 can you share the result?

Hi,

You say you enabled A2DP sink and it is working. Is this for Lollipop? Do I need to make only these changes?

i) In external/bluetooth/bluedroid/include/bt_target.h (false to true):

/* Enable bluetooth av sink. */

#define BTA_AV_SINK_INCLUDED  TRUE​

ii) platform/packages/apps/Bluetooth/res/values/config.xml (false to true):

<bool name="profile_supported_a2dp_sink">true</bool>

OR i have to make <bool name="profile_supported_a2dp">true</bool>  which is already true , false so that it works as only a2dp sink?
