Bluetooth headset supported?

#1

Hello,

I checked Bluetooth headset profile on rockpi4 android9.
Now, Bluetooth headset service not running.

Because, headset settings is disabled by overlay settings.

    device/rockchip/common/overlay/packages/apps/Bluetooth/res/values/config.xml
 <resources>
    <bool name="profile_supported_a2dp_sink">false</bool>
    <bool name="profile_supported_hdp">false</bool>
    <bool name="profile_supported_hs_hfp">false</bool>
    <bool name="profile_supported_hfpclient">false</bool>
   ...

I tried to test by custom build image with above change settings( false -> true ).
But Headset donā€™t work(Service is avaiable but donā€™t work).

Has it been disabled for some reason?

In a different thread, the Radxa Team says that the BT Headset Profile is not yet supported.

Hi
Please test the following firmware ļ¼ˆAndroid10ļ¼‰ļ¼š
ROCKPI 4B
ROCKPI 4C

Open Bluetooth Sink:
enable : TunerSettings -> Bluetooth -> Bluetooth Sink.

If Wait... dialog not dismiss, you can enable bluetooth in status barļ¼Œ or reboot rockpi4.
You can pair Rockpi on your phone and play music to Rockpi, which will play audio via HDMI.

Thank you.
Iā€™ll try it.

Hi,
I tried it.

As a result, the BT devices can be paired, but they are disconnected shortly thereafter.

Iā€™ll share the log as well.

Iā€™m more inclined to say your phone canā€™t connect.

#8

Iā€™ll try again and take the logcat.

I have re-filed the log.
The situation is that the Headset device has been deleted once, paired again, and then connected and disconnected repeatedly.
Just to be sure, I launched the recording app and ran it.

#9

I couldnā€™t find any useful information, I tested phones from all three brands that could play music properly. What device do you use.

#10

Is it a Headset Profile?

#11

Sure, Headset Profile

#12

Iā€™m connecting a generic Headset, not a mobile phone.
Iā€™m trying it out by connecting my Jabra Talk v2.

https://www.jabra.com/bluetooth-headsets/jabra-talk2

Note that when I paired the handset, I could hear the sound on the phone with the RockPi4C.
(Banana20 is test phoneā€™s name)

screen_20201015_175211.png1920Ɨ1200 63.4 KB

On the other hand, with Jabraā€™s Headset, when paired, the profile shows nothing like the one below and is immediately disconnected.

If you use a mobile phone to connect to Bluetooth, please turn on the A2DP function, otherwise please turn off the A2DP function.
A2DP: TunerSettings -> Bluetooth -> Bluetooth A2DP.

#14

@Shine Hello,
Android10ā€™s image updated?
The headset status didnā€™t change.
A2DP function turn off by default.

#15

I installed Android 9.0 with pi4b board

As far as I know, ROCK Pi 4 doesnā€™t support the BT call feature because of the hardware limitation. The I2S is not routed to the wifi/bt module. BT speaker is supported.

I modified the configuration

project device/rockchip/common/ 
diff --git a/overlay/frameworks/base/core/res/res/values/config.xml b/overlay/frameworks/base/core/res/res/values/config.xml

-    <bool name="config_voice_capable">false</bool>
+    <bool name="config_voice_capable">true</bool>

At present, the interface for making calls from mobile phones can be displayed.
I donā€™t know how to modify it so that the sound can be output from rockpi4
