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 don’t work(Service is avaiable but don’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 （Android10）：
ROCKPI 4B
ROCKPI 4C

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

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

Thank you.
I’ll try it.

Hi,
I tried it.

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

I’ll share the log as well.

I’m more inclined to say your phone can’t connect.

#8

I’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 couldn’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

I’m connecting a generic Headset, not a mobile phone.
I’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 phone’s name)

screen_20201015_175211.png1920×1200 63.4 KB

On the other hand, with Jabra’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,
Android10’s image updated?
The headset status didn’t change.
A2DP function turn off by default.

#15

I installed Android 9.0 with pi4b board

However, when you connect your mobile phone to make a call, the board has no sound and does not download the phone books

The Bluetooth logo displayed on the mobile phone is computer

#16

As far as I know, ROCK Pi 4 doesn’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.

#17

I modified the configuration

diff --git a/overlay/frameworks/base/core/res/res/values/config.xml b/overlay/frameworks/base/core/res/res/values/config.xml

     <!-- This device is not "voice capable"; it's data-only. -->
-    <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 don’t know how to modify it so that the sound can be output from rockpi4
