问题
We made a custom board which has Android 7.1 operating system as a our custom board must act to a reciver with bluetooth(while a2dp sink profile in bluetooth can do this), but we have do many works over weeks on it , but it still not work, so i'd like to ask somebody who know or had similar expirence on it could help. Android 7.1 used the fluoride Bluetooth stack
our works :
1. packages/apps/Bluetooth/res/values/config.xml
<bool name="profile_supported_a2dp">true</bool>
<bool name="profile_supported_a2dp_sink">true</bool>
2. android/platform/system/bt/include/bt_target.h
#define BTA_AV_SINK_INCLUDED TRUE
Android device as a receiver for A2DP profile, but it seems didn't work.so anybody could help.
I didn't check with
<bool name="profile_supported_a2dp">false</bool>
If both a2dp profile role like source and sink are enable then it will take default as a a2dp source instead of a2dp sink ?
So that's why its not work?
