BT can’t work after flash jetson tx2 with jetpacke4.3, no BT speaker and keyboard

Hi andylu_hust,

Confirmed BT is working on JetPack-4.3 (r32.3.1).
Please check BT connection from “All Settings -> Bluetooth”

我使用的系统是jetpack4.3,小版本号我不知如何查看,系统为近一周内安装的 , 更新后现在已经能连接到蓝牙键盘和蓝牙音箱了, 但是连接蓝牙音箱后播放音乐或视频,没有声音,声音设置中,蓝牙设备的音量控制为灰色,不调节。当 在声音控制中,将输出设备设置为 hdmi 时,音频、视频可以继续播放,当选蓝牙音箱设备为输出时, 音频、视频停止不动,不能继续播放。

Hi andylu_hust,

Could you write your question and comment in English on this forum?

The system I used is jetpack4.3, and I don’t know how to check the small version number. The system was installed within a week. After the update, it can now be connected to the bluetooth keyboard and bluetooth speaker. When the output device is set as hdmi in the sound control, audio and video can continue to play. When the bluetooth speaker device is selected as output, audio and video stop and cannot continue to play, no sound

Hi andylu_hust,

Please following below steps to enable BT audio:

1. Navigate to the following file:
   $ sudo vim /lib/systemd/system/bluetooth.service.d/nv-bluetooth-service.conf
2. Search for below line:
   ExecStart=/usr/lib/bluetooth/bluetoothd -d --noplugin=audio,a2dp,avrcp
3. Remove all options for no plugin. It should look like below:
