imx8mm board to be a bluetooth speaker

[xj916ch]

Hi,

I have an imx8mm board with a better loudspeaker.

The board bluetooth functionality is fine, it could be paired with my phone. 

While, How do I set it to be a bluetooth speaker? just connected to my phone, and music from my phone to the board loudspeaker?

Hello,

Besides the comment that Radhika made. Make sure that your device is being set as a2dp_sink profile. To set it, use the following command:

# pactl set-card-profile <Your Bluez card name or number> a2dp_sink

Best regards,

Diego.

Hi Xin Jian,

Set the default source as a bluetooth and audio jack (On which the loudspeaker was connected) as a default sound card.

You can follow the below steps after pairing and Connecting your phone using bluetoothctl with i.MX8m mini

1.       cat /proc/asound/card (to list number of sound cards)
2.       aplay -L (to list available output sinks)
3.       pactl list short sinks  (for name or index number of possible sinks eg. )
4.       pactl list short sources OR pactl list sources  (to list available sources)
5.       pactl set-default-sink 1 (to set default sink id as a default id of loudspeaker - in our case it is 1)
6.       pactl set-default-source 6 (to set default source id as a default id of bluetooth source - in our case it is 6)

Verify that your phone is connected with the board using bluetoothctl before playing the music.
