This uses the BSA AV API to send a vendor control command: ctype=0x3, label={counter which is incremented}, length=0x9, data=[0x31, 0x00, 0x00, 0x05, {u8 [[#AvrcEventType]]}, {rest is zeros}]. | |||
This does nothing since BSA requires [[#EnableBluetooth|features]] bit1 and bit3 to be set in order to use this. | |||

This uses the BSA AV API to send a remote control command: label={counter which is incremented}, rc_id=[[#AvrcOperationId]], key_state=[[#AvrcStateType]]. | |||
