[PATCH BlueZ 1/4] android/AVDTP: Make signalling channel priority 6

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

This makes signalling priority 6 so it can push commands before the
stream channel, without this the stream channel may be schedule
first and cause the signalling commands to timeout while waiting a slot.
