[PATCH BlueZ v8 8/8] core: Suspend scanning before connect on pairing

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

 



If there is a disconnected bonded device there will be a scanning
procedure active due to the General Connection Establishment Procedure.
This scan have to be suspended before trying to connect to the remote
device for pairing.
