In case of PA we do wait for Audio.Connected property before loading the module which does call MediaTransport.Acquire, but 2 seconds is too much there might be something else holding the setup, do you reply right away the SetConfiguration, if you do try to Acquire while bluetoothd is waiting you to reply it might fail. > bluetoothd[751]: audio/avdtp.c:avdtp_parse_cmd() Received OPEN_CMD > bluetoothd[751]: audio/a2dp.c:open_ind() Sink 0x2a0d40a8: Open_Ind > bluetoothd[751]: audio/transport.c:media_transport_acquire() Transport > /org/bluez/751/hci0/dev_00_17_E3_3B_4F_DD/fd1: read lock acquired > bluetoothd[751]: audio/transport.c:media_transport_acquire() Transport > /org/bluez/751/hci0/dev_00_17_E3_3B_4F_DD/fd1: write lock acquired > bluetoothd[751]: audio/transport.c:media_owner_create() Owner created: > sender=:1.40 accesstype=rw > bluetoothd[751]: audio/avdtp.c:avdtp_ref() 0x2a0d2a00: ref=3 > bluetoothd[751]: audio/transport.c:media_transport_release() Transport > /org/bluez/751/hci0/dev_00_17_E3_3B_4F_DD/fd1: read lock released > bluetoothd[751]: audio/transport.c:media_transport_release() Transport > /org/bluez/751/hci0/dev_00_17_E3_3B_4F_DD/fd1: write lock released > bluetoothd[751]: audio/transport.c:media_owner_free() Owner :1.40 > getting the reply from the cb failed > GDBus.Error:org.bluez.Error.NotAuthorized: Operation Not Authorized Strange, if what you said is true why there is no "SEP in bad state for resume" error? Anyway I think we can fix this by checking the current state of the SEP and waiting it to go OPEN to resume, so the client don't have to keep tracking of Audio.Connected. -- Luiz Augusto von Dentz -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
