Hello, I am still experiencing difficulties registering a profile and getting BlueZ to call the NewConnection method when a connection attempt is made to it. When I try to connect from another computer, it connects briefly before disconnecting again. I am starting the server with the input plugin removed using: sudo /usr/lib/bluetooth/bluetoothd -P input A btmon log of the session is available at: https://drive.google.com/uc?authuser=0&id=1CgPcEtj1g3Um-1qBuQ8hEImKR28bVmnx&export=download I have looked through the log but there is nothing in there that I am understanding to be an indicator of the issue. I have had some success if I set up the sockets to listen for connections with the code below. However I still don't get the NewConnection method called in the profile I have setup. Any guidance would be greatly appreciated. Thanks, Barry print('Waiting for connections') self.scontrol = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_SEQPACKET, socket.BTPROTO_L2CAP) self.scontrol.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) self.sinterrupt = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_SEQPACKET, socket.BTPROTO_L2CAP) self.sinterrupt.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) # bind these sockets to a port self.scontrol.bind((self.address, self.P_CTRL)) self.sinterrupt.bind((self.address, self.P_INTR )) # Start listening on the server sockets self.scontrol.listen(1) # Limit of 1 connection self.sinterrupt.listen(1) self.ccontrol, cinfo = self.scontrol.accept() print('Got a connection on the control channel from ' + cinfo[0]) self.cinterrupt, cinfo = self.sinterrupt.accept() print('Got a connection on the interrupt channel from ' + cinfo[0])
