What is holding the connection open is bluetoothd. After closing the file descriptor for RFCOMM, there are two file descriptors in the Bluetooth daemon that are left: bluetooth 1406 root 18u sock 0,7 0t0 26587 protocol: RFCOMM bluetooth 1406 root 19u sock 0,7 0t0 26602 protocol: RFCOMM By terminating the application these go away, but what if I wish to keep the daemon running? How do I tell the Bluetooth daemon to close the RFCOMM sockets?
