Thanks Pierre for your suggestion. I have one more question. If I open RFCOM socket connection, connect with another device, then close that RFCOM socket, Will bluetoothd remove all the pairing information from the linkkeys file or not. Because When I close RFCOM connection pairing information is getting lost, I would like to know weather it's a common or am I doing something wrong?? Your suggestion would be a great help for me.. -- 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
