What are the reasons for Bluetooth to become disconnected or unpaired? I'm using a Fender PA system paired with a Windows 10 laptop which has a music playing program. After a couple of songs, the pairing fails, and I have to re-pair the two devices. BTW, the 2 devices are within 2 feet of each other, so distance is not the problem. Do I need to strengthen the Bluetooth signal, if that's even possible?
