Answer 1

If the pairing is happening as a consequence of your app connecting, I am guessing that some devices will consider it as a temporary pairing and will not keep the device in the paired list after the connection is disconnected. To retain the device in paired list you should manually pair through the Bluetooth settings menu. Once paired your program can connect / disconnect and the device will retain itself in the paired list.
