OSD BT pairing screen becomes unresponsive

[betsyheaven]

Pressing F11 on keyboard on MiSTer OSD brings up the Bluetooth Pairing screen.
Bluetooth Pairing screen sometimes get stuck waiting for a new Bluetooth connection.
Currently connected devices no longer control this screen; not able to press anything on the keyboard to exit out of this screen, and need to reboot.
Only occurs sometimes. Sometimes I can exit out of this screen without problem. Sometimes it will be stuck waiting for a new connection. Not sure what the variable is here?

It probably because of buggy BT dongle.
I use BT often and have no such problem. Try to move BT dongle to other USB port. Remove other USB devices while testing.

It's just primarily the "BT Pairing screen" that seems to get stuck, as if it is waiting for a new connection to be paired.

In general use, I can connect to BT USB devices without issue. I don't often have to create new pairings because the BT always remembers the established connections and I can use BT without issue. It's specifically just the "BT Pairing Screen" that gets stuck, waiting for a new connection to the paired, and the established BT connection is not able to exit out of this.

I've tried using multiple BT devices. I primarily use a ZEXMTE USB Bluetooth Adapter, but also have the same issue with the 8bitdo Keyboard when connected to the 2.4g USB adapter. I've also tried removing all other USB devices while testing and still having the same thing. Consistently getting stuck on the BT Pairing Screen.

Not sure how else to troubleshoot this or test further.

It's possible there is some BT device nearby or interference with other wireless systems (like WiFi, RF, Zigbi).
