let me have a look at this. Maybe there is a missing initialization for older HID devices that we need to handle. Do you happen to have the full btmon binary trace from controller initialization to connection attempt for me?

Are both devices Bluetooth 2.1 or later device that are supporting Secure Simple Pairing? Or is one of them a Bluetooth 2.0 or earlier device?

Regards

Marcel
