- don't try to start BT in the background. you can only start/stop a BT server once, else new connections don't work - be more mindful of reading/writing bytes from the input/output streams... make sure bytes are available, because you will block forever if you do not do that - use the device class tag to filter devices in discovery instead of the fdroid name tag - this now successfully connects but there is an error in the certificate fingerprint verification still
