CLI hangs on MacOS (after BLE transfer)

[mgjm]

I've tested this now on macOS where writing to the badge works but afterwards the CLI just decides to hang indefinitely and not exit as expected. USB works flawlessly :)
I will be able to look into the hang issue after writing on macOS and test on Windows sometimes in the beginning of next week.

Hanging only affects BLE, with USB it exits normally as expected
