@kjek If you were using Whitelist, are there other Bluetooth settings you changed too, like Passcode? Maybe you could try booting the Bangle with the button held down (all the way through bootloader, until it starts). That should hopefully boot the Bangle without loading any code at all - and i'd be interested to see if you can keep a connection for longer in that case
