"ble_uart" : Unhandled promise rejection

Tue 2021.09.07

It appears that the error may be caused and thrown from within the disconnect() function at L15

http://www.espruino.com/Reference#t_l_BluetoothRemoteGATTServer_disconnect

function BluetoothRemoteGATTServer.disconnect()
Returns: A Promise that is resolved (or rejected) when the disconnection is complete (non-standard)

See Note: 'In Espruino we return a Promise to make it easier to detect when Espruino is free to connect to something else.'

That said, I thought it would be a breeze to add detection code, but code location and the syntax is a bit different with nested functions.

Maybe this might provide some clues:
