• Hello there, and sorry to re-open the discussion.

    When I set my bangle in DFU mode (hold BTN1 + BTN2 until it reboot, and release before the === line is complete), I can see "DfuTarg" bluetooth device in my bluetooth discovery app (laptop and mobile).

    When I select it, the watch displays "Connected", and a couple of seconds after, says "Disconnected".
    On the laptop/mobile side, the bluetooth app says it could pairing was rejected.

    I am pretty annoyed, because my previous attempt to upload a new Firmware failed before completion, and the watch can not boot any more...

    What does it mean 'when I select it'?
    You should not use laptop app/browser and should not 'pair it' in this mode.
    See https://www.espruino.com/Bangle.js#firmw­are-updates for the procedure.
    There is nrfConnect or nrfToolbox app for Android to do this DFU update.
