Put your module into DFU mode

  1. Power off the module (or power down the case).
  2. On the back of the module, change the jumper position to UPDATE MODE.
  3. Connect the module to this computer with a USB cable.
  4. Power the module back on. The module is now in DFU mode, its normal firmware won't be running, and no panel LEDs/audio activity is expected.
