Hi - you'll need to connect to the device called 'DfuTarg' that appears. If it's connecting to
Pixl.js ...as it seems to be in the screenshot, that's the device's name when it's not in DFU mode.There's a bit more info about exactly what steps you need to follow here: http://www.espruino.com/Firmware+Update#nrf52
