help with radioland-china nrf52832 beacon



  • hi guys, i bought a couple of these beacons

    1. is it possible to reprogram them via a jlink?
      2)can you tell me a jlink to buy that is not too expensive?
      I would like to program these beacons with Mycropython or with Espruino.
      3)It's possible?


  • Yes it is possible, using the SWDIO and SWDCLK pads.
    I programmed one to operate with MySensors using a black magic probe, but the J-Link also supports SWD programming.
    The tricky part is connecting to the pads. I just soldered on some wires -- not a very elegant solution, but it worked.

    You can get a reasonably priced J-Link EDU from Adafruit:
