Prerequisite steps

  • Connect the Icarus board to the nRF9160-DK using the TagConnect
  • Power the Icarus board (USB, battery or VIN)
  • Make sure the voltage switch on the nRF9160-DK is set to 3V

Update firmware

Note: It is advised to switch the button on your nRF9160-DK to nRF52 instead of the nRF91 to make sure you get an error if something goes wrong and the modem firmware does not silently go to the modem on the nRF9160-DK.

  1. Start the nRF Connect for Desktop application and launch the "Programmer" module

  3. Click the "Update modem" button on the bottom right side of the application and select the firmware file you downloaded

    Click "Update Modem"
    Click "Update Modem"

  4. Click "Write" on the window that opens to start the firmware update process

    Click "Write Firmware"
