Flash nRF52 & RP2040 Devices

Flashing Methods for nRF52 and RP2040 Devices​

nRF52 and RP2040 based devices have the easiest firmware upgrade process. No driver or software install is required on any platform.

Drag & Drop​

nRF52 and RP2040 devices use the Drag & Drop installation method to install firmware releases.

Over-The-Air (OTA)​

nRF52 devices are able to accept OTA firmware updates from a mobile device over bluetooth.

nRF Factory Erase​

You may wish to perform a Factory Erase prior to installing firmware to clear data that may change format and location between releases.

Convert RAK4631-R to RAK4631​

If your device did not come with the Arduino bootloader you will need to perform the conversion.

Use Raspberry Pi as a SWDIO Flash Tool​

If your device can't be flashed through USB or Bluetooth, another option might be a direct SWDIO connection.
