We provide users with hex files, which users can find in the open source project Doc

folder.

However, it should be noted that using the DFU function of the nRF, unlike the

previous firmware programming method, the bootloader firmware must be programmed.
Therefore, three firmwares need to be programmed to use the DFU function. They are the
Bluetooth protocol stack firmware, the DFU application firmware, and the bootload
firmware. Bootload firmware can be found in open source functions.

For details on how to program the Bluetooth protocol stack and application firmware,

see:

RAK815(RAK813 BreakBoard) Firmware download manual.

The following figure shows how to program bootloader firmware:
