2.Firmware Upgrade
In order to facilitate the user to upgrade the device firmware, we have designed a
BOOT upgrade mode for the device. The user can upgrade the device directly using the
UART interface. The BOOT mode essentially adds the code to receive the rewrite
firmware at the start address of the device's RAM. After the device upgrade is complete,
jump to the application's address to run.
This module provides two firmware: AT command firmware and open source project
firmware.These two firmware upgrades’ methods are described in detail below.

2.2 Open Source Project firmware download
The application firmware of the RAK_LB801 device is a firmware compiled using
open source code provided by RAK:
https://github.com/RAKWireless/RAK811_LoRaButton
However, the bin file directly generated by the open source code compiler cannot be
upgraded through BOOT. You need to use the RAK_LB801 LoRaButton Firmware
Generate Tool.exe to convert it to a bin file that can be upgraded by BOOT.
After successfully compiling with open source project, the generated
rak811_lorabutton.bin file and RAK_LB801 LoRaButton Firmware Generate Tool are
placed in the same directory. Click on the Run tool to generate the
u_rak811_lorabutton.bin file. This file can use BOOT mode to upgrade the firmware.
