Device Firmware Upgrading

If the firmware version of your RAK5205 WisTrio LoRa Tracker is newer than V3.0.0.0 or you have just burned the bootloader into RAK5205 WisTrio LoRa Tracker according to the Burning Bootloader into the Device section, you just need to burn the upgraded firmware according to the following steps now:

1.First, type the command to let the RAK5205 WisTrio LoRa Tracker work in boot mode.


Note If you have just burned the bootloader by yourself according to the section 2, it works in boot mode now. If the current version of the RAK5205’s firmware is newer than V3.0.0.0, you need to set an AT command <at+set_config=device:boot> to let it work in boot mode

2.Choose the correct COM port and set the baud rate to 115200. Then open the serial port and enter the AT command <at+set_config=device:restart> to restart.
