Firmware update of BG96 RAK8212 moudle via DFOTA
Quectel provides a method to update the firmware of BG96 via DFOTA (Delta Firmware Upgrade Over-the-air). And it is a simple way as below:
Make sure your moudle has connected to operator net, you can query by the relevant AT commands are listed below:
Query signal quality: AT+CSQ
Query network registration status: AT+CREG? or AT+CGREG?
Query the registered operator: AT+COPS?
My test is based on 2G with China Mobile, and my init code is shown in the attached file.
Put the delta firmware on HTTP server
Execute AT+QFOTADL command. Then the module will automatically download the package from HTTP server via LTE/GPRS network and finally automatically upgrade the module’s firmware.
4.Use command :ATI to see the firmware version. For example, the response like below:
0> Revision: BG96MAR02A05M1G (05 is the version num)
The overall process:
- moudle connect to operator net
- put firmware on http server and the address is like : https://www.quectel.com:100/update.zip
