BG95 M3 Updating firmware via uart main

Hi, I want only gsm communication over bg95 M3 . Can I do firmware updates via main uart?I don’t want to use USB.

Hi Melihkiyi1:
If you want to upgrade through UART, you can use DFOTA method.
You can refer to the document in the link below:

Which uart pins should I use to use the DFOTA method? (
debug or main or gnss)

The main UART. But please note that Delta package need to be obtained from Quectel technical support.
Please contact your local technical support.

thank you for answering my questions

You are welcome.Wish you all the best.
