Sending STM32 MCU Firmware Over the Air to Quectel BC65 NB Modem

Hello Quectel community,

I am currently working on a project where I have a Quectel BC65 NB modem connected to an STM32 MCU. I want to send the firmware of the STM32 MCU to the NB modem over the air. Could you please provide guidance on how I can achieve this using the Quectel BC65 NB modem and any relevant protocols or methods? Any example code or references would be greatly appreciated.

Thank you in advance for your help!

Is your goal to upgrade the mcu?
