Hi there!
I have some custom boards for BG95M3 & BG96.
Unfortunately I do not have access on the Modem serial port.
There is: USBport-Arduino-QuectelModule
My idea is to make a bridge between Arduino serial and modem serial in order to update the firmware on Quectel.
Do you have some examples? Until now I can make the pass through in order to deliver normal AT commands, but no Firmware update.
Unfortunately for the moment I have to reset somehow the serial connection on BG95 because O have set 9600 baud and I cannot connect with it anymore
