Hello,
after some time of error-free working with Arduino IDE 2.0.3 and my RAK3172 board I am now getting an error message “Detect baudrate fail, can not get the baudrate”. The selected COM port is available when I open it in a terminal program but the module also does not respond to any AT command. This suddenly occurred after uploading some Arduino code. I suppose the module “hangs” in a loop or something like that.
I already uploaded the module firmare using STM32CubeProgrammer via JTAG but this didn’t help. The arduino code is probably stored in another address range.
Is there a way to reset the module completely to its factory settings including the Arduino code?
Best regards
Jan
