Where do I adjust the baud rate that the ESP-AT uses (UART)?

I know there are 2 different sets of R/W - I am not talking about the actual ESP32 console - I am talking about changing the speed from 115,200 on the serial PINS that the ESP-AT code is using, down to 38400 or 57600.

I'm no expert, but I noticed these while trying to sort my own issues. Have you seen these pages?

It looks like that would require a recompile/flash to change

This one looks like it is explaining how to modify a config-type file. I'm assuming you would just need to update the one partition.

The default baud rate used by the AT command port is 115200. You can refer to https://docs.espressif.com/projects/esp ... .html#id11 to modify the uart_baudrate field, which is defined in factory_param_data.csv file.
