The 2.3 documentation notes : General AT commands can be used quickly
The USB UART0 shows debug data but does not responds on AT commands, also not after sending "+++" command
Generic ESP32 expressif seems to point to using UART1 (GPIO9 and GPIO10) for AT commands but I have not found any referenced Pin numbers exposed to the ESP32-A1S devboard

How can I send AT commands to the board?
