Conlicts in the pinout documentation in the User Manual.

Postby vapisoft » Mon Dec 25, 2023 11:54 am

I want to use the ESP-AT project.
In their user manual, in Table 2: ESP32-C3 Series Hardware Connection Pinout
GPIO6 (RX)
GPIO7 (TX)
GPIO5 (CTS)
GPIO4 (RTS)
But, the pinout in the ESP32-C3 are:
GPIO20 (RX)
GPIO21 (TX)
So I don't understand what is right and why there is this difference.

There is no conflict or difference. ESP32-C3 AT uses two UART ports: UART0 is used to download firmware and log output; UART1 is used to send AT commands and receive AT responses.
