Hello,
I was using a esp8266 earlier, but now I have started using a ESP32-S3-WROOM-1. My RX and TX pins are on pin 37 and 36 respectively. (PFA image for reference.) I can confirm that the board is working fine but none of the data from the pixhawk is being shown on the serial monitor on arduino ide. I believe the rx and tx pins are the problem. Can someone give me a technique to code using cpp or give me a solution to this problem?

Re: Mismatched RX and TX pins
If you swap the TX and RX pins, are you being able to establish the USART communication?

Re: Mismatched RX and TX pins
Please inform the name or model of your ESP32 S3 board.
See what is written on your board - TX and RX on the top right side. These are the UART pins.
In the case of the ESP32 S3 DevKit, these pins are used to UART:
