WebJan 21, 2024 · Arduino ESP32 Serial2 loopback. The working is simple, we write something in arduino serial console and program will echo it. The serial console is connected to Serial (UART0), which is also used for loading arduino code to ESP32. The program will be monitoring UART0, and if it sees any data on UART0 it will write that data to UART2.
