When working withESP32 WiFi/Bluetooth MCUunderArduino SDK for ESP32, you will notice thatSerialwork just fine. ButSerial1andSerial2do not.ESP32has 3hardware serial portsthat can be mapped to almost any pin. But,Serial1andSerial2will not work. In case of ESP32 this just has to be done ...
I am working on a project with an ESP32 and a GPS. In a number of examples found, people use the hardwareserial.h library. Despite my research in different places, I was unable to find where to download this library. Can you tell me how to do it?

(I use the SimpleModbusMaster library in Arduino) The first packet with the ESP32 is processed correctly but the Siglent reveals that all packets after are the first reply nonsense. I assume Serial.flush() causes the issue. I've found some usefull threads but I have not distilled a working...
There are three hardware supported serial interfaces on the ESP32 known as UART0, UART1 and UART2. Like all peripherals, the pins for the UARTs can be logically mapped to any of the available pins on the ESP32. However, the UARTs can also have direct acc
I am new to ESP32 development, so please excuse my newbie questions. I have the ESP32-C3-WROOM-02 development board. I can flash sketches and can see the debug info on serial monitor. When I try to connect a serial device (GPS) to the RX and TX pins, flashing does no longer work...

This library, a wrapper around ESP32 ledc library, enables you to use Hardware-based PWM channels on ESP32, ESP32_S2, ESP32_S3 or ESP32_C3-based boards to create and output PWM to pins. Using similar functions as some other FastPWM libraries, it enables
