In terms of API, it will be very similar to the regular Serial communication functions we use on the Arduino environment. Note that the example provided here is based on the libraryexampleavailable on the Arduino core, which I encourage you to try. ...
Now, in order to establish the serial communication with the ESP32 over Bluetooth, we will need an additional serial monitor, so we can send the data to the device. Although we can open a new instance of the Arduino IDE and open a new terminal for the Bluetooth emulated COM port, I’...

Initializing ESP32 UART in Arduino IDE We use the HardwareSerial library when working with ESP32 UART communication using UART1 or UART2 ports. So, firstly include the library in the script. #include <HardwareSerial.h> Next, if we use Serial.begin(), then pins 1 and 3 are used, which...
Modbus-RTU (Remote Terminal Unit) meansthat the Modbus protocol is used on top of a serial line with an RS-232, RS-485 or similar physical interface. It is point to point communication which means it has only one master and slave. Modbus RTU is using binary coding and CRC error checking...
