ESP32 Forum

I am shifting my project platform from ESP8266 to ESP32. The Modbus RTU read and write via Software serial worked fine with esp8266 using modbus-esp8266 library and as per the documentations I guess this library must work with ESP32. But it causes compilation errors as shown below:

E:\AMAL\micredge\iiotnext-edge\Code\main\modbus_driver_2.ino: In function 'void BeginModbus2()':
modbus_driver_2:79:41: error: no matching function for call to 'ModbusRTU::begin(SoftwareSerial*, int, int)'

Any solution for this issue is much appreciated.
