UseModbuswith your Arduino. Using TCP or RS485 shields, like the MKR 485 Shield. This library depends on the ArduinoRS485 library. This library is based onlibmodbus, modifications were made to the lower level RS485 and TCP layers to use Arduino Serial/RS485 and Client API’s. Then an ...

if (!ModbusRTUClient.begin(9600)) { Serial.println("Failed to start Modbus RTU Client!"); } The board I used was set up to talk at 9600 baud. That might be different for a different Modbus device. Arduino uses 8 bit, parity none, stop bit 1 by default and so does this relay boa...

Once you have the certificates, you can use the ESP32’s built-in WiFiClientSecure.h library to make HTTPS requests. Note that HTTPS requests can take longer than HTTP requests due to the encryption overhead. Also, be sure to use the correct port number (443 for HTTPS) when connecting ...
