The STM32 family of 32-bit microcontrollers based on the Arm® Cortex®-M processor is designed to offer new degrees of freedom to MCU users. NPE X2 is a lightweight, but powerful energy-efficient and fully capable automation controller series. No one has replied C. Test with the ws4py library from a Raspberry Pi 3. com/pyserial/pyserial docs: https://pyserial. Since the ESP8266 module has a serial port, we used the softwareserial library to create a second port that would be used only for Modbus RTU allowing programming and debugging without physically interrupting the modbus communication, we added an integrated MAX232 for protocol conversion to RS232. Digi Xbee Cellular 3G Module and Remote Server via MQTT. Recommended References. Hello Frank, I am interested in getting Modbus functionally from the ESP8266, can you share your code ? thanks, aniston.
