I have recently started development on esp32 using esp-idf. Apart from micropython ,are there any libraries/support which can be added to esp-idf components for Modbus master (RTU and TCP/IP) same here. Just found modbus RTU slave in IDF, is there any master implementation availible?aless...
The ESP32 WiFi can run in one of the following modes: WiFi Station, Access Point, or Both at the same time. There is an additional mode called Promiscuous mode in which the ESP32 will act as a WiFi sniffer. The ESP32 Library does support the first 3 modes by default. To set the ...
