I used two Arduino UNO boards, Two Arduino Ethernet Shields. Use Arduino IDE for ESP32 to compile and upload it to the ESP32. The Rx/Tx are relative to the ESP device. Open a TCP over Serial connection to a server from the Arduino using the host. What I wish to do is to simply receive a TCP/IP string, process it, then send back another string, like I always did with the Ethernet shield together with its Ethernet library. On the router side; however, I am stuck trying to verify if data that is sent to the serial port gets broadcasted out via WiFi signal. Identify the IP address of the router or network adapter that the Arduino Ethernet Shield is connected to. As part of this WiFi connectivity, I have set I'm currently using an ESP32 under Arduino IDE to generate and send 33 bytes of data via WiFi (TCP Packets). Some years ago I have read a little bit about it. I will send commands and receive updated status reports. You can adjust settings through web interface. So far, I can sent and receive a string via serial (VB on PC-side). With this setup, the Arduino will read data from a serial RS485 interface and transmit it to a TCP server, either within the same local area network (LAN) or remotely over the internet. It is commonly used in industrial electronic devices, such as Building Management Systems (BMS) and Industrial Automation Systems (IAS). Even if you would say bad or "hard" path I'm pretty sure this would give the very big overview. I have a custom board with Atmega2560 and w5500. In operation the serial port is That means, it can connect to a TCP server via Ethernet network.
