The controller for the screwdriver uses Modbus protocol to communicate (Ethernet port on the controller). With an Arduino Leonardo and the original Ethernet Shield 2 (controller W5500) it could get this to work.It is a two-way protocol over a TCP channel. The Websocket protocol enables the interaction between a client (the web browser) and a web server (in our case an ESP32 Websocket server). The interesting aspect of this protocol is that it enables real-time data exchange between the web client and the web server. What bothers me the most is that when the ESP32 acts as a server my PC can connect to it and send data from LabVIEW with a simple TCP/IP connection VI. But vice-versa the listener doesn't even accept the client. And if I try to send/receive data between 2 VIs (one as a listener, one as a client), it works without a problem.On ESP32, many people implement manually some sort of watchdog timer using flags and loops. This is NOT how it should be done, especially since ESP32 comes with a hardware watchdog timer.
