Re: Is there a way to have ESP32 send its logs to a web server?

I used the MQTT client to send log prints to a broker on the network. It works very well and can handle a ridiculous number of prints per second.

Re: how to run Modbus RTU On ESP IDF

Hi, I would like to use modbus function 6 for write single holding register, so how I can do this with modbus library? Because it uses function 10 for write multiple registers, and my device doesn't recognise this function.
