Send command to ESPEasy via UDP.

[Aria James]

Yep, ESPEasy can receive UDP commands, so you should be able to send them from your PLC without any issues. Just make sure both devices are on the same network and UDP is enabled in ESPEasy. I’d recommend testing it first with a simple UDP sender tool before setting it up fully.

Have you read this thread?
That was solved half a year ago.
Now we are looking for a solution for uart to UDP.

I have done some improvements to P020 - Serial Server in PR #5287

This should at least improve the handling of TCP -> Serial pass through, and when receiving via serial it can now generate an event with the data converted to hex string, as usable by the SerialSendMix command.

Also added a serialsend_test command to test event processing more easily.

Here's an ESP32-C3 Collection A build for testing:

Thanks for the info.
I will test and report back.

I have another feature for you to test: Pass-through from UDP to Serial
Available in this build:

You can select to have TCP (Default), UDP or TCP & UDP handling. UDP will only pass all data received on the configured port (same port is used for both TCP and UDP) to the Serial port.

Please report your findings
