ESP32 Forum

Hi all!

Newbie question
I have:
1) MQTT FX on my pc as a broker;
2) ESP32 on AP mode running Arduino Core and PubSubClient;

How can I send data from PC to ESP ( and viceversa ) ?

Help needed

Thanks in advance!

Easy: Use MQTT on your ESP32.

You will find that there are MQTT libraries for ESP32 with examples, ... You will find tools bundled with the broker for: command line publish, subscribe. You will find support for MQTT for Java and many other languages for your PC.

On your ESP32 you will need to enable STA mode too (AP + STA).

Also easy: Google + Search this forum.
