ESP32 Forum

Good Evening everyone,
I'm working on a project where ESP32 takes analog data from some senor then send it to a website via
websocket, and then I was introduced to MQTT, i have made the oneshot ADC task and im trying to sent data using a topic called my_topic.

My Questions are,
1- What do i need to know or to read from esp website to get an idea on how to send/receive data?
2- how do i create a dummy MQTT Broker so i can test my clients data?

Thanks everyone

1.) The ESP-IDF MQTT documentation: https://docs.espressif.com/projects/esp ... /mqtt.html

The IDF itself also contains sample code: https://github.com/espressif/esp-idf/tr ... ocols/mqtt

2.) A number of MQTT brokers have publicly accessible test servers. Use one of the to get started, e.g. : https://test.mosquitto.org/
