I do not have any example of using the test.mosquitto.org. However, here is a tutorial on Sending Data to Cloud with ESP32 and ThingSpeak.
https://www.theengineeringprojects.com/ ... speak.html
ThingSpeak is an MQTT server. ThingSpeak updates various ThingSpeak channels using MQTT and REST APIs.Professionals in the industry also use the platform to analyze and chart numerical data sent from smart devices and stored on various channels. Business owners can update their feeds, clear, or delete their channels entirely by using REST API calls like POST, GET, DELETE, or PUT. MQTT Publish methods allow users to update their feeds, whereas MQTT Subscribe methods allow them to receive messages.
