espMqttClient VS pubsubclient

I created my own library for ESP8266 and ESP32 (https://github.com/bertmelis/espMqttClient) and decided to stick with 3.1.1

I made an MQTT lib that is capable of OTA over MQTT. I use it myself. Code sample in the repo: https://github.com/bertmelis/espMqttClient/tree/main/examples/ota-esp8266

I am trying to capture current readings in a bulb and send them over mqtt to aws cloud using this library https://github.com/bertmelis/espMqttClient and the example in it: https://github.com/bertmelis/espMqttClient/blob/main/examples/tls-esp32/tls-esp32.ino

If you're used to the async lib, try this: https://github.com/bertmelis/espMqttClient

If you're after example code, take a look in https://github.com/knolleary/pubsubclient/tree/master/examples

Here is a fairly basic MQTT example for Arduino-compatible devices.

Have a look at this example.

What do you mean pubsubclient.h doesn't accept URLs as argument? Check out this example. You can change the mqtt_server variable to be whatever the hivemq URL is.

On Arduino, the most used library is pubsubclient

I'm using v 2.8 of Nick O'Leary's pub/sub client (https://github.com/knolleary/pubsubclient). Other libraries are what gets installed from the install of the toolchain. In the case of Arduino this is apt install arduino on Debian and installing the PlatformIO toolchain via the VS Code extension installer.

I am using this MQTT client library for Arduino/ESP, and its API is like this page. The callback function for message reception event is like the following:
