it is posible to send Just image/data via wify without displaying them on a browser ? I want to send images to à Rpi via wifi, but thé httpd example are ment to show images on a Web browser only
Here is a fairly basic MQTT example for Arduino-compatible devices.
- USR-TCP232-T2 and MQTT
- Web UI remote control ESP32-CAM with JavaScript MQTT Client project
- PubSubClient Issue: Sending message with length above 16377 bytes fails on ESP32

Trying to integrate to HiveMQ, need to parse URL to ip
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.

PlatformIO vs. Arduino: different results
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.

Can client know whether it is a retained message or not?
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:
espMqttClient
- esp32 disconnects repeatedly
- ESP 32 receives messages very late and connection gets interrupted sometimes
- ESP32 stops subscribing after a while

MQTT 5 protocol on ESP8266 devices?
I created my own library for ESP8266 and ESP32 (https://github.com/bertmelis/espMqttClient) and decided to stick with 3.1.1

Updating firmware for multiple ESP32 devices at once
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
