# esp-idf-mqtt-image-client
GUI MQTT client for image display for esp-idf.
I used [this](https://github.com/Molorius/esp32-websocket) component.
This component can communicate directly with the browser.
There is an example of using the component [here](https://github.com/Molorius/ESP32-Examples).
It's a great job.

I use [this](https://github.com/emqx/MQTT-Client-Examples/tree/master/mqtt-client-Electron) index.html.
I use [this](https://bulma.io/) open source framework.
