Device Web UI dashboard: STM32 :: CubeIDE :: Bare metal :: HTTP, Websocket, MQTT

[@bennguyen1313]

Could this be done on any processor? For example, the ESP32 IDF IDE has project templates for a simple web-server.. I assume mongoose would replace that tcp/ip stack, but how? I'm interested in serving up a VueJs page from SPIFFS, that uses websockets to push ADC data to all connected clients/browsers as fast as the readings allow!

Yes absolutely you could do it on ESP32. Mongoose can work top on an existing TCP/IP stack - and that's exactly the case for ESP32. Here's an example github.com/cesanta/mongoose/tree/master/examples/esp32/device-dashboard

Perfect!

I want led1 and led2 to light up in stm32 when I press the button by marking checkbox1 and checkbox2 from the computer. How can I make an example about this?

How to implement mqtt?

[@mongoose-networking-library]

Take a look at the video tutorial : kzbin.info/www/bejne/ZmTRnYWHpb-lg5Y Or, generic code example - github.com/cesanta/mongoose/tree/master/tutorials/mqtt/mqtt-client

The struct mip_ipcfg isnt working. It says that everything written in the struct in main.c are no members of mip_ipcfg.

@@mongoose-networking-library I still got a problem. I followed your guide, but I get the DHCP request message. I the pins are correct. Do you know what could also be an issue?
