MQTT broker running on STM32F7

[CA_SUS]

Hi everyone,

I need to run a MQTT broker on my board powered by a STM32F746. I managed to get the LwIP stack running properly as a starting point. I verified this by sending and receiving topics with the provided MQTT client implementation of LwIP.

LwIP and FreeRTOS unfortunately only provide libs/apps for MQTT Clients.

Unfortunately I can't find a library or similar for a broker in the web and I would like to avoid reinventing the wheel and implement it all by myself. Does anybody know a MQTT broker implementation which I could use (does not even need to be free of charge)? I don't even need the whole feature set of MQTT, a most basic implementation would be sufficient as a starting point.

Thanks for your help!

try to port some Arduino lib (for example ESP32), they use FreeRTOS and lwIP

Thanks for the advice!
