need a simple MQTT client for stm32f446 with no OS

Posted by illidan1371 on 2021-10-15 09:45

hi
i need a very simple client for my embedded project. i have found Paho which relies on mbed and RTOS which is way to complicated for my project. all i need is for the client to send some data to a broker every x seconds. i have found this library:
need a simple MQTT client for stm32f446 with no OS
https://github.com/leech001/SIM800MQTT/tree/MQTTCheckQuestion
which is very good but im not getting any results. i use hivemq public broker to see if my messages are published there. But 99% of the time i don’t see my own messege.and when it does get published,it does so once or twice and not anymore(it is in an endless loop) so i need another library.can you suggest anything? im really lost :-D

thanks for your response! however there is something that i do not understand.For example for IwIP, it has functions such as mqtt_subscribe. Nucleo f446re does not have an inbuilt GSM module right? so im using an external sim800l. how does mqtt_subscribe know which interface to use to send packets? it doesen’t know the AT commands also. so how come people on the ST forums say that it is not dependent on the hardware and that i can use any mqtt client?
