Hi

I want to use SIMCOM7100E GSM module with STM32 board with MQTT protocol stack embedded on it.

Is there any STM32 development board or any STM Development board which supports MQTT protocol stack with simcom7100E GSM module?

♯

?

    Always good to search for existing material:

    https://community.st.com/search.jspa?q=mqtt

    eg,

    Like other internet protocols, MQTT is entirely independent of the underlying hardware.

    So just try googling something like, 'MQTT microcontroller client'

    Note that ST have recently announced some Cellular Discovery Kits:

    Although they may not actually be available yet, check the product pages to see if there's any useful info or software...

    I  had a similar problem last year and find no implementation. So I write my old TCP handler and mqtt client based on lwip's mqtt.The most important thing is the TCP interface with SIM7100 (through AT). The MQTT is not so difficult to implement.

    (Because of company security, i cannot share the source).
