Good day!
In Flowcode, MQTT (MQTTClient and IoTMadeEasy) is implemented via NetworkComms to WLAN or Ethernet, but not via UART (RS232).
Is it possible to implement MQTT via UART?
I'd like to transmit MQTT data via UART to the SIM800.

Re: MQTT UART
Hi
Yes, very much so. I am traveling just now so need to be brief, but take a look at these posts

It may give you a start. It is for 76xx modules though. The 800 is 2G and is being retired in many countries (if not already).
Connect your uart tx/Rx to module (careful of level shifting).
The old forum has more posts regarding this.
Regards
