title: How to implement MQTT on Zephyr OS with cellular devices?
body: <p>I am a beginner on Zephyr OS and wanted to know if it is possible to implement MQTT on Zephyr OS with Cellular Devices like SIM800 or Quectel BG96 that usually work on UART and support TCP protocol which is the base of MQTT.</p>
  
  <p>I looked through the example for MQTT given for Zephyr which is done over LAN but could not figure out how to implement the same with a cellular device.</p>
