Cloudmqtt connection using GSM and STM32


#1

Hello Sir,
I am trying to connect cloudmqtt using GSM and STM32 module. I had watched your video Arduino MQTT Tutorial - Coding Live Demo using SIM900 and convert the same code for STM32. I am getting response SEND OK for At+CIPSEND. But data is not visible in cloudmqtt. can you please help me solve this problem.?

You should post what is the module response for each command and see if you are getting MQTT acknowledgement packets for Connect packet and publish packet. These are normally 2 byte binary values. Use tools like TMFT or Docklight to see these.
