Hello,

I have successfully integrated the wifi module with my controller( STM32F429IGT6) but now I a facing a problem in sending and receiving the data to Cloudmqtt through ESP8266. Here I have attached the code which I am using for your reference

When I tried to publish a data to Cloudmqtt using CIPSEND command it is showing NO TAIL, Error

Can you help me with this.?
