Hi Sankar,
You should look at the UART command capture to see whats happening.
Are you able to send the data ?
When is this disconnection occurring. ?
Normally when we send a malformed packet , the broker disconnects the client.
So make sure your packets are formed correctly.
The protocol name for cloudmqtt broker is MQIsdp. Check these and let me know.
If you can observe the command flow on UART it will be helpful in debugging.
