We have multiple demos using mqttc connecting with TLS support.
Kindly refer to Onboard_demo / QCLI_demo for more information.

More information is available in sections " Onboard demo with cloud mode" and "6.3.16 AWS Demo"  of document "QCA402x (CDB2x) Development Kit User Guide".

Also, you can refer to below source files.
[target]\quartz\demo\Onboard_demo\src\ecosystem\aws\aws_run.c 
[target]\quartz\demo\QCLI_demo\src\ecosystem\aws\shadow_sample\shadow_sample.c

Hi,
 
First at all, thanks for your prompt reply. 
 
I am trying to study on AWS demo, it seems using aws-iot-device-sdk to do the mqtt with TLS support. 
 
Can I use it to communicate with the other MQTT broker as well ? Or how do I use MQTT Client service of QAPI  to acheive mqtt with TLS support?
 
BR,

Yes, We can use the same connections parametes to establish connection with MQTT broker.

However, the example demo uses sample shadow communication, if you want to update MQTT broker refer to subscribe_sample_publish demo in aws_iot_Device_sdk as we need to call appropriate aws_iot_mqtt_xx() calls.
