Hello [@haricane00](https://maker.wiznet.io/u/haricane00)

To connect MQTT with SSL/TLS, set to ‘1’ in ‘AT+MQTTCON=<enable>,<broker IP>,<broker port>’.

However, it does not support entering certificates used when connecting to MQTT using ‘AT+MQTTCON’.

If you want to enter certificates, you can implement that part on the application and use it.

This is an example of implementing and using certificate-related applications.

Please refer to the example above.
