 Upon completion of this guide, you will be able to add the MQTT/TLS module to your own design, configure it correctly for the target application, and write code using the included application example code as a reference and efficient starting point. References to more detailed API descriptions, and other application projects that demonstrate more advanced uses of the module, are in the Synergy Software Package (SSP) User’s Manual, and serve as valuable resources in creating more complex designs.
