CC32XX SLNET use multiple sockets

Hi Benjamin,

The SlNet parameter in SysConfig is actually an instance of a IP network stack. This is especially useful when you are using multiple network stacks (like Wi-Fi and Ethernet). The SlNet library is used by all the Network Services libraries, including MQTT and OTA. You can find more details about the NS libraries in the NS user's guide.

The MQTT and OTA libraries manage their own sockets, so your application does not need to create separate ones. If you open the mqtt_client or cloud_ota examples, you can see they only have one CC32xx instance of the SlNet library configured. I suggest working from the mqtt_client example over the mqtt_client_server example, since the mqtt_if abstraction layer in the mqtt_client example is a lot simpler than using the MQTT library directly.

If you do want to create new sockets, this is done in the application code. See the examples in the examples/rtos/<LaunchPad>/ns folder.

Best regards,

Sarah
