CC3200: sl_ExtLib_MqttClientConnect() doesn't return when no Internet connectivity

Part Number:CC3200

Hello,

I have the cc3200 in station mode connected to the router. However, the router has no internet access. I call sl_ExtLib_MqttClientConnect() and it doesn't return. I have blocking_send set to false.

In the documentation it reads that it should return -1 on failure. Isn't failure to reach the server such a failure?

Thanks!
