CC3100BOOST: Getting started with WLAN station example failing - connection policies?

Hello,

I am trying to get the example code for the CC3100 - getting started with WLAN station running and can't figure out what's wrong with the code. I was under the impression that this normally should work out of the box. I am working with this attached to a Tiva C TM4C123GH6PM.

I tracked down the issue to the following function:

retVal = sl_WlanPolicySet(SL_POLICY_CONNECTION, SL_CONNECTION_POLICY(1, 0, 0, 0, 1), NULL, 0);
ASSERT_ON_ERROR(retVal);

The retVal returned from this function in main.c is -7, which causes the device to error and loop forever. What would cause this function to return  -7? The weird thing is when I first ran the example it worked (albeit with other errors I can't find due to this not working).

Thank you in advance for any help.
