LoadProhibitedCause when trying to send message to IoT Hub #100

I'm trying to deploy this example onto my WS8266: https://github.com/Azure-Samples/iot-hub-SparkFun-ThingDev-client-app.git

It compiles just fine, but when I run it I get the following output

connected with (NO SSID), channel 6
dhcp client start...

Then the board reboots and starts over again. Is there something I didn't configure properly?

Very likely. Please follow these setup instructions for ESP8266 boards: https://github.com/Azure/azure-iot-pal-arduino/blob/master/build_all/base-libraries/AzureIoTHub/README.md#esp8266

Let me know if following those steps helped. If no response within a week, I will consider this resolved.
