Remote monitoring example compile error.

[santaimpersonator]

So, I'm not sure why I can't get the sample code to compile or what the verbose output means.

I'm following the tutorial here for the first example Running a Simple Remote Monitoring Solution with the SparkFun ESP8266 Thing Dev Kit (Arduino-compatible): https://azure.microsoft.com/en-us/resources/samples/iot-hub-c-thingdev-getstartedkit/ I get stuck in section 1.8 where the code compiles: https://azure.microsoft.com/en-us/resources/samples/iot-hub-c-thingdev-getstartedkit/#section1.8

@santaimpersonator : The missing 'strtof' is an indication that your version of the ESP8266 library is out of date. The "ESP8266 by ESP8266 community" library needs to be at least v 2.4.0
