When I add a call to function IoTHubClient_LL_SendReportedState in my sketch, the call and web request succeeds (the server receives the data), but seconds later the sketch freezes during one of the calls to delay(10). The WDT then resets the module after a few seconds (indicated in serial output). I can only assume this is caused by something screwy that the IOT SDK library did, but the freeze does not occur during the library calls; it occurs inside delay(). There is no serial output indicating root cause. How can I find the offending loop inside delay()?
