Receive commands only once, and only one about iot-hub-c-m0wifi-getstartedkit

As I recall the example remote monitoring example only does one sample and likewise one command. You will need to create a loop. The work of sending the serialized sample and of processing the incoming command are both done within IoTHubClient_LL_DoWork().

@GregTerrell thanks for responding. I figured out what my issue was: I was using HTTP protocol to send/receive messages, and the SDK only checks for commands every 25 minutes or so, as per current HTTP guidelines. So, even though my while loop was calling dowork, there was no work to be done because the client hadn't polled the IoT Hub yet. Unfortunately, MQTT is not currently working on the Arduino Feather M0, though. Thanks!
