MKR 1010 Getting a -2 Return Code about mkr1000-iotc HOT 3 CLOSED

The code was designed to work against Azure IoT Central (https://azure.microsoft.com/en-us/services/iot-central/). The ScopeID is specific to IoT Central as we use the Device Provisioning Service to get the IoT Hub to connect to. To make this work with a regular Azure IoT Hub you will need to change the code so it works like a MKR1000 (due to technical issues we cannot get this device to work with DPS yet so it drops back to a connection string). Look at the code in mkr10x0_iotc.ino and change line 25 to be mkr_devices mkrdevice = MKR1000; Then paste in the device connection string into line 5 of configure.h and you should be good to go!

Hey FD: Thanks. That worked. I get:

Sending telemetry ...
{"temp": 62.12, "humidity": 67.22}
--> IoT Hub acknowledges successful receipt of twin property: 2

I am going to try to understand your code a little better and pull out some of the Central code. I am preparing for the MKR 1500 when it starts to ship.

Thanks again.

Excellent, glad I could help you out. Yes you can pull out the code specific to IoT Central and reduce the firmware size. We're also excited for the MKR1500 as it opens up low power communication to Azure IoT. If you run into any other problems feel free to ping me and I'll try and help out. For now I'm going to close this issue.
