Testing if messages from my Device is reaching the Azure IoT Hub

Question

I have two event generators connected to the Azure IoT Hub. Now, if I publish a message from my Raspberry Pi to either the Azure IoT Hub or my other connected device, how do I know if my message was received and what message exactly arrived?

Answer 1

Download the Device Explorer open source tool and configure your connection string with it to monitor their messages. Go to "Message to Device" to select your device in the Device ID Tab and click the "Monitor Feedback Endpoint" checkbox for checking if your device is reachable by the IoT Hub. You'll always be shown the status of messages whenever a message is published in the callback/feedback message. And, the messages get deleted only after the specified retention period for the Hub.

And, if you want to check via the outputs of code, check the DeviceExplorer source code https://github.com/Azure/azure-iot-sdks/tree/master/tools/DeviceExplorer/DeviceExplorer and, also the monitor code MainForm.cs, from line 726.

Hope it helps!
