How To for Android/iOS MQTT clients

[j-floroiu]

Hi,

Is there more detailed information available on how to use https://learn.microsoft.com/en-us/azure/iot/iot-mqtt-connect-to-iot-hub#using-the-mqtt-protocol-directly-as-a-device and/or https://learn.microsoft.com/en-us/azure/iot/iot-mqtt-connect-to-iot-dps#using-the-mqtt-protocol-directly-as-a-device with available MQTT clients?

For instance, I tried out MQTT Dashboard and MyMQTT apps on an Android, but without success so far.

Thanks.

Hi! Thank you for following up! I was trying out these two MQTT clients on an Android phone. I filled in the credentials as described in the howtos, tried out a few variations, because the attributes there do not match one-to-one the fields required by the apps, but did not manage to establish a connection to the Azure IoT hub/dps. The error messages on the phone just say "failed to connect", don't provide any useful hint, but I am assuming it's because incorrectly formatted URL / credentials. I would appreciate if you could provide a more detailed howto for any generic MQTT client app.

Thank you, John
