Concept Board connection to Azure IoT Cloud with MQTT Protocol
Showcase, April 13, 2018 - 1:54pm, 9739 views
This showcase is a simple example showing how to establish secure connection with IoT Cloud in order to publish/subscribe messages via MQTT protocol.
In this case connection is being established with Azure IoT Cloud via MQTT protocol. To use the MQTT protocol directly, the client must connect over TLS/SSL. Attempts to skip this step fail with connection errors. In this showcase X.509 certificate authentication is used. Mutual authentication is required. It means, that while establishing a connection, client must prove its identity to a server, and the server must prove its identity to the client.
Application data will not be transferred over the client-to-server connection, until mutual authentication succeed.
While accessing Azure IoT Hub, Cinterion Concept Board is a Client, which should prove its identity using a self-signed X.509 Device Certificate.
Both Client's and Server's certificates need to be installed on Gemalto M2M module.
In order to communicate with IoT Cloud using MQTT Protocol, it is necessary to install a MIDlet serving MQTT protocol on the Cinterion Concept Board.
The showcase related to preparing MIDlet based on latest Paho project you may find here: https://iot-developer.thalesgroup.com/showcase/paho-project-110-july-2016-mqtt-311
Please, remember to adjust the MIDlet to fulfill Azure IoT Cloud requirements for MQTT connection. Details you may find there: https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-mqtt-support
