title: Azure IoT Hub AMQP Communication Multiplexing
body: <p>In some of the <a href="https://azure.microsoft.com/en-us/documentation/articles/iot-hub-devguide/" rel="noreferrer">Microsoft documentation</a> for working with Azure IoT hubs, it mentions that it is possible to multiplex the communication of multiple devices under a single TLS connection (using the AMQP protocol) for scenarios where multiple simple devices talk to a local hub device that is powerful enough to communicate with the IoT Hub. Are there any examples of how one would implement this multiplexing? The <a href="https://www.nuget.org/packages/Microsoft.Azure.Devices.Client/" rel="noreferrer">DeviceClient library</a> does not appear to support this (although I could be wrong). There have also been mentions of the IoT Gateway SDK for this scenario, but I haven't found a clear example of how to set multiplexing up using that either. Any advice or references to other material would be appreciated.</p>
