IoT Edge transparent gateways support only the MQTT or AMQP protocols. Instead use a translation gateway. IoT Hub. The translation module receives messages from downstream devices, translates them into a supported protocol, and then the IoT Edge device sends the messages on behalf of the downstream devices. All information looks like it is coming from one device, the gateway. Reference: https://docs.microsoft.com/en-us/azure/iot-edge/iot-edge-as-gateway
