Does Azure IOT hub behaves the same as Mosquitto Broker. Can't we have Device to Device communication with just topics like in Mosquitto Broker, Is it neccesary to write a function app / any routing mechanism to route messages from one device to device

    Thanks @Sander van de Velde | MVP . Below page

    https://learn.microsoft.com/en-us/azure/iot-hub/iot-hub-mqtt-support#receiving-cloud-to-device-messages mentions

    The device does not receive any messages from IoT Hub until it has successfully subscribed to its device-specific endpoint, represented by the devices/{device_id}/messages/devicebound/# topic filter. After a subscription has been established, the device receives cloud-to-device messages that were sent to it after the time of the subscription.

    it means the device receive from a logic app which is sending messages to device. i mean if any Logic app with Cloud to Device persits, then only devices can receive it

    Hello @praveen ,

    The Azure IoT Edge recently started to include a MQTT broker.

    have you seen this article already?

    Thanks @Sander van de Velde | MVP . My question is " Is Azure IOT HUB" not same as mosquito broker. In mosquito broker a device automatically receives to topics it subscribed. Will it happen same in Azure IOT HUB.
    OR
    A function app/ routing is needed to route messages from one Device to another Device ??
    Can't subscribed devices receive automatically to their subscribed topics ??
