I had deployed an iot edge on raspberry pi and deploy an MQTT server . So, raspberry pi is acting now as an iot edge and MQTT broker for multiple loaf devices . I want to receive this data from edge device on iot hub OS : linux debian

Hello @AhmedAssad-8581, So you are already familiar with sending messages from IoT Edge modules to the IoT Hub using the $upstream route. Do you want to receive the messages from multiple devices that expose MQTT? You could try one of the available modules in the Marketplace or build a custom module. You could for example build a C# module using this MQTT Client Nuget library. You could even write your own broker, inside a custom IoT Edge module, using this Nuget package.

Thanks for responding , i am not sending messages from iot edge modules . Both of the MQTT broker and iot edge are run individually on raspberry pi and exchange data bet raspberry pi and loaf device using MQTT protocol . So i try to link iot edge with MQTT broker or something that route data from broker to iot hub

Hello @AhmedAssad-8581 ,

You need some Azure IoT Edge logic, a module, which acts as a bridge between MQTT messages and the Azure IoT Edge internal routing.

Does this mean you need a module that can act as an MQTT client and retrieve messages?

In that case, build a module with an MQTT client in the language you prefer or check out the market place.

Building a custom module is not simple when you are just starting with Azure IoT Edge. Check out this documentation first. Some example modules can be found here.

excatly , i want a module that acting as MQTT subscriber or module that get data from broker in order to forward it to cloud
note : when i deploy azure iot edge on raspberry pi and test the MQTT , i see some increasing in numbers in iot hub usage

iot hub sense variation on edge device but i do not know what s logs

Yes, is as expected.

The IoT Edge has a live connection to the IoT Hub.

It waits for deployment manifest changes and is able to react to module twin changes and direct method calls.

When communication is needed, both D2C and C2D, this will be part of that 400.000 messages.

See the documentation regarding the charges per operation.

Note: this is only communication between edge and iothub. Other activities on the device are not part of this.

Okey , in order to show data that sense it , i make a routing for data to blob storage .
and iot hub after this changes ... i do not see any data on storage !!!

Do you see incoming data using the IoT Explorer for your device on the IoT hub?

I suppose you used the IoT Hub internal routing to a blob endpoint.

It can take a few minutes before you see the actual arrival of messages.

Actually , i tried Microsoft azure storage explorer and waiting for some time and not see any data
