I'm trying to decode AMQP messages sended and revived between Azure IoT Edge and Azure Hub. At this moment I can read the data inside the socket, having something like this:

enter image description here

Now, I'd like to see this packages as json or object or something that a human could read.

Any help to decode this? Thanks in advance.

  • See: [Understand how Azure IoT Edge uses certificates](https://learn.microsoft.com/en-us/azure/iot-edge/iot-edge-certs?view=iotedge-2020-11). Those certificates enable a TLS (transport layer security) secure connection between the runtime, the modules, and the IoT devices. Can you explain better what you are trying to achieve? – asergaz Feb 11 '22 at 07:55

not sure what you are trying to achieve.

Are you sniffing the traffic between your device and IoT Hub over the wire? This is encrypted as all the comm toward IoT Hub uses TLS.

Do you want to support the AMQP protocol for a device that can't use one of the IoT hub SDKs?

In this case, if you can use an AMQP library, I would suggest to have a look at this document: https://learn.microsoft.com/en-us/azure/iot-hub/iot-hub-amqp-support. That document describes how IoT Hub leverage the AMQP protocol to abstract the IoT Hub messaging patterns (D2C, C2D, Direct Methods and Twin updates).

Nevertheless, if you are writing an iot device agent / firmware, I would probably suggest to start with MQTT as a protocol, way simpler especially if you can't use SKDs.
