How do I send data from Data Loggers to Azure IoT Hub or AWS IoT?

Question

I want to send my data to either MS Azure or AWS IoT platform through my Data Logger. How do I do it?

Answer 1

Azure IoT Hub exposes device endpoints:

Device endpoints

For each device provisioned in the device identity registry, IoT Hub exposes a set of endpoints that a device can use to send and receive messages:

• Send device-to-cloud messages. Use this endpoint to send device-to-cloud messages.
• Receive cloud-to-device messages. A device uses this endpoint to receive targeted cloud-to-device messages.

[...]

These endpoints are exposed using MQTT v3.1.1, HTTP 1.1, and AMQP 1.0 protocols. Note that AMQP is also available over WebSockets on port 443.

The simplest way would be a REST call:

POST https://{IoTHubName}.azure-devices.net/devices/{deviceId}/messages/events?api-version={api-version}

The body can be any octet-stream. Note that the size of the whole message (body plus properties) has to be less than 256 Kb.

e.g.

$ curl -X POST https://heresthething.azure-devices.net/devices/aNewArduino/messages/events?api-version=2016-02-03 \
       -H "Authorization: SharedAccessSignature sr=HeresTheThing.azure-devices.net&sig=t8Pf2lXXXVDlMY%3d&se=1489585285&skn=device" \
       -H "Transfer-Encoding: Chunked" \
       -H "Connection: Close" \
       -k -v \
       --data "New Arduino, who dis?"

Use Device Explorer to register your device(s) and generate SAS.

You should start here:

Depening on the scale of your project (2 devices or 2000?), you may want something less complex, like App Service Mobile Apps with Easy Tables. It's essentially a CRUD API.

A POST is all you need to ingest telemetry. You can then use OData v3 syntax to GET and filter your data set.
