How to connect Azure IoT Edge to IoT Central

Егор Карташов 6

The solution architecture includes the following:
There is a device A (IoT Edge) where has SQL DB. Data must be send to B (IoT Central), but it's not slightly easy. I know how to transfer data from device A directly to C (IoT Hub), but perhaps it is possible to send telemetry data directly to B, or it's need to first transfer data to C and then to B, right?
In first case I should use connection through modules (SQL Edge), but in another case what we need?

I guess, has some possibilities send data from OPC UA Publisher pipeline (not to $upstream first) to Stream Analitics input on Edge device and then put it to SQL Edge DB input. After then send it with helps another SA to IoT Central (or maybe IoT Hub?)...

I probably have more questions than answers at this point, but here are some thoughts/questions:
Have you tried connecting your edge devices to IoT Central? IoT Central supports IoT Edge just like Hub, so you don't have to trick your modules into sending your telemetry somewhere else.
If you have a module on your device that's sending data to hub, you can use module routing to route that same data into any other module. This could be Azure SQL Edge, a Streaming Analytics module, a Function module, or any module of your own making. You can also route one module output to multiple inputs, so there are a lot of combinations to make.

Thanks for you reply, MatthijsvdVeer! So, redirect data from OPC Publisher directly to SQL on Edge (Azure SQL module) and then process some data with helps Stream Analitics also in Edge device and send it to IoT Central, does it work? If you can, please, leave a couple of useful links on this topic.

Azure SQL edge has many capabilities, you can stream messages to it, but you can also connect to it as you would to other SQL databases. It's definitely worth the trouble going through all the documentation. Depending on your situation, you might not need Stream Analytics if the Azure SQL module covers your use case. And yes, eventually sending the message to IoT Central definitely works.
