Clearly this is a demo Azure function which simply writes log messages. Just wondering how have others implemented this in real life scenario, for instance do you modify the function to post the messages into an Azure IoT Hub or Event Hub or directly write to a database / storage?
There is also information on connecting to Azure IoT central, from last years conference at https://azure.microsoft.com/nl-nl/blog/the-things-network-and-azure-iot-connect-lorawan-devices/ You will need to modify the code a bit as the new http integration has different message format but that is fairly trivial. (Or ping me if you decide on this solution, I’ll share the few lines of code to you need to modify)
Make sure to investigate what the Azure options offer you. Does it match your requirements? (Historic data, query options for data discovery, what do you need?)
