One of the major reasons for utilizing an Azure Iot Edge Gateway is to connect devices to the internet that can’t directly establish a connection themselves. A very common case are Bluetooth beacons, that can provide sensor data through a Bluetooth Low Energy (BLE) connection but are not able to send this information directly to an Azure IoT Hub.
For this scenario a bridge or gateway is required to create an IoT message from the Bluetooth payload. This is called Protocol Translation and can be achieved by creating a custom IoT Edge Module. Interestingly enough Microsoft has still not managed to provide a sample or best practice on how to do this with the IoT Edge Runtime V2, so here’s how we did it in our latest IoT project.Bluetooth Low Energy BLE devices with Azure IoT Edge weiterlesen
