This device bridge only forwards messages to IoT Central, and does not send messages back to devices. Due to the unidirectional nature of this solution, `settings` and `commands` will **not** work for devices that connect to IoT Central through this device bridge. To use these features, a device must be connected directly to IoT Central using one of the [Azure IoT device SDKs](https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-sdks).

Due to the unidirectional nature of this solution, `settings` and `commands` will **not** work for devices that connect to IoT Central through this device bridge. Because device twin operations are also not supported, it's **not** possible to update `device properties` through this setup.

i tried to connect a Sigfox sensor from the sigfox cloud to IoT central through this device bridge. I do receive "messages" sent from the sigfox cloud in my function but there is an error which prevents me from sending the actual data to IoT Central : "the DeviceId must be alphanumeric, in lower case and may content hyphens". But I do not understand why this error is generated knowing that my deviceID follows all the rules.
Hoping that someone could help me.
Thanks.
If so, it's picking up the device Id directly from the payload sent by Sigfox. To see what the transformed payload look like and make sure the device Id is in the correct format, you can add a call to context.log(JSON.stringify(req.body)); right before the call to handleMessage in index.js of the Azure Function. (do not paste the output here as it may contain sensitive data)

@elies92, have you already applied the steps in the README specific for SigFox devices? (https://github.com/Azure/iotc-device-bridge#example-2-connecting-sigfox-devices-through-the-device-bridge)
