I recently got a web cam device and when I read the instructions to “place the phone near the camera so that it can listen to the camera” I thought I was dealing with an epic example of mistranslated text.

However, shortly after hearing a series of chirps and beeps reminiscent of R2-D2, the camera was configured.

Well, it turns out that there’s an SDK for that and it works with Azure.

Chirp (https://chirp.io) created enterprise-ready, cross platform SDKs for transmitting data over sound and the Azure IoT team collaborated with Chirp to implement a nice and easy way to setup an MXChip devkit and connect it to Azure IoT Central using just sound.
