R&D Stories: Achieving Frictionless Lower-Power Application Connectivity with Data-Over-Sound

Anytime we need to login to the local Wi-Fi or pair with another Bluetooth device, we think, "There must be a better way to do this!" That's precisely one of the exciting possibilities for data-over-sound technology. This article explains what else we can do with it, and how it works. It also explores how data-over-sound can be realized in embedded scenarios, and how Chirp’s new technology, using the Arm Cortex-M4 and Cortex-M7 processors, can be implemented in connected products.
