Chirp says it is on a mission to simplify connectivity using sound. Chirp’s machine-to-machine communications software enables any device with a loudspeaker or microphone to exchange data via inaudible sound waves.
Thanks to some compatible libraries included in the official Arduino Library Manager and in the Arduino Create — as well as further comprehensive documentation, tutorials and technical support — it will be easy for anyone to add data-over-sound capabilities to their Arduino projects.
Our new Nano 33 BLE Sense board, with a DSP-optimised Arm Cortex-M4 processor, will be the first board in the Arduino range with the power to transmit and receive Chirp audio signals leveraging the board’s microphone as a receiver. From now on, the Chirp SDK for Arduino will support the following boards in send-only mode: Arduino MKR Zero, Arduino MKR Vidor 4000, Arduino MKR Fox 1200, Arduino MKR WAN 1300, Arduino MKR WiFi 1010, Arduino MKR GSM 1400, Arduino MKR NB 1500 and the Arduino Nano 33 IoT.
Creative applications of Arduino and Chirp include
- Triggering events from YouTube audio
- Securely unlocking a smart lock with sound
- Sending Wi-Fi credentials to bring offline devices onto a Wi-Fi network
