Device provisioning

Seamless connection

Data-over-sound requires no pairing or configuration, making data transfer as simple as pressing a button.

The most advanced solution for many device-to-device connectivity applications, particularly for use cases that require frictionless, low cost connectivity with nearby devices.

Trillbit provisioning solution is offline, proximity-bounded, and does not require any infrastructure modifications.
Credentials are encoded as ultrasonic audio, optionally layered with encryption for secure scenarios, and broadcast over-the-air to nearby smart devices.
