README

bt-hci

Rust types for the Bluetooth HCI (Host Controller Interface) specification, and traits for implementing the Controller part of the interface.

See Trouble for an example of using this crate.

Bluetooth UUIDs

The bluetooth specification includes reference information for pre-defined UUIDs that can be used to communicate specific services, characteristics, properties, etc of a device. These are also made available as constants from this crate through the uuid module for users of this crate.

For crate maintainers, to update these constants run the update_uuids binary, which will redownload the bluetooth-sig yaml spec and rebuild the uuids module based on the latest version.
