Measure the maximum number of notifications per second with different connection parameter settings. Compare with a physical mouse/keyboard.

The current plan is to use Nordic’s nRF Sniffer to record BLE traffic from a hardware keyboard/mouse and compare it with the traffic generated by our software stack. There should be no obvious differences. The exact metrics are TBD, especially if it proves difficult to capture unencrypted traffic from the hardware devices.

Allow using Resolvable Private Addresses for local and remote devices ([Vol 6] Part B, Section 6). This is required for communicating reliably with Android and iOS devices, which generate new random addresses when the Bluetooth stack is restarted.

General

• Split README.md and crate documentation?
• General documentation cleanup.
• Simplify Error types and review the design.
• Review logging structure and maybe switch to span-based logging in places.
• Replace uses of std with core/alloc to start moving toward no_std support.
• Remove unnecessary derives.
• Restrict visibility for internal library components.

USB

• Put usb backend behind a feature flag.
• Do not expose rusb::Error.

HCI

• Populate hci::Conn::local_addr when the connection is created. This requires hci::Host to track advertising state commands.
• Block on hci::Error::CommandQuotaExceeded.
• Store DisconnectionComplete reason.
• Log informational events (e.g. ReadRemoteVersionInformationComplete, LePathLossThreshold).

L2CAP

• Handle L2CAP Signal channel events.
• Get rid of l2cap::Alloc and cache transfers in RawChan.

SMP

• Send encryption request when the client first connects.
• Handle SMP rate limiting and repeated pairing attempts.
• Atomic file storage.
• Review smp::{Display, Confirm} API.

HID

• Review HID module design and simplify for the new API.
• Use physical DPI units for the mouse.

Add libusb hotplug support to handle controller attach/detach events.

We currently require any USB controller to have an active configuration set by the OS. macOS seems to put USB dongles into an unconfigured state, which then breaks endpoint discovery.

Windows 11 doesn't seem to re-discover services after failing to re-establish a bond (e.g. because Peripheral cache was cleared) and negotiating a new LTK. We should detect a failed LTK request and use that to trigger a Service Changed indication even if the GATT cache is gone.

Tracking issue for Central support.

Bluetooth Assigned Numbers are now available from an official public repo in YAML format. Write a build script to auto-generate company ID table and UUID definitions.

Implement full-stack closed-loop testing with a simulated host::Transport. This requires some Central support (#5).
