- btintel.rs: run_intel_command() sends a command and waits for the
matching command-complete (opcode + status check). intel_read_version()
parses the Intel version response. intel_download_firmware() streams
the full SFI command sequence (CSS header + PKey + signature + payload
fragments), rejecting on controller NACK. intel_setup_firmware()
orchestrates bootloader detection -> enter MFG -> download -> exit MFG
-> DDC apply -> version re-read. apply_ddc_config() replays the DDC
command records. read_firmware_blob() probes scheme and /lib/firmware
(flat + intel/ layouts).
- main.rs: wire intel_setup_firmware into daemon_main for Intel CNVi
adapters (vendor 0x8087) before standard HCI init; no-op on
operational controllers, non-fatal on failure.
- 4 new tests (download ACK/NACK, opcode match/mismatch); 164 total pass.
Ported from Linux drivers/bluetooth/btintel.c.
Also: btusb firmware download command sequence + plan doc updates.
- btintel.rs extended: firmware_download_commands() generates the
full HCI command sequence for SFI firmware download (CSS header +
PKey + Signature + payload fragments). RSA and ECDSA header types
supported. secure_send_commands() splits data into 252-byte
fragments with type prefix. extract_boot_param() finds the
CMD_WRITE_BOOT_PARAMS record in firmware data. 5 new unit tests
(160 total pass).
- acpid/scheme.rs: ThermalZone handle kind for per-zone ACPI thermal
data. /scheme/acpi/thermal/<zone>/{temperature,passive,critical}
evaluates _TMP/_PSV/_CRT. thermald can now read real thresholds.
- Plan doc: Phase 7.1 updated with download command sequence.
ACPICA assessment updated with thermal zone methods.
Add ATT/GATT protocol types to btusb hci.rs: AttPdu with 8 builder
methods, GattService/GattCharacteristic discovery types, ATT response
parsers, ATT-over-ACL L2CAP helpers. 12 new tests (137 total btusb).
Migrate i2c-hidd from legacy ProducerHandle to InputProducer with
named producer fallback (i2c-hid), completing U3 driver migrations.
Update BLUETOOTH-IMPLEMENTATION-PLAN.md with B1/B2 completion evidence,
exit criteria assessment, and updated support language.
Add complete HCI protocol module (hci.rs) with packet types, 55+ constants,
command builders (Reset, Read BD Addr, Read Local Version, LE scan/connect),
event parsers, and structured result types. Add USB transport abstraction
(usb_transport.rs) with UsbHciTransport trait and StubTransport for testing.
Wire btusb daemon with endpoint descriptor parsing, HCI init sequence
(Reset → Read BD Addr → Read Local Version), ControllerState state machine,
and enhanced status output. Replace all expect()/unwrap() calls in btctl
and wifictl with proper error handling and graceful fallback.
91 btusb tests, 27 btctl tests, 2 wifictl tests passing.
