fossil/skagen q hybrid: pair and bank raw bytes, pairs-only - #337
Merged
Conversation
original hybrid line (misfit-derived, HW/HL/DN models), not the newer hybrid HR. plain unencrypted gatt, no auth. self-confirms with a battery probe on connect since the encrypted HR sibling shares the same service uuid. banks every notification raw, decodes nothing, declares no signals.
both tests intentionally pin the exact set of registered adapter ids; add qhybrid to the list they now must extend.
Reviewer's GuideIntroduces an experimental Fossil/Skagen Q Hybrid BLE adapter that distinguishes the plain protocol from its encrypted sibling with a battery-level probe, then pairs and banks notifications as raw arrival-timestamped bytes only; registry, UI, and focused tests are updated accordingly.

Hey - I've reviewed your changes and they look great!
Sourcery assessment
Needs a human reviewer. If the probe or protocol assumptions are wrong, the adapter can persist raw notifications from the wrong device or include pre-confirmation bytes once a later probe succeeds. Reverting stops future collection, but already banked raw records remain and would need bounded cleanup.

In `@lib/ble/adapters/qhybrid.dart`:
- Line 72: Update the SampleBatch creation in the characteristic-processing flow
to attach the originating characteristic identifier as raw-record metadata for
every frame. Propagate this metadata through raw persistence and replay while
leaving the received payload bytes unchanged, so packets from symbols such as
kQHybridFileChar1, kQHybridAuxChar, and kQHybridUploadAckChar remain
distinguishable.
- Line 72: Update the notification handling around the probe confirmation state
so non-probe notifications received before a valid battery reply are discarded
rather than added to raw. Set the confirmation flag immediately when the valid
probe response arrives, and only enqueue SampleBatch values after that flag is
true.

pairing only wrote the device row and ran one bounded drain window that never repeated. QHybridLink now holds that session as sync()/forget(), matching the shape DafitLink already uses for a band with no history and no signals: connect by remote_id, run the adapter for a bounded window, bank whatever comes back. wired from the profile devices screen (manual sync tap), the periodic background pass alongside oura and dafit, and HrsLink.forgetDevice's per-adapter dispatch. pairQHybrid now drives the same sync() path instead of a separate duplicate drain.

pairQHybrid went through HrsLink.pairNotifySensor with no tier override, so the default 'beatToBeat' landed on a device that decodes nothing. pairNotifySensor's tier param is now nullable so a zero-signal adapter can refuse a tier the same way pairOuraRing already does.

Inline comments:
In `@lib/ble/qhybrid_link.dart`:
- Line 193: Update the cleanup flow around BandHost.stop() so host-field cleanup
and watch disconnection execute in a finally block even when stop() throws
during raw-frame flushing. Preserve _sync’s error propagation while ensuring the
live GATT connection is always disconnected after releasing the secondary-link
slot.
- Line 174: Update QHybridAdapter.run and the surrounding BandHost flow so a
refused write or missing probe reply is propagated as an unsuccessful result
instead of completing normally and reaching the return true path. Ensure the
encrypted sibling protocol is reported as false unless probe confirmation
occurs, either by carrying confirmation out of QHybridAdapter.run or probing
before BandHost starts.
- Line 143: Update the sync flow around withSecondaryLinkSlot and
BluetoothDevice.fromId so queued work is invalidated when forget() calls stop()
and deletes the device row. Add a session-generation check after slot
acquisition and before every publish path, or otherwise defer row deletion until
the in-flight sync completes, ensuring stale sync closures cannot connect with
the captured remoteId or archive frames under the deleted deviceId.
In `@lib/ui2/profile/devices.dart`:
- Line 1532: Update _syncQHybrid to replace the hardcoded connection, success,
and failure SnackBar messages with localized values from AppLocalizations.of(c),
and add the corresponding localization keys while preserving the existing
feedback flow.
- Line 1533: Update the handler around QHybridLink.instance.sync() to preserve
and distinguish the sync outcome before selecting the SnackBar. Separate busy,
connection/setup failure, probe rejection or adapter abstention, and confirmed
success instead of mapping every false result to “Could not reach…” or treating
host.run(link) completion as success; adjust _sync() and its caller to return an
explicit outcome as needed.
- Line 967: Update the pairing and synchronization configuration around
pairQHybrid so Q Hybrid is only exposed when encrypted transport is explicitly
enabled; otherwise exclude this adapter from normal pairing and synchronization
rather than allowing raw qhybrid_raw notifications.
- Line 967: Update the device-selection flow using pairQHybrid so the
asynchronous protocol probe is not treated as authentication: require a
cryptographically authenticated device identity and pairing key before
persisting remote_id and accepting frames, or explicitly restrict and enforce
operation to trusted local devices.

…on flush failure sync() now reports the actual probe confirmation instead of `host.run` completing regardless — the adapter passes it out on the existing BandNote channel. forget() racing a still-queued sync no longer lets that sync connect and archive frames under an id its own row deletion just removed. stop() disconnects in a finally so a raw-archive flush error doesn't leave the watch connected with nothing driving it. also localizes the watch sync snackbar, same as the ring's.

User description
plain unencrypted GATT, no crypto handshake, no pairing key — same "pairs and banks raw bytes only" shape as the generic BLE HR strap. the same service UUID is also worn by the encrypted Hybrid HR / Gen 6 line, so before banking anything the adapter writes a harmless battery-level query and waits for a matching reply — no reply means it's the other protocol and it abstains.
experimental, decodes nothing: empty signals map, not in kDerivableSources. nobody here owns one.
