casio: pairs-only adapter for the 2C/2D all-features watches - #335
Merged
Conversation
banks version/app/name/module-id/features replies raw over the shared gatt service, nothing decoded. gbx100, gw-b5600, gmw-b5000, ecb-s100 and current models.
Reviewer's GuideIntroduces an explicitly experimental, pairs-only Casio adapter for the shared 2C/2D all-features GATT profile. It performs a fixed sequence of harmless read probes, collects matching notifications as raw data, exposes no physiological signals or settings controls, and integrates the device into BLE discovery, pairing, and profile UI with replay-based tests covering the session contract.

📝 WalkthroughWalkthroughAdds an experimental Casio G-Shock BLE adapter and one-shot synchronization flow. The adapter probes read-only feature tags, buffers notification replies, stores raw frames, and reports module-id length. The registry, background sync, pairing UI, and localized errors now support Casio devices with no declared signals. ChangesCasio BLE support

Hey - I've found 3 issues
Prompt for AI Agents
Please address the comments from this code review:
## Individual Comments
### Comment 1
<location path="lib/ble/adapters/casio.dart" line_range="108" />
<code_context>
+}
+
+/// The single instance. Const, so it costs nothing to reference.
+const CasioAdapter kCasioAdapter = CasioAdapter();
+
+/// Frames off the notify characteristic, buffered so a reply landing before
</code_context>
<issue_to_address>
**issue (broader_impact):** Casio devices can be paired and saved, but no production code drives `kCasioAdapter` or starts a Casio session for the saved `adapter_id`. After pairing, the watch therefore never receives the probe writes and no replies are banked.
**Triggers:** After a Casio watch is paired and the app performs its normal device sync.
**Suggested fix:** Add a Casio link/sync path that dispatches saved `adapter_id == 'casio'` devices to `kCasioAdapter`, or keep Casio out of the pairable UI until that path exists.
</issue_to_address>
### Comment 2
<location path="lib/ble/adapters/casio.dart" line_range="85-92" />
<code_context>
+ 'casio: request 0x${tag.toRadixString(16)} refused; skipping.');
+ continue;
+ }
+ final resp = await inbox.next(replyTimeout);
+ if (resp == null) {
+ link.log(
+ 'casio: no reply to request 0x${tag.toRadixString(16)}.');
+ continue;
+ }
+ raw.add(resp);
+ if (tag == _kModuleIdTag && resp.length > 1) {
+ yield BandNote('casio_module_id_len', resp.length - 1);
+ }
</code_context>
<issue_to_address>
**issue (bug_risk):** The adapter consumes the next notification without checking that its first byte matches the requested feature tag. An unsolicited setting notification, a stale late reply after a timeout, or a reply for another tag is recorded as the current request's response and can produce incorrect raw attribution and an incorrect `casio_module_id_len` note.
**Triggers:** When the watch emits an unsolicited notification or a previous request replies after its timeout.
**Suggested fix:** Have the inbox wait for and return a frame whose first byte matches the current tag, while retaining unrelated frames only if they can be safely matched later.
</issue_to_address>
### Comment 3
<location path="lib/ble/adapters/casio.dart" line_range="102" />
<code_context>
+ // No samples, ever — nothing is decoded. The frames are handed over so a
+ // future decoder, written when someone owns one of these watches, has
+ // something to run over.
+ if (raw.isNotEmpty) yield SampleBatch(const [], raw: raw);
+ // No OffloadCheckpoint: there is no stored history on this wire to trim.
+ }
</code_context>
<issue_to_address>
**issue (broader_impact):** The adapter emits raw frames, but the only existing host persistence hook archives raw bytes through a caller-supplied archive builder; no Casio runtime host supplies such a builder. Consequently, even if the adapter is invoked, the claimed raw banking does not result in `raw_archive` rows and the replies are discarded after the session.
**Triggers:** When Casio is eventually run through the generic `BandHost` without a Casio-specific archive builder.
**Suggested fix:** Wire Casio through a host configured with a Casio raw-archive builder and an appropriate per-frame reason, alongside the adapter dispatch.
</issue_to_address>Sourcery assessment
Needs a human reviewer. 3 findings to address first, and the adapter sends unverified feature-request bytes to real watches and stores each reply as raw session data, so an incorrect wire assumption could cause unintended device behavior or leave incorrect metadata behind after reverting. The impact is bounded and the stored data can be cleared or recomputed; it does not move money, change access, or delete records.
Blocking findings: lib/ble/adapters/casio.dart:108, lib/ble/adapters/casio.dart:92, lib/ble/adapters/casio.dart:102

until the reply deadline expires otherwise. Preserve unmatched frames for their
matching request or store them as unsolicited notifications, and ensure the
module-ID length is derived only from the matched response.

957-958 to use the same localized key instead of a separate literal. Keep both
pairing surfaces on the shared localized description.

…se blurb adds casio_link.dart and dispatches sync from the device row + background sync, matching every other notify-class band. the probe now waits for a reply whose first byte echoes the tag it asked for instead of taking whatever notification arrives next, so a stray or late frame can't get misattributed. the picker's casio category blurb was a bespoke literal skipping localization; it now falls through to the same generic sensor blurb every other notify-class band uses.

- Line 83: Move discoverServices() and all subsequent post-connect setup into
the try/finally scope inside withSecondaryLinkSlot, ensuring every success or
failure path reaches one finally block that calls both stop() and
device.disconnect().
In `@lib/ui2/profile/devices.dart`:
- Around line 1531-1532: Update CasioLink._sync and _syncCasio so expiration of
_listenWindow produces a distinct failure or timeout result instead of returning
true; map that result to the failure message rather than devicesSynced, while
preserving the success mapping only for probes that complete successfully.
- Around line 1533-1534: Update _syncCasio to use the localized
devicesCouldNotReachWatch string when CasioLink.instance.sync() returns false,
while preserving the existing fallback behavior. Add the
devicesCouldNotReachWatch translation entry to every ARB localization file.
- Line 1491: Update the manual-sync callback invoking _syncCasio so it passes
the selected device ID, then propagate that ID through _syncCasio to
CasioLink.sync and make CasioLink.pairedRow select the exact matching Casio row
instead of defaulting to the first row.

…imeout buildArchive was never wired to BandHost, so every probe reply the adapter banked was silently dropped instead of reaching raw_archive. Wired it, one reason per tag, same shape as oura/zetime. discoverServices() (and everything before the host was built) sat outside the disconnect finally, so a throw there leaked the BLE connection. The whole connect-through-probe span is now one try/finally. CasioLink.pairedRow() always returned the first Casio row; with two watches paired, syncing the second row's card synced the first watch instead. sync() now takes the row's own deviceId and the UI passes it. A probe that timed out on the listen-window backstop still returned true. It now reports failure, with a real reason string instead of the literal English fallback, plus its five translations.

Covers the primary-device-id guard, pairedRow's multi-device selector, sync()-no-op with nothing paired, and _buildArchiveRow's construction — none of it had coverage; a regression in any of these paths would have shipped with all existing tests green.
