Introduce BatteryLayout enum with size-driven dispatch. Drops minWidth from 80dp to 40dp so the battery widget can be placed at one cell. At 1-cell-wide placements render a compact icon+percent stack; wider sizes keep the current NARROW/WIDE layouts.
Drops stale app-common/Wear OS references, renames migrated classes
(ReactionSettingsFragment/PopUpPodViewFactory/PodMonitor), documents
the BLE/AAP split in monitor/core, the layered AAP stack, Widget
(Glance) and Upgrade subsystems, Navigation3 + legacy helpers. Fixes
localization examples and screenshot pipeline counts.
New home-screen widget that toggles AirPods ANC modes (Off / ANC / Transparency / Adaptive) directly, with six adaptive layouts that pick based on widget size (QUAD_CORNERS, ROW_ICONS, COLUMN_ICONS, GRID_2X2, ROW, COLUMN). Consolidated battery+ANC configuration into a single ViewModel that detects widget type from AppWidgetManager. ACTIVE state uses Material3 secondaryContainer/onSecondaryContainer for guaranteed contrast. Includes live config preview, preview subtitle, stale-selection guard, device-label toggle, and aligned icons with the app's AncModeSelector.
Adds Stop, Fast Forward, Rewind, Mute, Cycle Noise Control, and Toggle Transparency as gesture targets. Migrates StemAction from enum to sealed interface with polymorphic serialization to unlock future parameterized actions. ANC actions are gated per-device capability and reuse the existing listening-mode cycle mask.
Move press timing, call controls, and stem mappings out of the Controls card into a new Press Controls screen. The screen name is device-agnostic so it applies to both stemmed AirPods and the AirPods Max's Digital Crown/noise button.
Stem mappings are now per-device (stored on the AppleDeviceProfile) rather than a single app-global DataStore. The Pro gate for mappings moves from screen entry to per-change with an Upgrade badge on the mappings card header, so free users can still access the non-Pro press timing and call-control settings that live on the same screen.
Sort profiled devices into tiers (system-connected > nearby > cached), ordered by profile list within each tier. Collapse non-pinned cards to a compact battery tray with mini gauge rings matching the expanded card design. System-connected and top devices stay expanded; others can be tapped to toggle.
Split AapSessionEngine into dedicated controllers (AapAncController, AapOutboundController), a typed inbound decoder (AapInboundInterpreter), a HID frame batcher (HidTracker), and a device-info diagnostics helper (AapDeviceInfoDiagnostics). Each controller returns typed decisions carrying state, timer actions, and logs instead of mutating engine state via callbacks. AapSettingsCoordinator is now stateless — pending queue and verification state live in engine runtime state.
All coroutine timer Jobs live in the engine's timerJobs map keyed by EngineTimerKey, with cancelAllTimers() on reset to prevent forgotten cancellations. Engine event dispatch is split: suspend path for user-initiated sends (errors propagate to caller), non-suspend for sync events (timer fires, inbound updates).
Fix Elvis operator precedence bug in visibleAncModes() where OFF passed the filter unconditionally. Move filtering logic to PodDevice.visibleAncModes extension, unifying DualPodsCard, SinglePodsCard, and DeviceSettingsScreen. Gate AllowOffOption inference on pod-in-ear + 1.5s stability to prevent false positives from in-case OFF reports.
During case transitions, AirPods send 800+ cmd 0x0017 HID frames in ~20s. Previously each logged identically at VERBOSE with raw hex (~160KB noise). Now a HidTracker classifies frames (service directory, descriptor bulk, terminator) and batches consecutive bulk frames by (phase, fill), emitting 3-4 summary lines instead of 822.
Track lastAncSentAt separately so non-ANC commands during flush don't break the ANC echo debounce window. Prioritize ANC for post-flush verification.
Move HANDSHAKING→READY transition to top of processMessage so decoded battery, stem press, and device info messages also trigger it.
Sort flush: AllowOffOption before AncMode before others, preventing device rejection when enabling OFF mode.
Queue all setting commands when no pod is in ear, flush when a pod goes in. Enable the adaptive noise slider when ADAPTIVE mode is pending. Show an info box when settings changes are pending.
Extract AapSessionEngine (state, send path, message processing, inference) and AapSettingsCoordinator (queue, optimistic updates, verification) from AapConnection, reducing it from 773 to 173 lines.
Move serial, firmware, build, manufacturer, and per-pod serials from
the info card into a ModalBottomSheet triggered by an info icon.
Firmware+build and left+right pod serials render as paired rows.
Device info card: add model label with Apple model number, rename label to
Bluetooth Device Label, show cursive font on name mismatch with system BT
name, combine first/last seen on single row, add profile prefix to subtitle.
ANC mode: extract shared AncModeUi helpers for labels and icons, update
overview cards and device settings to use shared components.
Swap the logical mapping for `EndCallMuteMic` settings to align with hardware states observed on AirPods Pro devices. Updated session tests for Pro 1, 2, and 3 to reflect the corrected protocol behavior.
Based on Apple's official documentation, enable features for models
that support them per iOS but were previously excluded in CAPod:
- Gen 1/2: microphone mode (auto/left/right)
- Gen 3: press speed, press hold duration, tone volume, microphone mode
- Gen 4 non-ANC: press speed, press hold duration, tone volume
- Max original/USB-C: listening mode cycle, allow off option
Add SettingsInfoBox title support and experimental feature warning for Sleep Detection and Personalized Volume toggles with issue tracker action.
Pro-gate tone volume, microphone mode. Un-gate sleep detection, conversation awareness. Fix SettingsSwitchItem allowing direct switch toggle to bypass requiresUpgrade.
Older devices silently ignore the 0x4D packet, so there is no need to gate it per model. Sending it unconditionally prevents silent feature degradation when new H2+ models are added without the flag.
Remove needsInitExt from PodModel.Features.
Combine reaction one-pod mode (autoplay/autopause) and firmware NC-with-one-AirPod into one setting. The merged toggle always sets the app-local flag and additionally syncs the firmware NC setting via AAP when connected.
Also remove redundant @OptIn(ExperimentalCoroutinesApi::class) annotations from tests, already covered by the global compiler opt-in flag.
Real AirPod firmware silently drops writes with the LibrePods-documented 0x21 subtype. Switch to the compact 0x20 format that matches what devices actually emit in their echo frames. Also enforce the complementary-pair invariant at the SetEndCallMuteMic command boundary so validation runs before the optimistic UI update.
The encode/decode now flips UI 0..100 to wire 100..0. Update the clamp and decode expectations accordingly, and add a round-trip test to guard against asymmetric changes in either direction.
Switch the 0x4D init packet flags from 0x0E to 0xD7 to match the value captured from Apple's own stack (librepods AACPManager). The previous value traced to MagicPodsCore and matches no known Apple capture.
Invert the Adaptive Audio Noise level on write and read: wire 0 means max noise reduction, wire 100 means transparency-like. UI stays in intuitive 100 = max NC semantics, matching librepods' slider behavior.
