This commit introduces a new `BatteryState` data class and an extension function `ProximityPayload.Private.asBatteryState` to simplify the parsing of battery level and charging status from the proximity payload.
The `asBatteryState` function takes the position of the battery data in the payload and returns a `BatteryState` object, or null if the data is invalid.
This change improves code readability and maintainability by encapsulating the battery state parsing logic.
The previous logic for determining if the case was charging relied on the `batteryCasePercent` being non-null. This commit refines the logic to check if the `batteryCasePercent` falls within the valid range of 0.0 to 1.0, providing a more accurate assessment of the case's charging status.
This moves the history tracking logic for discovered Apple Pods from individual `ApplePodsFactory` implementations to a new `PodHistoryRepo` class.
Benefits:
- Centralized logic for device history management.
- Simplifies individual `ApplePodsFactory` implementations.
- Improves code maintainability and testability.
Relocate RPAChecker to the `pods.core.apple.protocol` package as it's specific to Apple's protocol.
Introduce type aliases `IdentityResolvingKey` and `ProximityEncryptionKey` for `ByteArray` to improve code clarity and type safety when dealing with these keys. Update relevant classes to use these new type aliases.
This commit introduces a typealias `BluetoothAddress` for `String` to improve code clarity and type safety when dealing with Bluetooth MAC addresses.
The following changes were made:
- Created `BluetoothAddress.kt` defining the typealias.
- Updated various classes to use `BluetoothAddress` instead of `String` for Bluetooth addresses:
- `RPAChecker`
- `PopUpReaction`
- `DeviceSelectionDialogFactory`
- `MonitorWorker`
- `GeneralSettings`
- `BluetoothDevice2`
This commit introduces a new helper function `fromHex()` that converts a HEX string (with optional separators like spaces or hyphens) into a byte array. It also adds a corresponding `toHex()` function for converting a byte array to a HEX string.
These helpers are now used in various parts of the codebase, including:
- Fake BLE data generation
- AirPod key input dialog
- RPA checker tests
- BaseAirPodsTest
Additionally, a unit test for these conversion functions has been added.
This commit adds a test case to `AirPodsProTest` to verify the decryption of AirPods Pro data with and without encryption/IRK keys. It also introduces a new test class `RPACheckerTest` to validate the RPA checking mechanism.
Helper functions for converting hex strings to byte arrays and setting mock keys have been added to `BaseAirPodsTest` to simplify test setup.
This change introduces the capability to decrypt the last 16 bytes of the proximity pairing message if an encryption key is available.
The decrypted payload provides more precise battery information (0-100% instead of 0-10%) and charging status for each pod and the case.
This information is now used by `DualApplePods` to enhance battery reporting accuracy.
The `RPAChecker` has also been updated with improved error logging.
Replace `values()` with `entries` for enum iteration, as recommended by Kotlin for improved performance and consistency.
Also:
- Suppress unused warning in `ByteArrayAdapter`
- Improve logging in `WebpageTool` by including the exception details.
This commit introduces settings for users to input their AirPods' Identity Resolving Key (IRK) and Encryption Key. These keys, obtainable via a MacBook, allow CAPod to reliably identify the AirPods and decrypt detailed status information.
Key changes:
- Added new preferences in General Settings for IRK and Encryption Key.
- Implemented a custom dialog for key input, including validation and a link to a guide.
- Added a Moshi adapter for serializing/deserializing `ByteArray` to/from Base64 for storing the keys.
- Included new string resources for labels, descriptions, and explanations related to the keys.
- Added new icons for the key preferences.
