### Bluetooth Low Energy (BLE)
-The BLE stack uses a hybrid interface-driven architecture. Platform-agnostic interfaces live in `commonMain`, while the Android implementation utilizes **Nordic Semiconductor's Kotlin BLE Library**. This provides a robust, Coroutine-based architecture for reliable device communication while remaining KMP compatible. See [core/ble/README.md](core/ble/README.md) for details.
+The BLE stack uses a multiplatform interface-driven architecture. Platform-agnostic interfaces live in `commonMain`, utilizing the **Kable** multiplatform BLE library to handle device communication across all supported targets (Android, Desktop). This provides a robust, Coroutine-based architecture for reliable device communication while remaining fully KMP compatible. See [core/ble/README.md](core/ble/README.md) for details.

+# Specification: Replace Nordic with Kable on Android (Deduplication Pass)
+
+## Overview
+This track executes a full migration of the Android application's BLE transport layer from the legacy Nordic Android Common Libraries to the multiplatform Kable library. Building upon the successful `MeshtasticRadioProfile` abstraction introduced for the Desktop target, this track aims to unify the BLE transport layer across all platforms (Android, Desktop, iOS) under a single KMP technology stack. Crucially, this pass focuses on **maximal code deduplication**, moving as much BLE logic as possible into `commonMain` to share it across all targets, including OTA firmware update logic.
+
+## Functional Requirements
+- **Kable Integration:** Implement the `MeshtasticRadioProfile` using Kable for the `androidMain` source set, replacing the existing Nordic implementation.
+- **Maximal Deduplication:** Refactor the existing Kable `jvmMain` implementation and the new `androidMain` implementation to extract common connection management, scanning logic, and characteristic observation into `core:ble/commonMain`.
+- **OTA Firmware Updates:** Migrate the Android OTA firmware update logic (currently handled by `NordicDfuHandler`) to use the new Kable/KMP abstraction.
+- **Full Migration:** The Android app must exclusively use the new Kable backend for all BLE operations (scanning, connecting, data transfer, firmware updates).
+- **Deprecation/Removal:** Remove all dependencies on the Nordic Android Common Libraries and Nordic DFU libraries from the project configuration (`build.gradle.kts`, version catalogs).
+- **Feature Parity:** The new Kable implementation on Android must maintain full feature parity with the previous Nordic implementation, including connection stability, MTU negotiation, and data throughput.
+
+## Non-Functional Requirements
+- **Expanded Testing:** Adapt existing Android BLE tests to use Kable fakes and write new `commonMain` tests to expand test coverage for the shared KMP BLE abstraction.
+- **Architecture:** Maintain strict adherence to the MVI/UDF patterns and the pure KMP DI architecture (Koin annotations).
+
+## Acceptance Criteria
+- [ ] Kable backend is fully implemented for Android (`androidMain`).
+- [ ] Nordic Android Common Libraries and DFU dependencies are completely removed from the project.
+- [ ] Android application successfully scans, connects, and transfers data via BLE using Kable.
+- [ ] BLE logic (connection state, profile mapping, retry logic) is heavily deduplicated into `core:ble/commonMain`.
+- [ ] OTA firmware update logic is successfully migrated to use the Kable backend.
+- [ ] Existing BLE tests are updated or replaced, and all test suites pass.
+- [ ] New KMP BLE tests are added, improving overall test coverage.
+
+## Out of Scope
+- Migrating USB or TCP network transports.

+# Specification: Desktop BLE Enablement via Kable
+
+## Overview
+This track introduces a Kable BLE backend specifically for the `jvmMain` (Desktop) target within `core:ble`. To facilitate this without breaking the existing Android implementation, we will introduce a `MeshtasticRadioProfile` abstraction in `core:ble/commonMain`. This abstraction will ensure that the app-level BLE transport path no longer depends on Android-specific or Nordic-specific classes. Initially, Android will continue to use the Nordic BLE implementation, while Desktop will use Kable. Once this seam is proven, a future decision will determine whether Android should fully migrate to Kable. This approach lays the groundwork for seamless integration of future targets (e.g., iOS) under the same KMP abstraction.
+
+## Functional Requirements
+- **MeshtasticRadioProfile Abstraction:** Introduce a multiplatform interface (`MeshtasticRadioProfile`) in `core:ble/commonMain` to abstract all BLE operations.
+- **Remove Nordic Dependencies:** Ensure that the app-level BLE transport path is entirely decoupled from Nordic types, relying solely on the new abstraction.
+- **Kable Backend (jvmMain):** Implement the Kable backend for the Desktop target. This backend must support all core BLE operations:
+ - Scanning for nearby Meshtastic devices.
+ - Establishing and managing BLE connections.
+ - Reading from and writing to characteristics (sending/receiving protobuf payloads).
+- **Nordic Backend Preservation (androidMain):** Update the existing Android Nordic implementation to implement the new `MeshtasticRadioProfile` interface without changing its core behavior.
+- **Future-Proofing:** Design the abstraction in a way that is generic enough to support adding an iOS or other future target's BLE implementation with minimal refactoring.
+
+## Non-Functional Requirements
+- **Testing:** New `commonMain` unit tests must be written utilizing fakes for the Kable implementation. This is crucial as we cannot rely on Nordic's ready-made mocks in a multiplatform context or if a full migration to Kable occurs.
+- **Architecture:** The abstraction must adhere to the project's KMP goals, keeping `core:ble/commonMain` completely free of platform-specific imports (e.g., `java.*`, `android.*`).
+- **Compatibility:** The Android build and BLE functionality must remain fully functional using the existing Nordic library.
+
+## Acceptance Criteria
+- [ ] `MeshtasticRadioProfile` is defined in `core:ble/commonMain`.
+- [ ] No Nordic-specific or Android-specific types are present in the app-level BLE transport path.
+- [ ] Desktop application can successfully scan, connect, and perform read/write operations with a Meshtastic device using Kable.
+- [ ] Android application continues to function normally using the Nordic library.
+- [ ] New unit tests using Kable fakes are added to `commonMain` and pass successfully.
+- [ ] The abstraction architecture provides a clear path for future platform support (like iOS).
+
+## Out of Scope
+- Migrating the Android application to use the Kable backend (this will be evaluated after this track is complete).
+- Modifying non-BLE network transports (e.g., USB, TCP).

# Decision: BLE KMP Strategy
-> Date: 2026-03-10 | Status: **Decided — Phase 1 complete**
+> Date: 2026-03-16 | Status: **Decided — Fully Migrated to Kable**
## Context
-`core:ble` needed to support non-Android targets. Nordic's KMM-BLE-Library is Android/iOS only (no Desktop/Web). KABLE supports all KMP targets but lacks mock modules.
+`core:ble` needed to support non-Android targets. Nordic's Kotlin-BLE-Library, while mature on Android and actively tested in the app, was primarily Android/iOS focused and lacked support for Desktop (JVM) targets. Kable natively supports all Kotlin Multiplatform targets (Android, Apple, Desktop/JVM, Web).
+
+Initially, we implemented an **Interface-Driven "Nordic Hybrid" Abstraction** (keeping Nordic on Android behind `commonMain` interfaces) to wait and see if Nordic expanded their KMP support.
+
+However, as Desktop integration advanced, we found the need for a unified BLE transport.
## Decision
-**Interface-Driven "Nordic Hybrid" Abstraction:**
+**Migrate entirely to Kable:**
-- `commonMain`: Pure Kotlin interfaces (`BleConnection`, `BleScanner`, `BleDevice`, `BleConnectionFactory`, etc.) — zero platform imports
-- `androidMain`: Nordic KMM-BLE-Library implementations behind those interfaces
-- `jvm()` target added — interfaces compile fine; no JVM BLE implementation needed yet
-- Future: KABLE or alternative can implement the same interfaces for Desktop/iOS without touching core logic

-**BLE library decision: Stay on Nordic, wait.** Our abstraction layer is clean — switching backends later is a bounded, mechanical task (~6 files, ~400 lines). Nordic is actively developing. We don't currently need real BLE on JVM/iOS. If Nordic hasn't shipped KMP by the time we need iOS, revisit KABLE.
+- We migrated all BLE transport logic across Android and Desktop to use Kable.
+- The `commonMain` interfaces (`BleConnection`, `BleScanner`, `BleDevice`, `BluetoothRepository`, etc.) remain, but their core implementations (`KableBleConnection`, `KableBleScanner`) are now entirely shared in `commonMain`.
+- The Android-specific Nordic dependencies (`no.nordicsemi.kotlin.ble:*`) and the Nordic DFU library were completely excised from the project.
+- OTA Firmware updates on Android were successfully refactored to use the Kable-based `BleOtaTransport`.
## Consequences
-- `core:ble` compiles on JVM and is included in CI smoke compile
-- No Nordic types leak into `commonMain`
-- Desktop simply doesn't inject BLE bindings
-- Migration cost to KABLE is predictable and bounded
+- **Maximal Code Deduplication:** The BLE implementation is completely shared across Android and Desktop in `core:ble/commonMain`.
+- **Future-Proofing:** Adding an `iosMain` target in the future will be trivial, as it can leverage the same shared Kable abstractions.
+- **Lost Nordic Mocks:** Kable lacks the comprehensive mock infrastructure of the Nordic library. Consequently, several complex BLE OTA unit tests had to be deprecated. Re-establishing this test coverage using custom Kable fakes is an ongoing technical debt item.
