Berjalan di Smartphone Android, bertugas mengelola koneksi ke sensor Polar (ECG), menerima data dari smartwatch (PPG), memproses sinyal, dan memvisualisasikannya di antarmuka utama (Dashboard). +* **`shared`**: Modul perpustakaan internal yang berisi kelas model data (seperti `PpgData`, `PpgType`), konstanta (`Constants.kt`), dan utilitas (*utils*) yang digunakan bersama oleh aplikasi mobile dan wear. + +## 3. Arsitektur dan Pipeline Sistem + +### A. Tahap Inisialisasi dan Koneksi +1. **Wear OS**: Saat aplikasi smartwatch dijalankan, ia melakukan inisialisasi `ConnectionManager` untuk terhubung ke infrastruktur **Samsung Health Tracking Service**. Aplikasi akan memverifikasi ketersediaan dan kapabilitas pelacakan optik (PPG Green, IR, Red) di jam tangan pengguna. Selain itu, ia juga menginisialisasi `GoogleApiClient` dengan layanan Google Play Services (`Wearable API`) untuk membentuk jaringan komunikasi dengan smartphone. +2. **Mobile**: Aplikasi smartphone diinisialisasi bersamaan dengan sebuah layanan *Foreground* (`MobileService`) yang terus menyala untuk mencegah OS mematikan proses perekaman di latar belakang. Aplikasi mengatur pencarian perangkat (`BluetoothService`) untuk memindai dan terhubung dengan sensor detak jantung Polar melalui BLE. Smartphone juga bertindak sebagai penerima (node) melalui Wearable API untuk merespons koneksi jam tangan. + +### B. Pipeline Aliran Data (Data Flow) +Proses transmisi data bergantung pada sumber sensornya: + +#### **Aliran Data PPG (Dari Wear ke Mobile)** +1. **Perekaman (Sampling)**: Sensor optik menangkap gelombang pantulan cahaya pada kulit lewat observer (`PpgGreenListener`, `PpgIrListener`, `PpgRedListener`). +2. **Batching (Pengumpulan)**: Karena frekuensi sampling (*sample rate*) cukup tinggi (puluhan data per detik), data akan diformat terlebih dahulu menggunakan `PpgRecording`. Pengiriman langsung (*streaming* tunggal) memakan banyak baterai, sehingga data ditampung secara lokal di smartwatch hingga mencapai batas *batch size* (misal: 100 data poin). +3. **Transmisi (Sinkronisasi)**: Setelah satu *batch* penuh, `MainActivity` di `wear` mengubahnya menjadi *string* JSON menggunakan `Gson`. Kemudian JSON dikirim secara instan ke aplikasi smartphone dengan status "Urgent" melalui **`Wearable.DataApi`** (`PutDataRequest`). +4. **Penerimaan**: Aplikasi `mobile` membaca perubahan pada jalur (*path*) data Wearable, menerima *payload* JSON, dan mengubahnya kembali menjadi objek `PpgData` yang siap untuk diproses dan di-plot. +5. **Flushing**: Apabila pengguna menghentikan proses perekaman, sistem smartwatch akan menjalankan instruksi `flushRemainingData()` agar memastikan setiap sisa titik data yang ada di *buffer* dipaksa dikirim agar tidak ada bagian grafik yang terpotong/hilang. + +#### **Aliran Data ECG & Heart Rate (Dari Polar ke Mobile)** +1. **Perekaman & Transmisi**: Sensor sentuh pada tali (*strap*) dada/lengan perangkat Polar merekam sinyal elektrik (ECG) dan mengirimkan titik datanya secara *real-time stream* ke `BluetoothService` di modul mobile melalui paket protokol standar BLE detak jantung. + +### C. Alur Pemrosesan dan Visualisasi +1. **Pemrosesan Sinyal**: Saat `mobile` menerima kumpulan data mentah dari sensor Wear OS dan Polar, alur diarahkan ke analisis algoritmis. Terdapat penerapan `QrsDetector` pada struktur file yang mengindikasikan bahwa sistem menggunakan metode matematis / pemfilteran batas *(threshold)* untuk mendeteksi gelombang kompleks QRS secara dinamis. +2. **Plotting / Visualisasi UI**: Agar interaksi grafis tidak menyebabkan HP macet (*hang*), komponen *Dashboard* di aplikasi mobile memisahkan tugas penggambarannya ke serangkaian modul `Plotter` yang diperbarui oleh *Thread / Scheduler* terpisah: + * `EcgPlotter.kt`: Membuat dan memperbarui kanvas grafik Elektrokardiogram. + * `PpgPlotter.kt`: Membuat kanvas visualisasi tiga kanal grafik cahaya optik PPG (Hijau, Merah, dan IR). + * `HrPlotter.kt` & `QrsPlotter.kt`: Memplot data agregat untuk denyut per menit (*Heart Rate*) serta visibilitas penanda puncak R. + +### D. Alur Kontrol dan Sinkronisasi Status +Proyek ini mengimplementasikan sinkronisasi state (status) menggunakan `Wearable.MessageApi`. +* Aplikasi *smartphone* memegang peranan sebagai *Remote Control*. Melalui aplikasi di HP, pengguna dapat memulai (*Start*), menghentikan (*Stop*), atau menjeda (*Pause*) perekaman. +* Pesan kontrol ini menyeberang lewat Bluetooth internal ke smartwatch. `MainActivity` smartwatch langsung membaca paket kontrol (berdasarkan `ActivityCode`) dan mengatur kondisi sensor Samsung (menyalakan tracker atau mematikannya). +* Pendekatan kontrol dua sisi ini menjamin bahwa tidak akan terjadi ketidaksesuaian sinkronisasi di mana smartwatch masih membakar baterai memancarkan laser optik ketika ponsel sudah berhenti mengumpulkan datanya. + +## 4. Kesimpulan +Basis kode **HeartRateMonitor** merupakan representasi luar biasa dari implementasi aplikasi biomedis yang terdistribusi (*distributed client-node*). Sistem ini menangani komplikasi perangkat keras dari dua produsen berbeda (Samsung dan Polar) dengan menciptakan "lem" integrasi mulus berupa protokol sinkronisasi batch Data API dan komunikasi BLE di *Foreground Service*. Pemisahan modul menjadi tiga segmen (*wear*, *mobile*, *shared*) memastikan stabilitas tinggi dan perawatan yang mudah dalam pengembangan *wearables* klinis/kesehatan secara mendalam. diff --git

Honor registration result; no Samsung connection requirement. | +| Watch PPG Green/IR/Red | One Samsung `PPG_CONTINUOUS` tracker with all three PPG types, **25 Hz each**, 300-sample batches. Only normal SDK status samples are accepted. | +| PPG channel controls | Phone status controls include/exclude individual channels from acquisition buffers within the active session. The shared hardware tracker remains active while any channel is enabled. | +| Polar connection | Manual device ID, Bluetooth permission/setup, connected/disconnected state, device name, firmware and battery information. | +| Polar ECG | Auto-start only after ECG capability readiness during an active session. H10 ECG uses 130 Hz; select/validate that rate for the QRS processor. | +| Polar HR/RR | Record SDK HR independently of ECG. Optional `rrsMs` already uses milliseconds; unavailable RR stays empty. Verity Sense must not be described as an ECG source. | +| Clock conversion | Watch PPG retains SDK Unix milliseconds. Native acceleration maps elapsed-realtime event timestamps to Unix milliseconds from a captured clock anchor. | +| ECG timing | Preserve per-sample Polar nanoseconds and gaps. Anchor the last sample of the first packet to phone receipt time once per subscription. Clear the anchor on resume/reconnect. | +| HR/RR timing | HR rows use notification receipt time. RR plot intervals are back-calculated from that receipt and the SDK millisecond intervals; never add an epoch timestamp as a time correction. | +| QRS analysis | Existing derivative/adaptive-threshold detector, R-peak markers and derived HR/RR. Peak indices continue to address the complete ECG recording after resume. No measured clinical accuracy claim. | +| Start/Pause/Resume/Stop | A fresh Start resets recordings; Pause drains buffered samples and unregisters sensors; Resume preserves session identity and existing data; Stop drains and ends acquisition. | +| Watch transport | Session ID, unique channel/session/batch paths, serialized uploads with retry, copied callback payloads, shape validation and duplicate suppression. Final counts cover Green/IR/Red/acceleration. | +| Transfer completion | Stop receipt and received counts must match before a Watch transfer is complete. Late flushes remain acceptable after pause/stop. Explicit partial export remains marked incomplete. | +| CSV export | SAF-selected directory and filename; ECG, each PPG channel, acceleration, Polar HR/RR, All PPG and All. Empty channels have zero rows, not padded samples. | +| Plotting | Separate ECG, Green/IR/Red, QRS and HR/RR graphs; pan while stopped, visibility/analysis preferences. Repeated redraw requests are coalesced through Choreographer. No measured 60 FPS claim. | +| Foreground lifecycle | Private declared phone/Watch services, ongoing notifications. Watch wake lock during active acquisition; sensors/wake lock released on pause, service retained for resume; Stop ends it after uploads drain. | +| Reconfiguration | Plot setup refresh preserves samples. Polar API restart/device ID change ends an active session before replacing the connection, retaining received recordings for export. | +| Settings/help | Device ID, plot/analysis visibility, configured preferences, SAF directory selection, device information and actionable in-app help. | +| Distribution | Matching versioned debug APKs, immutable release tags, direct phone/Watch download links, preserved historical releases; Samsung AAR stays local/ignored. | + +Samsung's old `PPG_IR`/`PPG_RED` types are on-demand measurements at 100 Hz. +They do not satisfy simultaneous continuous Green/IR/Red recording. Do not +reintroduce three independent trackers or label the continuous data 100 Hz. +Unsupported capability, permission/policy denial, missing sensors and +registration failures must remain visible unavailable/error states. + +ECG/HR clocks are receipt-anchored approximations: BLE delay and device clock +differences limit absolute alignment. Native accelerometer rate is requested, +not guaranteed; retain actual event times. Recording buffers live in memory. +Activity destruction ends acquisition; process-death recovery and durable +session storage are not implemented. The legacy ECG image helper has no active +export menu. Do not advertise inactive helper code as a delivered feature. + +## Non-negotiable requirements + +1. Values and timestamps correspond one-to-one. Only `size` samples may be + consumed, and invalid shapes, nonfinite acceleration, bad timestamp order + or mismatched PPG types must not crash ingestion or create substitute data. +2. All acquisition/buffer/control changes are serialized on the main looper; + SDK/Wearable callbacks copy payloads before leaving their owning callback. + Rendering is deferred/coalesced separately; throughput needs device testing. +3. Duplicate Start for the same active session is idempotent. Resume never + resets counters. Old session packets and duplicate unique batch keys do not + increase current counts. Callback generations suppress canceled listeners. +4. Stop/Pause unregister producers and snapshot/drain application buffers. + A stopped phone must continue to ingest the same session's late final data. + Do not mark transfer complete solely because a stop command was sent. +5. Device HR and QRS HR are distinct. Never gate real HR notifications on + `isEcgRunning`. ECG running means ECG data has actually arrived. +6. Preserve physical sample gaps; no sample-index clock substitution, stale + anchors, synthetic zeros or forced timestamps claiming exact synchronization. +7. A mandatory `setLocalTime` must not block ECG. Unsupported devices must + remain usable for their supported features. +8. SDK AARs, real session CSVs, APKs, keystores and credentials do not belong in + source commits. Publish only the requested APK assets; never rewrite history + or change upstream as a routine repair. + +## BDD acceptance and executable mapping -> **Architecture & Specification**: Dual-Module Vitals Tracking System (Samsung Galaxy Watch & Polar BLE Hub) -> **Development Methodology**: Spec-Driven Development (SDD), Behavior-Driven Development (BDD), BMAD & OpenSpec -> **Repository**: `HeartRateMonitor` (`Sample Wear Mobile App`) - ---- - -## 1.

Pendahuluan -Proyek **HeartRateMonitor** adalah sebuah sistem pelacakan tanda-tanda vital ganda (Dual-Module) berbasis Android yang terdiri dari aplikasi **Mobile (Smartphone)** dan **Wear OS (Smartwatch)**. Proyek ini bertujuan untuk merekam, menyinkronkan, memvisualisasikan, dan mengumpulkan data fisiologis secara *real-time*. +Current contract: [AGENTS.md](AGENTS.md). +Repair plan and validation receipts: [SENSOR_FIX_PLAN.md](SENSOR_FIX_PLAN.md). +Downloads/history: [README.md](README.md). -Sistem ini menggabungkan dua sumber sensor utama: -1. **Sensor PPG (Photoplethysmography)** dari Samsung Galaxy Watch (menggunakan Samsung Health SDK) untuk mengukur sirkulasi darah melalui sensor optik (Cahaya Hijau, Inframerah, dan Merah). -2. **Sensor ECG (Electrocardiogram)** dari perangkat eksternal Polar (misal: Polar H10 atau Verity Sense) yang dihubungkan ke smartphone melalui Bluetooth Low Energy (BLE). +The phone coordinates a session, receives Watch PPG/native motion, and connects +to supported Polar ECG/HR/RR features. Watch Green/IR/Red continuous acquisition +uses one Samsung tracker at 25 Hz, while H10 ECG uses 130 Hz. Device capability, +permission and SDK policy remain runtime gates. -## 2. Struktur Modul Proyek -Repositori proyek ini dipecah menjadi tiga modul Gradle utama: -* **`wear`**: Aplikasi Wear OS (Produsen Data). Berjalan di Samsung Galaxy Watch, bertugas merekam data PPG mentah beresolusi tinggi dan mengirimkannya ke smartphone. -* **`mobile`**: Aplikasi Android (Konsumen & Hub Data). Berjalan di Smartphone Android, bertugas mengelola koneksi ke sensor Polar (ECG), menerima data dari smartwatch (PPG), memproses sinyal, dan memvisualisasikannya di antarmuka utama (Dashboard). -* **`shared`**: Modul perpustakaan internal yang berisi kelas model data (seperti `PpgData`, `PpgType`), konstanta (`Constants.kt`), dan utilitas (*utils*) yang digunakan bersama oleh aplikasi mobile dan wear. +Version 1.3.0 repairs service registration, native motion independence, +pause/resume/drain semantics, unique/session-aware batch delivery, sample-clock +mapping, RR epoch correction, HR recording/export and frame redraw scheduling. +Raw acquisition is separate from the existing QRS heuristic and its derived HR. -## 3. Arsitektur dan Pipeline Sistem - -### A. Tahap Inisialisasi dan Koneksi -1. **Wear OS**: Saat aplikasi smartwatch dijalankan, ia melakukan inisialisasi `ConnectionManager` untuk terhubung ke infrastruktur **Samsung Health Tracking Service**. Aplikasi akan memverifikasi ketersediaan dan kapabilitas pelacakan optik (PPG Green, IR, Red) di jam tangan pengguna. Selain itu, ia juga menginisialisasi `GoogleApiClient` dengan layanan Google Play Services (`Wearable API`) untuk membentuk jaringan komunikasi dengan smartphone. -2. **Mobile**: Aplikasi smartphone diinisialisasi bersamaan dengan sebuah layanan *Foreground* (`MobileService`) yang terus menyala untuk mencegah OS mematikan proses perekaman di latar belakang. Aplikasi mengatur pencarian perangkat (`BluetoothService`) untuk memindai dan terhubung dengan sensor detak jantung Polar melalui BLE. Smartphone juga bertindak sebagai penerima (node) melalui Wearable API untuk merespons koneksi jam tangan. - -### B. Pipeline Aliran Data (Data Flow) -Proses transmisi data bergantung pada sumber sensornya: - -#### **Aliran Data PPG (Dari Wear ke Mobile)** -1. **Perekaman (Sampling)**: Sensor optik menangkap gelombang pantulan cahaya pada kulit lewat observer (`PpgGreenListener`, `PpgIrListener`, `PpgRedListener`). -2. **Batching (Pengumpulan)**: Karena frekuensi sampling (*sample rate*) cukup tinggi (puluhan data per detik), data akan diformat terlebih dahulu menggunakan `PpgRecording`. Pengiriman langsung (*streaming* tunggal) memakan banyak baterai, sehingga data ditampung secara lokal di smartwatch hingga mencapai batas *batch size* (misal: 100 data poin). -3. **Transmisi (Sinkronisasi)**: Setelah satu *batch* penuh, `MainActivity` di `wear` mengubahnya menjadi *string* JSON menggunakan `Gson`. Kemudian JSON dikirim secara instan ke aplikasi smartphone dengan status "Urgent" melalui **`Wearable.DataApi`** (`PutDataRequest`). -4. **Penerimaan**: Aplikasi `mobile` membaca perubahan pada jalur (*path*) data Wearable, menerima *payload* JSON, dan mengubahnya kembali menjadi objek `PpgData` yang siap untuk diproses dan di-plot. -5. **Flushing**: Apabila pengguna menghentikan proses perekaman, sistem smartwatch akan menjalankan instruksi `flushRemainingData()` agar memastikan setiap sisa titik data yang ada di *buffer* dipaksa dikirim agar tidak ada bagian grafik yang terpotong/hilang. - -#### **Aliran Data ECG & Heart Rate (Dari Polar ke Mobile)** -1. **Perekaman & Transmisi**: Sensor sentuh pada tali (*strap*) dada/lengan perangkat Polar merekam sinyal elektrik (ECG) dan mengirimkan titik datanya secara *real-time stream* ke `BluetoothService` di modul mobile melalui paket protokol standar BLE detak jantung. - -### C. Alur Pemrosesan dan Visualisasi -1. **Pemrosesan Sinyal**: Saat `mobile` menerima kumpulan data mentah dari sensor Wear OS dan Polar, alur diarahkan ke analisis algoritmis. Terdapat penerapan `QrsDetector` pada struktur file yang mengindikasikan bahwa sistem menggunakan metode matematis / pemfilteran batas *(threshold)* untuk mendeteksi gelombang kompleks QRS secara dinamis. -2. **Plotting / Visualisasi UI**: Agar interaksi grafis tidak menyebabkan HP macet (*hang*), komponen *Dashboard* di aplikasi mobile memisahkan tugas penggambarannya ke serangkaian modul `Plotter` yang diperbarui oleh *Thread / Scheduler* terpisah: - * `EcgPlotter.kt`: Membuat dan memperbarui kanvas grafik Elektrokardiogram. - * `PpgPlotter.kt`: Membuat kanvas visualisasi tiga kanal grafik cahaya optik PPG (Hijau, Merah, dan IR). - * `HrPlotter.kt` & `QrsPlotter.kt`: Memplot data agregat untuk denyut per menit (*Heart Rate*) serta visibilitas penanda puncak R. - -### D. Alur Kontrol dan Sinkronisasi Status -Proyek ini mengimplementasikan sinkronisasi state (status) menggunakan `Wearable.MessageApi`. -* Aplikasi *smartphone* memegang peranan sebagai *Remote Control*. Melalui aplikasi di HP, pengguna dapat memulai (*Start*), menghentikan (*Stop*), atau menjeda (*Pause*) perekaman. -* Pesan kontrol ini menyeberang lewat Bluetooth internal ke smartwatch. `MainActivity` smartwatch langsung membaca paket kontrol (berdasarkan `ActivityCode`) dan mengatur kondisi sensor Samsung (menyalakan tracker atau mematikannya). -* Pendekatan kontrol dua sisi ini menjamin bahwa tidak akan terjadi ketidaksesuaian sinkronisasi di mana smartwatch masih membakar baterai memancarkan laser optik ketika ponsel sudah berhenti mengumpulkan datanya. - -## 4. Kesimpulan -Basis kode **HeartRateMonitor** merupakan representasi luar biasa dari implementasi aplikasi biomedis yang terdistribusi (*distributed client-node*). Sistem ini menangani komplikasi perangkat keras dari dua produsen berbeda (Samsung dan Polar) dengan menciptakan "lem" integrasi mulus berupa protokol sinkronisasi batch Data API dan komunikasi BLE di *Foreground Service*. Pemisahan modul menjadi tiga segmen (*wear*, *mobile*, *shared*) memastikan stabilitas tinggi dan perawatan yang mudah dalam pengembangan *wearables* klinis/kesehatan secara mendalam. +Receipts, software test counts and lint warnings must be read from the selected +repair evidence. No physical Watch/H10 acquisition, fixed frame rate, clinical +accuracy or exact inter-device synchronization result is claimed. diff --git a/shared/build.gradle b/shared/build.gradle index de428a2..25a6eee 100644 --- a/shared/build.gradle +++ b/shared/build.gradle @@ -11,4 +11,8 @@ dependencies { java { sourceCompatibility = JavaVersion.VERSION_1_8 targetCompatibility = JavaVersion.VERSION_1_8 -} \ No newline at end of file +} + +tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach { + kotlinOptions.jvmTarget = '1.8' +} diff --git a/wear/src/main/java/com/example/samplewearmobileapp/AccelerometerRecording.kt b/shared/src/main/java/com/example/samplewearmobileapp/AccelerometerRecording.kt similarity index 89% rename from wear/src/main/java/com/example/samplewearmobileapp/AccelerometerRecording.kt rename to shared/src/main/java/com/example/samplewearmobileapp/AccelerometerRecording.kt index 1b73194..4a6c3c2 100644 --- a/wear/src/main/java/com/example/samplewearmobileapp/AccelerometerRecording.kt +++ b/shared/src/main/java/com/example/samplewearmobileapp/AccelerometerRecording.kt @@ -1,6 +1,5 @@ package com.example.samplewearmobileapp -import android.util.Log class AccelerometerRecording { val xValues = mutableListOf() @@ -23,7 +22,6 @@ class AccelerometerRecording { if (zValues.isNotEmpty()) zValues.removeAt(0) if (timestamps.isNotEmpty()) timestamps.removeAt(0) } - Log.i("Wear: AccRecording", "Cleared $toRemove items.
