+# WebSocket IPC API
+
+This document describes how to communicate with the OpenWearable WebSocket connector.
+
+Python clients can use the [`open-wearables`](https://pypi.org/project/open-wearables/)
+package instead of implementing the JSON WebSocket protocol directly.
+
+## Endpoint
+
+Default endpoint:
+
+- `ws://<device-ip>:8765/ws`
+
+Notes:
+
+- The app binds the websocket server on all IPv4 interfaces and advertises the current device IP for clients on the same network.
+- Port and path are configurable in app settings.
+- The API is JSON over WebSocket text frames.
+
+## Message Envelopes
+
+Request:
+
+```json
+{"id":1,"method":"ping","params":{}}
+```
+
+Success response:
+
+```json
+{"id":1,"result":{"ok":true}}
+```
+
+Error response:
+
+```json
+{
+  "id": 1,
+  "error": {
+    "message": "Unknown method: foo",
+    "type": "UnsupportedError",
+    "stack": "..."
+  }
+}
+```
+
+## Server Events
+
+On connect, the server sends:
+
+```json
+{
+  "event": "ready",
+  "methods": ["ping", "methods", "..."],
+  "endpoint": "ws://192.168.1.23:8765/ws"
+}
+```
+
+`ready.endpoint` may be `null` when the app cannot determine a client-reachable
+LAN IP address. The connector still runs in that case.
+
+Other event messages:
+
+- `scan`: broadcast when a device is discovered.
+- `connecting`: broadcast when a connect attempt starts.
+- `connected`: broadcast when a wearable is connected.
+- `stream`: stream subscription data.
+- `stream_error`: error for a stream subscription.
+- `stream_done`: stream finished.
+
+`stream` event format:
+
+```json
+{
+  "event": "stream",
+  "subscription_id": 1,
+  "stream": "sensor_values",
+  "device_id": "string",
+  "data": {}
+}
+```
+
+## Top-Level Methods
+
+| Method | Params | Result |
+|---|---|---|
+| `ping` | `{}` | `{"ok":true}` |
+| `methods` | `{}` | `string[]` |
+| `has_permissions` | `{}` | `bool` |
+| `check_and_request_permissions` | `{}` | `bool` |
+| `start_scan` | `{"check_and_request_permissions"?:bool}` | `{"started":true}` |
+| `start_scan_async` | `{"check_and_request_permissions"?:bool}` | `{"started":true,"subscription_id":int,"stream":"scan","device_id":"scanner"}` |
+| `get_discovered_devices` | `{}` | `DiscoveredDevice[]` |
+| `connect` | `{"device_id":string,"connected_via_system"?:bool}` | `WearableSummary` |
+| `connect_system_devices` | `{"ignored_device_ids"?:string[]}` | `WearableSummary[]` |
+| `list_connected` | `{}` | `WearableSummary[]` |
+| `disconnect` | `{"device_id":string}` | `{"disconnected":true}` |
+| `store_sound` | `{"sound_id":string,"audio_base64":string,"codec"?:string,"sample_rate"?:int,"num_channels"?:int,"interleaved"?:bool,"buffer_size"?:int}` | `{"sound_id":string,"stored":true,"bytes":int,"config":object}` |
+| `play_sound` | `{"sound_id":string,"volume"?:number,"codec"?:string,"sample_rate"?:int,"num_channels"?:int}` | `{"source":"sound_id","sound_id":string,"playing":true,"config":object}` |
+| `subscribe` | `{"device_id":string,"stream":string,"args"?:object}` | `{"subscription_id":int,"stream":string,"device_id":string}` |
+| `unsubscribe` | `{"subscription_id":int}` | `{"subscription_id":int,"cancelled":bool}` |
+| `invoke_action` | `{"device_id":string,"action":string,"args"?:object}` | depends on action |
+
+## Action Commands (`invoke_action`)
+
+Current actions:
+
+- `disconnect` (no `args`)
+- `synchronize_time`
+- `list_sensors`
+- `list_sensor_configurations`
+- `set_sensor_configuration` with args:
+  - `{"configuration_name":string,"value_key":string}`
+
+Examples:
+
+```json
+{"id":10,"method":"invoke_action","params":{"device_id":"abc","action":"synchronize_time"}}
+```
+
+```json
+{"id":11,"method":"invoke_action","params":{"device_id":"abc","action":"set_sensor_configuration","args":{"configuration_name":"Accelerometer","value_key":"100Hz"}}}
+```
+
+## Subscribe Streams
+
+Supported values for `subscribe.params.stream`:
+
+- `sensor_values` (requires one of below in `args`)
+  - `{"sensor_id":string}` (recommended)
+  - `{"sensor_index":int}`
+  - `{"sensor_name":string}`
+- `sensor_configuration`
+- `button_events`
+- `battery_percentage`
+- `battery_power_status`
+- `battery_health_status`
+- `battery_energy_status`
+
+Note:
+
+- `scan` is not a direct `subscribe` stream.
+- Use `start_scan_async` to receive scan data via `stream` events.
+
+## Audio Playback Over WebSocket
+
+The connector supports distinct preloaded sounds (store once, play many times).
+
+### 1) Distinct Preloaded Sounds
+
+Store sound bytes in memory:
+
+```json
+{
+  "id": 20,
+  "method": "store_sound",
+  "params": {
+    "sound_id": "beep_ok",
+    "audio_base64": "<base64-encoded-audio-bytes>"
+  }
+}
+```
+
+Play a stored sound:
+
+```json
+{
+  "id": 21,
+  "method": "play_sound",
+  "params": {
+    "sound_id": "beep_ok",
+    "volume": 1.0
+  }
+}
+```
+
+`play_sound` requires `sound_id`.
+
+## Data Shapes
+
+### DiscoveredDevice
+
+```json
+{
+  "id": "string",
+  "name": "string",
+  "service_uuids": ["string"],
+  "manufacturer_data": [1, 2, 3],
+  "rssi": -56
+}
+```
+
+### WearableSummary
+
+```json
+{
+  "device_id": "string",
+  "name": "string",
+  "type": "OpenEarableV2",
+  "capabilities": ["SensorManager", "SensorConfigurationManager"]
+}
+```
+
+### `list_sensors` item
+
+```json
+{
+  "sensor_id": "accelerometer_0",
+  "sensor_index": 0,
+  "name": "Accelerometer",
+  "chart_title": "Accelerometer",
+  "short_chart_title": "ACC",
+  "axis_names": ["x", "y", "z"],
+  "axis_units": ["m/s²", "m/s²", "m/s²"],
+  "timestamp_exponent": -9
+}
+```
+
+### `list_sensor_configurations` item
+
+```json
+{
+  "name": "Accelerometer",
+  "unit": "Hz",
+  "values": [
+    {
+      "key": "100Hz",
+      "frequency_hz": 100,
+      "options": ["streamSensorConfigOption"]
+    }
+  ],
+  "off_value": "off"
+}
+```
+
+## Suggested Workflows
+
+### Scan and connect
+
+1. Call `start_scan` or `start_scan_async`.
+2. Use `get_discovered_devices` (or consume stream events from `start_scan_async`).
+3. Call `connect` with selected `device_id`.
+
+### Sensor streaming
+
+1. `invoke_action` with `action="list_sensors"`.
+2. Pick `sensor_id`.
+3. `subscribe` with `stream="sensor_values"` and `args={"sensor_id":"..."}`.
+4. `unsubscribe` when done.
+
+### Distinct sound playback
+
+1. `store_sound` with `sound_id` and `audio_base64`.
+2. `play_sound` with the same `sound_id`.
