First request the tenant’s sensors. Keep each device UUID, name and type. Show relay controls only when the backend device type is relay. Normalize UUIDs to lowercase hexadecimal without separators before comparing them.

Skannaa ja tunnista fyysinen laite

Scan continuously with duplicate advertisements while the device screen is visible. Use one application-wide scan owner because mobile BLE libraries commonly expose only one native scan.

1. Request the platform’s Bluetooth scan and connect permissions, then start a low-latency scan.
2. Accept the name SVN, but do not require it: Android may omit the local name.
3. Recognize manufacturer ID 0x79fd. Build the primary eight-byte UUID from that ID in little-endian order followed by the first six manufacturer payload bytes.
4. Match the normalized result with backend inventory, retain the native BLE device ID and RSSI, and remove nearby state after 10 seconds without an advertisement.

After the user confirms the target and physical action, request a complete node-core package for the device. Both relays and smart locks can provide packages for direct delivery. HTTP 200 means package generated only; it does not mean delivered or executed.

{
  "operation": "pulse",
  "value": 5,

}

{
  "operation": "consumption",
  "kwh": 1.5
}

Pulse requires a positive value and milliseconds, seconds or minutes. Consumption requires kwh. Decode either packageBase64 or packageHex—not both—and require exactly 212 bytes. Never modify or log those bytes.

Siirrä paketti BLE:n kautta

Use the most recently seen native BLE device ID. Display a blocking progress overlay, stop scanning, clear a stale connection, connect and discover the exact node-core GATT service and write characteristic.

1. Decode one package representation and verify that it is exactly 212 bytes.
2. Read the negotiated MTU when available and calculate an MTU-safe chunk size.
3. Write chunks sequentially in their original order. Prefer write without response when the characteristic supports it.
4. After every chunk succeeds, disconnect in a final cleanup path. Never automatically retry a physical operation after delivery started.
5. Resume continuous scanning after a short settling interval if the screen remains open.

chunkSize = max(20, min(215, negotiatedMtu - 3))
fallbackChunkSize = 20

Completing all writes proves transport completion, not necessarily physical execution. Use a device acknowledgement or observed state when available.

• check_circleReport “Package transferred successfully” when BLE transport completes.
• check_circleReport physical completion only when the device or observed state confirms it.
• check_circleLog lifecycle stages and chunk lengths, but never tokens, package bytes, credentials or decoded payloads.
