🔧 Technical Implementation

How Multi-Beacon Detection Works:

1. Continuous Scanning

App scans for beacons every 1 second, maintains list of all detected beacons with RSSI values

2. Distance Calculation

Using RSSI and TX Power: Distance = 10^((TX Power - RSSI) / (10 * N)) where N = 2 (path loss)

3. Smart Sorting Algorithm

Priority: 1) Distance (nearest first), 2) License status (expired/none higher), 3) Last inspection date

4. Real-time Updates

List updates as inspector moves, beacons appear/disappear based on signal strength

5. Batch API Calls

Send all beacon IDs in one request: POST /api/premises/batch with array of minor IDs

✅ Benefits of This Approach:

Inspector can quickly see which premises need urgent attention
No need to walk around searching - all info at fingertips
Prioritize expired licenses or unlicensed premises
Efficient route planning based on proximity
Works even in crowded areas with 50+ beacons
