It’s a hands-on introduction to the invisible world of BLE — exactly the same technology behind contact tracing, asset trackers, and indoor navigation systems. No prior Bluetooth experience needed; just plug, code, and watch nearby beacons appear in real time.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA fully functional BLE Beacon Scanner that passively listens for advertising frames from devices like fitness bands, smart tags, and BLE sensors. The OLED screen scrolls live RSSI values and MAC addresses, turning your desk into a wireless monitoring station.
