Concrete steps and working code for Bluetooth Low Energy in React Native using react-native-ble-plx: monitor adapter state, filter for powered on, startDeviceScan and flatten streams, discover services and characteristics before access, and turn arrays into streams. It uses streams (xstream-style) plus hooks to bind values, shows combine to pair commands with a write characteristic, handles base64 encoding and DataView parsing, reports seeing 50–60 characteristics on a device, and demos a BB‑8 robot controller with collision detection; code is on GitHub.
