Multi-Radio Flutter: Architecting Apps with UWB, BLE, and Beyond
summary
UWB provides centimeter-level ranging and angle data while BLE handles discovery and the secure token exchange, and Wi‑Fi Direct carries heavy payloads; BMW remote parking uses BLE for commands and UWB for a 6 m secure zone. Built a cross‑platform Flutter plugin (fork of a Christian Greiner proof) to unify discovery and handshakes, demo works but UWB drains ~20% battery in two hours and sessions last 2–3 minutes; watch for 20-byte BLE MTU, unreliable antennas, and platform SDK fragmentation.
