Wireless protocols for the next generation IoT devices
summary
Compares 2.4 GHz Wi‑Fi and Bluetooth: Wi‑Fi uses wide channels for higher throughput while Bluetooth does frequency hopping for robustness, hence lower speed. Shows Android specifics: use DPP easy connect (Android 10+) to provision Wi‑Fi via QR URI, acquire Wi‑Fi full/low latency and multicast locks, and prefer Cable for BLE. Recommends setting autoconnect false, requesting MTU on services discovered, using L2CAP for streaming, notes LoRa tests of 13–15 km and UWB giving centimeter‑level ranging with out‑of‑band Bluetooth key exchange.
