A journey in Android's BLE world
summary
Practical walkthrough of Android BLE behavior: permission splits (scan/advertise/connect), scanning quirks across OEMs, and why libraries smooth differences. Shows actual code patterns for scanning, filtering and connecting, using Nordic Semiconductor libraries and the Kotlin coroutines-based scanner, parsing raw characteristic bytes into booleans, and using DFU firmware updates for devices. Notes limits like about 20 connections per phone, unreliable background scans on many devices, and using iBeacon layout string or AltBeacon to range or monitor beacons for proximity and basic indoor positioning.
