Bluetooth + Kotlin: It's a Match!
summary
Empatica starts building an EmbracePlus SDK in January 2020 and after two years ships a Bluetooth stack with 100% Kotlin and Kotlin Multiplatform reuse plus Compose in production; code uses a threaded Handler to serialize GATT writes, adds CRC checks for corrupted packets, and logs network type after discovering a phone that corrupts Bluetooth on 2.4GHz. Debugging relies on Bluetooth packet captures (developer setting → Wireshark), ADB over Wi‑Fi and Visor for remote devices, and explicit handling for Android 12/13 Bluetooth permissions.
