Case study

Chronos Revived: an Android client for the recovered smart disc BLE protocol

Chronos Revived replaces the discontinued Android companion app for the Chronos smart disc using its recovered Bluetooth LE protocol. It handles notifications, steps, battery status and gestures, and can flash firmware supplied from the user's original APK. The protocol notes map GATT services, status bits, commands and device hardware identified from firmware analysis.
