Reverse engineering a Beyblade launch tracker
Summary
A detailed reverse-engineering write-up of a Beyblade launch tracker that analyzes how the Beybattle Pass Bluetooth device transmits launch data, decodes RPM values, and logs launches. The piece covers BLE sniffing, payload structure (a0, b0–b7, 70–73 pages), launch counters, and basic security/privacy observations, and it documents an AI/UI integration prototype called DiZZi with a GitHub project.
