Nice write-up. Bluetooth on Kindle always felt like a black box, and this does a great job of peeling it open layer by layer. The mix of firmware analysis, protocol reverse engineering, and practical constraints of embedded devices is especially useful. Also a good reminder of how much attack surface quietly lives in “secondary” features like Bluetooth that most users never think about.
It's interesting to see the protocol layers exposed. This could potentially enable custom keyboard support or even audio output if someone takes it further. Amazon intentionally locks down these devices to push their ecosystem, but the hardware is perfectly capable.
Would be curious to see if this could enable BLE-based automations or integrations with reading tracking apps. The closed nature of Kindle has always been its biggest weakness.
