Great reverse engineering work! The Kindle's Bluetooth implementation has always been frustratingly limited - only supporting Amazon's official accessories despite having the hardware capability for much more.

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.
