The Bluetooth functionality this project targets is available since the 11th generation Kindles (KT5, PW5). As of now, this project is just targeting HF (Hard Float) Kindle firmwares (version 5.16.3 and up). SF (Soft Float) firmwares are technically possible to support but out of scope for now.

Since the 11th generation, Amazon seems to have switched to Bluedroid for their Bluetooth stack (10th gen seems to have used BlueZ). On top of it, they have their own closed-source Bluetooth stack abstraction ace_bt. They have built their own closed-source server btmanagerd, which uses ace_bt and other proprietary libraries.

There is basically no documentation for ace_bt and the different Bluetooth components on Kindles. That's why this library, kindlebt, will be our wrapper around it, providing a simpler and documented interface that can be used from applications and from other languages.
