Android Android 上的蓝牙交叉传输密钥派生支持
Android Bluetooth Cross-Transport Key Derivation support on Android
Android是否正式支持 CTKD？来自 BlueZ documentation:
Another improvement that LE SC brings is what’s called cross-transport
key derivation. What this means is that when two dual-mode (supporting
LE + BR/EDR) devices pair with each other, they only need to pair over
either LE or BR/EDR to get the encryption keys for both transports in
one go.
我在官方 Android 文档中没有找到任何信息。
没有关于它的文档，但它是受支持的，请查看：
我能够触发 CTKD (BLE -> BR/EDR) 连接到 GATT (BluetoothDevice::connectGatt) 并且当连接状态变为 STATE_CONNECTED 然后触发配对请求 (BluetoothDevice::创建债券）。然后我与 BLE 配对，CTKD 生成 BR/EDR link 密钥。
