在Android中获取BLE Beacon的Tx能力

BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (bluetoothAdapter == null || !bluetoothAdapter.isEnabled()) {
    // 蓝牙不可用，需要请求用户授权打开蓝牙
    Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
    startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}

bluetoothAdapter.startLeScan(leScanCallback);

private BluetoothAdapter.LeScanCallback leScanCallback = new BluetoothAdapter.LeScanCallback() {
    @Override
    public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) {
        // 处理扫描到的BLE设备信息
        if (device.getName() != null && device.getName().equals("BLE Beacon")) {
            // 获取BLE Beacon的Tx能力
            int txPowerLevel = scanRecord[29];
            // 处理获取到的Tx能力
            // ...
        }
    }
};
