Question

我正在创建一个应用程序，我想要当我点击扫描按钮时它只扫描BLE而不是Android手机的蓝牙，所以是否有任何权限或依赖关系只扫描BLE不是中心。

您可以尝试这样做以避免电话：

    if (device.getBluetoothClass().getMajorDeviceClass() != BluetoothClass.Device.Major.PHONE) {
        // do something
    }

请参阅BluetoothClass.Device.Major并选择您想要的内容

    public static class Major {
        private static final int BITMASK           = 0x1F00;
        public static final int MISC              = 0x0000;
        public static final int COMPUTER          = 0x0100;
        public static final int PHONE             = 0x0200;
        public static final int NETWORKING        = 0x0300;
        public static final int AUDIO_VIDEO       = 0x0400;
        public static final int PERIPHERAL        = 0x0500;
        public static final int IMAGING           = 0x0600;
        public static final int WEARABLE          = 0x0700;
        public static final int TOY               = 0x0800;
        public static final int HEALTH            = 0x0900;
        public static final int UNCATEGORIZED     = 0x1F00;
    }
