Question

我有一个带有广播接收器的Android应用程序，等待与蓝牙OBD设备的连接。

一旦建立连接，这就是我的BroadcastReceiver

中的示例代码

    if (action.equals(BluetoothDevice.ACTION_ACL_CONNECTED)) {
        BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
        if (/*need this part: condition to check if device is obd */) {
            //do something
        }
    }

我需要的是如何检查设备是否为obd。

提前致谢！

似乎没有api级别的直接解决方案。 OBD设备属于UNCATEGORIZED类别。

您可以使用以下方法获取设备类型：

private String getBluetoothClass(BluetoothDevice device) {

    String bluetoothClassName = "";
    int bluetoothClass = device.getBluetoothClass()
            .getDeviceClass();
    switch (bluetoothClass) {

    case Device.AUDIO_VIDEO_CAMCORDER:
        bluetoothClassName = "AUDIO_VIDEO_CAMCORDER";
        break;
    case Device.AUDIO_VIDEO_CAR_AUDIO:
        bluetoothClassName = "AUDIO_VIDEO_CAR_AUDIO";
        break;

        bluetoothClassName = "AUDIO_VIDEO_HANDSFREE";

        bluetoothClassName = "AUDIO_VIDEO_LOUDSPEAKER";
        break;
    case  Device.AUDIO_VIDEO_MICROPHONE:
        bluetoothClassName = "AUDIO_VIDEO_MICROPHONE";
        break;
    case Device.AUDIO_VIDEO_PORTABLE_AUDIO:
        bluetoothClassName = "AUDIO_VIDEO_PORTABLE_AUDIO";

    case Device.TOY_GAME:
        bluetoothClassName = "TOY_GAME";
        break;
    case Device.TOY_ROBOT:
        bluetoothClassName = "TOY_ROBOT";

        break;
    default:
        bluetoothClassName = "" + bluetoothClass;
    }

    return bluetoothClassName;
}

您可以将UNCATEGORIZED类型用作主要＆＃39;过滤器＆＃39;对于OBD设备:) :)但是为了确认它是一个OBD设备，解决方案是发送一个有效的OBD命令，如ECHO Command（ate0）并检查响应。

如何知道连接的设备是否是OBD？
