#if UNITY_ANDROID
    private static AndroidJavaClass _helper;
    public static AndroidJavaClass helper
    {
        get
        {
            if (_helper != null) return _helper;

            return _helper;
        }
    }

發送數據給Unity，receiver = "BLHelper", method = "onMsg"

    /**
     * 發送數據到Unity
     *
     * @param fmt 格式化數據
     */
    private static void sendToApp(String fmt) {
        Log.d(TAG, "sendToApp: " + fmt);
        UnityPlayer.UnitySendMessage(receiver, method, fmt);
    }

掃描設備實例

    JSONObject obj = new JSONObject();
    try {
        obj.put("type", TYPE.FIND_DEVICE.ordinal());
        obj.put("name", device.getName());
        obj.put("address", device.getAddress());
        obj.put("state", btManager.getConnectionState(device, BluetoothProfile.GATT)); //0=disconnected 1=connecting 2=connected 3=disconnecting
        sendToApp(obj.toString());
    } catch (JSONException e) {
        e.printStackTrace();
    }

SDK方法説明

1. init(String param) 初始化數據和請求藍牙權限
2. scanDevice 掃描設備
3. scanStop 停止掃描
4. connectDevice(String address) 連接設備
5. disconnectDevice(String address) 斷開連接
6. getVersion(String address) 獲取設備固件版本
7. getBattery(String address) 獲取設備電量

Unity接收方法數據方法

    enum TYPE {
        none = 0,
        data = 1,//藍牙數據
        find_device = 2,//掃描設備回調
        connect_succeed = 3,//連接成功回調
        connect_failed = 4,//連接失敗回調
        disconnected = 5,//斷開連接回調
        device = 6 //獲取設備信息（電量，固件版本）
    };
