Android Bluetooth Low Energy peripheral - Connection loss after bonding

Question

I am implementing Bluetooth Low Energy's HID over GATT (HOGP) profile on Android Lollipop. My target is to use the phone as a keyboard/mouse, which can just plug and play with the default BLE (HID) drivers in Windows 8.1 laptop. The Android phone is supposed to act as BLE peripheral and the laptop should be in BLE central role.

Currently, I am able to establish a very short connection with the laptop. But just right after I enter the passkeys, and bonded successfully with the laptop, the BLE connection will be lost. Have anyone faced this kind of problems before? Or have any solutions on it?

Also, I failed to add generic access service to the gatt server in Android. I am curious if GAP service is included in Android BLE communication by nature? The reason I want to include this service is for defining the "device name", "appearance", and the "peripheral connection parameter update" characteristics. How I can do so?

您的系统是否固定好，我看到类似的东西，在绑定后，我的设备将进入配对列表，然后大约20秒后，蓝牙开/关按钮将自动切换到关闭位置，等待10秒，然后回到原位，我的设备不见了。
