TI中文支持网ANCS是从TimeApp的基础上改的，看TimeApp里调用了：
// Initialize GATT Client
VOID GATT_InitClient();
// Register to receive incoming ATT Indications/Notifications
GATT_RegisterForInd( timeAppTaskId );
1. ANCS是不是一定要做client？
2. 那和keyfob会不会冲突？
3. 上面这两个函数的详细功能是什么呢？谢谢！

ouc qzy，
当然可以。
1. 是的。ANCS必须是client。但对于一个设备来说，可以是Client和Server共存。
2. 不会冲突。
3. 这是初始化GATT和注册indication 指定接收的task。

你好，是不是调用GATT_RegisterForInd后会回调对应task中的下面这个回调函数？
// GAP Role Callbacks
static gapRolesCBs_t timeAppPeripheralCB =
{
timeAppGapStateCB, // Profile State Change Callbacks
NULL // When a valid RSSI is read from controller
};
我把ANCS集成到KeyFob里了，添加了两个task，分别是处理KeyFob和Ancs的任务
/* Application */
KeyFobApp_Init( taskID++ );
TimeApp_Init(taskID);
并在初始化的时候通过调用GATT_RegisterForInd注册了ancs的task做为接收task，现在的问题是与手机上的APP连接上（Keyfob里的服务和ANCS都连接上，功能也正常），然后把APP杀掉，但ANCS也不会断开，于是设备端不知道KeyFob里的服务断开了，不能继续广播，于是再打开APP就搜索不到设备了，我要怎么获取KeyFob里的服务是否断开了？断开后我要重新广播。

难道只有设备与手机的连接断开了才会回调到应用层吗？那我这种情况应该怎么处理。。。现在我是用keyfob做防丢器，然后在keyfob里集成了ANCS，防丢器与APP连接后，再把APP杀掉，然后再打开APP却搜索不到设备了，那设备端要怎么才能知道APP被杀掉的动作？只有知道这个动作我才能判断是否要广播。
