我可以把ANCS做到keyfob里吗？

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。

两个task的init函数如下：

void TimeApp_Init( uint8 task_id )

{

timeAppTaskId = task_id;

// Register to receive incoming ATT Indications/Notifications

GATT_RegisterForInd( timeAppTaskId );

// Setup a delayed profile startup

osal_set_event( timeAppTaskId, START_DEVICE_EVT );

}

oid KeyFobApp_Init( uint8 task_id )

{

keyfobapp_TaskID = task_id;

// until the enabler is set back to TRUE

uint16 gapRole_AdvertOffTime = 0;

uint8 enable_update_request = DEFAULT_ENABLE_UPDATE_REQUEST;

}
