### Central mode: central model

> The app acts as a central device and connects to other BLE4.0 peripherals.

```css
//导入.h文件和系统蓝牙库的头文件
#import "BabyBluetooth.h"
//定义变量
BabyBluetooth *baby;

-(void)viewDidLoad {
    [super viewDidLoad];

    //初始化BabyBluetooth 蓝牙库
    baby = [BabyBluetooth shareBabyBluetooth];
    //设置蓝牙委托
    [self babyDelegate];
    //设置委托后直接可以使用，无需等待CBCentralManagerStatePoweredOn状态
    baby.scanForPeripherals().begin();
}

//设置蓝牙委托
-(void)babyDelegate{

    //设置扫描到设备的委托
    [baby setBlockOnDiscoverToPeripherals:^(CBCentralManager *central, CBPeripheral *peripheral, NSDictionary *advertisementData, NSNumber *RSSI) {
        NSLog(@"搜索到了设备:%@",peripheral.name);
    }];

    //过滤器
    //设置查找设备的过滤器
    [baby setFilterOnDiscoverPeripherals:^BOOL(NSString *peripheralName) {
    //设置查找规则是名称大于1 ， the search rule is peripheral.name length > 1
    if (peripheralName.length >1) {
        return YES;
    }
        return NO;
    }];

//.......
}
```

```css
//导入.h文件和系统蓝牙库的头文件
#import "BabyBluetooth.h"
//定义变量
BabyBluetooth *baby;

-(void)viewDidLoad {
    [super viewDidLoad];

    //配置第一个服务s1
    CBMutableService *s1 = makeCBService(@"FFF0");
    //配置s1的3个characteristic
    makeCharacteristicToService(s1, @"FFF1", @"r", @"hello1");//读
    makeCharacteristicToService(s1, @"FFF2", @"w", @"hello2");//写
    makeCharacteristicToService(s1, genUUID(), @"rw", @"hello3");//可读写,uuid自动生成
    makeCharacteristicToService(s1, @"FFF4", nil, @"hello4");//默认读写字段
    makeCharacteristicToService(s1, @"FFF5", @"n", @"hello5");//notify字段
    //配置第一个服务s2
    CBMutableService *s2 = makeCBService(@"FFE0");
    makeStaticCharacteristicToService(s2, genUUID(), @"hello6", [@"a" dataUsingEncoding:NSUTF8StringEncoding]);//一个含初值的字段，该字段权限只能是只读

    //实例化baby
    baby = [BabyBluetooth shareBabyBluetooth];
    //配置委托
    [self babyDelegate];
    //启动外设
    baby.bePeripheral().addServices(@[s1,s2]).startAdvertising();
}

//设置蓝牙外设模式的委托
-(void)babyDelegate{

    //设置添加service委托 | set didAddService block
    [baby peripheralModelBlockOnPeripheralManagerDidUpdateState:^(CBPeripheralManager *peripheral) {
    NSLog(@"PeripheralManager trun status code: %ld",(long)peripheral.state);
    }];

    //设置添加service委托 | set didAddService block
    [baby peripheralModelBlockOnDidStartAdvertising:^(CBPeripheralManager *peripheral, NSError *error) {
    NSLog(@"didStartAdvertising !!!");
    }];

    //设置添加service委托 | set didAddService block
    [baby peripheralModelBlockOnDidAddService:^(CBPeripheralManager *peripheral, CBService *service, NSError *error) {
    NSLog(@"Did Add Service uuid: %@ ",service.UUID);
    }];

//.....
}
```

### Peripheral mode: peripheral model

> The app simulates a BLE4.0 peripheral that other devices can connect to and use.  
>  Simulate a peripheral with 2 services and 6 characteristics.
