iOS蓝牙连接多台设备

1. 框架
利用蓝牙CoreBluetooth框架 在7.0以上就用这个连接蓝牙框架。

2.连接
连接多台蓝牙设备与单台连接蓝牙设备的道理是一样，同样需要首先发现蓝牙设备然后把发现的设备添加到一个 NSMutableArray 保存起来。

具体看下面代码：

首先 我们需要创建

@property (nonatomic,strong ) CBCentralManager *manager;// 中心设备@property (nonatomic,strong ) NSMutableArray   <CBPeripheral*>*devices;// 扫描到的外围设备@property (nonatomic, strong) NSMutableArray   *connectSuccess;//连接成功的的外设

上面 CBCentralManager 是指定的中心设备（手机 ，平板…)

而 CBPeripheral 所指的是需要连接的蓝牙设备（耳机,手表，手环…等等）

需要一个 connectSuccess 用来保存连接成功的设备。

设置 CBCentralManager 代理

@interface ViewController ()<CBCentralManagerDelegate>

当打开程序的时候就要实现此代理 CBCentralManagerDelegate

并自动检查手机蓝牙是否打开，只有打开的时候才会去自动的扫描蓝牙设备

//中心设备状态改变的代理必须实现- (void)centralManagerDidUpdateState:(CBCentralManager *)central{    switch (central.state)    {        case CBManagerStatePoweredOn:            NSLog(@"蓝牙已打开");            //自动开始扫描            [self startScan];            break;        case CBManagerStateUnknown:            break;        case CBManagerStatePoweredOff:            NSLog(@"蓝牙未打开");            break;        case CBManagerStateResetting:            //            [self showInfo:@"蓝牙初始化中"];            break;        case CBManagerStateUnsupported:            NSLog(@"蓝牙不支持状态");            //            [self showInfo:@"蓝牙不支持状态"];            break;        case CBManagerStateUnauthorized:            //            [self showInfo:@"蓝牙设备未授权"];            break;        default:            break;    }}

扫描蓝牙

下面的代码 扫描不是一直在进行 15秒后结束扫描

/* * 开始扫描 */-(void) startScan{    NSLog(@"scan....");    [self.manager scanForPeripheralsWithServices:nil options:nil];    //15秒后停止。    //(开启扫描后会不停的扫描)    [self performSelector:@selector(stopScan) withObject:nil afterDelay:15];}

停止扫描

中心设备停止（手机、平板…）

/** *  停止扫描 */-(void)stopScan{    [self.manager stopScan];    NSLog(@"stopScan....");}

扫描到设备就要添加设备 最好是放到tableview中

并所有扫描出来的 peripheral 添加到 self.devices 中

相应的tableview也要刷新一下

/** *  扫描蓝牙的代理 * *  @param central           中心设备 *  @param peripheral        扫描到的蓝牙 *  @param advertisementData 在ios中蓝牙广播信息中通常会包含以下4种类型的信息。ios的蓝牙通信协议中不接受其他类型的广播信息。 因此需要注意的是，如果需要在扫描设备时，通过蓝牙设备的Mac地址来唯一辨别设备，那么需要与蓝牙设备的硬件工程师沟通好：将所需要的Mac地址放到一下几种类型的广播信息中。 通常放到kCBAdvDataManufacturerData这个字段中。 kCBAdvDataIsConnectable = 1; kCBAdvDataLocalName = XXXXXX; kCBAdvDataManufacturerData = <XXXXXXXX>; kCBAdvDataTxPowerLevel = 0; *  @param RSSI              信号强度 *///扫描到的蓝牙设备添加到devices数组中，刷新列表-(void)centralManager:(CBCentralManager *)centraldidDiscoverPeripheral:(CBPeripheral *)peripheral    advertisementData:(NSDictionary<NSString *,id> *)advertisementData                 RSSI:(NSNumber *)RSSI{    if (![self.devices containsObject:peripheral]) {        [self.devices addObject:peripheral];        [self.tableView reloadData];        NSLog(@"发现外围设备:%@---RSSI:%@---advertisementData:%@",peripheral,RSSI,advertisementData);    }}

点击tableview中各个蓝牙选择项 并连接蓝牙 提示给用户 连接成功

并把连接成功的 peripheral 添加到 self.connectSuccess中

/** *  蓝牙连接成功时候的代理 * *  @param central    中心设备 *  @param peripheral 当前连接的设备 */-(void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral{    NSLog(@"%@名字的蓝牙连接成功",peripheral.name);    _maincell.txtDeviceContent.text = @"已连接";    //cell.detailTextLabel.text = @"已连接";    [self.connectSuccess addObject:peripheral];}

同样也有失败和断开的时候

失败的时候不做处理 也可以做处理
但是断开的时候 需要把 连接成功的 self.connectSuccess 设备移除掉
并在tableview中把 连接成功的文字清空。这样就变为没有连接的状态

/** *  蓝牙链接失败的代理 * *  @param central    中心设备 *  @param peripheral 当前连接的外设 *  @param error      错误信息 */- (void)centralManager:(CBCentralManager *)central didFailToConnectPeripheral:(CBPeripheral *)peripheral error:(nullable NSError *)error;{    NSLog(@"%@名字的蓝牙连接失败",peripheral.name);}/** *  蓝牙断开连接的代理 * *  @param central    中心设备 *  @param peripheral 当前需要断开连接的外设 *  @param error      错误信息 */-(void)centralManager:(CBCentralManager *)central didDisconnectPeripheral:(CBPeripheral *)peripheral error:(NSError *)error{    NSLog(@"%@名字的蓝牙断开链接",peripheral.name);    _maincell.txtDeviceContent.text = @"";    for(int i=0;i<_connectSuccess.count;i++){        CBPeripheral *p = [_connectSuccess objectAtIndex:i];        if ([p.identifier.UUIDString isEqualToString:peripheral.identifier.UUIDString]) {            [self.connectSuccess removeObject:p];        }    }}

具体的连接的代码如下：

3.数据读取
这里的数据读取是分开来写的 如果是同样的设备 并底层给的UUID 接收和发送数据是同样的话可以写一个就可以并可以用tabview 中的cell来写
但是如果需要连接不相同的UUID的时候 并解析格式不一样介意使用多个

我创建的是view 可以使用MVC 来实现 创建NSObject也可以 毕竟是 数据获取

用不上view

如 OneView.h

#import <UIKit/UIKit.h>#import <CoreBluetooth/CoreBluetooth.h>@interface OneView : UIView<CBPeripheralDelegate>@property (nonatomic, strong) UITextView *textView;@property (nonatomic, strong) CBCharacteristic *oneNotiC, *oneWriteC;@property (nonatomic, strong) NSMutableString *mutStr;@end

OneView.m 如下

在这个里面 我们连接到设备之后 需要读取 peripheral 里面的UUID 包含了服务和特征的 UUID

首先读取服务的 一样的要实现 CBPeripheralDelegate 代理

#pragma mark - 外围设备服务的代理- (void)peripheral:(CBPeripheral *)peripheral didDiscoverServices:(NSError *)error{    //NSLog(@"123");    for (CBService *s in peripheral.services) {        NSLog(@"%@",[s.UUID UUIDString]);        [peripheral discoverCharacteristics:nil forService:s];    }}

当发现了服务UUID之后 我们需要 服务里面的具体携带的特征UUID 也是数据解析的 UUID

这里面有些是多余的你可以选择你自己需要的

#pragma mark 2. 外围设备 扫描到服务下有哪些特征- (void)peripheral:(CBPeripheral *)peripheral didDiscoverCharacteristicsForService:(nonnull CBService *)service error:(nullable NSError *)error{    if (error){        NSLog(@"扫描特征出现错误,错误原因:%@",error);    }else{        //拿到服务中所有的特征        NSArray *characteristics = service.characteristics;        //遍历特征,拿到需要的特征进行处理        for (CBCharacteristic *characteristic in characteristics){            NSLog(@"所有的特征为:%@",characteristic.UUID.UUIDString);            //如果是温度数据处理            if([characteristic.UUID.UUIDString isEqualToString:@"底层给你的UUID"]){                //将全部的特征信息打印出来                //_peripheral = peripheral;                [peripheral setNotifyValue:YES forCharacteristic:characteristic];                NSLog(@"%@",characteristic);            }            //这里是发送 设备设置蓝牙发送温度数据的值            else if([characteristic.UUID.UUIDString isEqualToString:@"底层给你的UUID"]){                [peripheral setNotifyValue:YES forCharacteristic:characteristic];                NSLog(@"写入的值为:%@",characteristic);            }            //如果是ota进行ota升级            else if([characteristic.UUID.UUIDString isEqualToString:@"底层给你的UUID"]){                //_peripheral = peripheral;                //设置通知                [peripheral setNotifyValue:YES forCharacteristic:characteristic];                NSString *s = @"OTA";                NSDictionary *tempOta = [NSDictionary dictionaryWithObject:s forKey:@"ota"];                [[NSNotificationCenter defaultCenter] postNotificationName:@"tempOTA" object:nil userInfo:tempOta];            }            //无键按钮DFU            else if([characteristic.UUID.UUIDString isEqualToString:@"底层给你的UUID"]){                [peripheral setNotifyValue:YES forCharacteristic:characteristic];                NSLog(@"写入的OTA值为:%@",characteristic);            }        }    }}

当读取到你需要的UUID的时候直接读取数据
在这里面你 可以用你们底层给你们的算法去解析数据

我写的不代表你的

#pragma mark 3.接收外围设备的数据（这里就能接到蓝牙发送过来的数据，具体协议就要看你们是怎么定义的）-(void)peripheral:(CBPeripheral *)peripheral didUpdateValueForCharacteristic:(CBCharacteristic *)characteristic error:(NSError *)error{    NSString *temps=[self getTempData:characteristic];    //self.textView.text = temps;    //发送广播来更新通知信息    //第一个的温度数据    NSString *blename = peripheral.name;    NSString *c = [NSString stringWithFormat:@"%@",peripheral.identifier];    NSString *b = NULL;    if ([[UIDevice currentDevice].systemVersion floatValue] < 10.0) {        b = [c substringFromIndex:30];    }else{        b = [c substringFromIndex:30];    }    NSString *bleaddre = b;    NSString *tempss = [temps stringByAppendingString:@","];    NSString *tempsss = [blename stringByAppendingString:@","];    NSString *tempssss = [tempsss stringByAppendingString:bleaddre];    NSString *tempsssss = [tempss stringByAppendingString:tempssss];    NSDictionary *tempDict = [NSDictionary dictionaryWithObject:tempsssss forKey:@"tempOne"];    [[NSNotificationCenter defaultCenter] postNotificationName:@"tempNofictionOne" object:nil userInfo:tempDict];}

还需要打开通知 我这个项目是通过接收通知来更新温度数据的

//设置通知-(void)notifyCharacteristic:(CBPeripheral *)peripheral             characteristic:(CBCharacteristic *)characteristic{    //设置通知，数据通知会进入：didUpdateValueForCharacteristic方法    [peripheral setNotifyValue:YES forCharacteristic:characteristic];    //[_centerManager stopScan];}
