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 *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 = ;
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 *)central
didDiscoverPeripheral:(CBPeripheral *)peripheral
advertisementData:(NSDictionary *)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];
}
}
}

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 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];
}
