最近做了几个蓝牙项目,写一下过程,方便大家。
第一步 遵循代理
@interface dbblemanager ()
第二步 设置蓝牙属性
@property (nonatomic ,strong)cbcentralmanager *mycentralmanager;
第三步 实例化
_mycentralmanager = [[cbcentralmanager alloc]initwithdelegate:self queue:nil options:nil];
第四步 实现代理方法
我要评论
- (void)centralmanagerdidupdatestate:(cbcentralmanager *)central
{
if (central.state == cbcentralmanagerstatepoweredon) {
nslog(@"蓝牙已打开");
nsdictionary *options = [nsdictionary dictionarywithobjectsandkeys:[nsnumber numberwithbool:yes], cbcentralmanagerscanoptionallowduplicateskey, nil];
扫描
[_mycentralmanager scanforperipheralswithservices:nil options:options];
}else {
nslog(@"蓝牙已关闭");
nsurl *url=[nsurl urlwithstring:@"prefs:root=bluetooth"];
[[uiapplication sharedapplication]openurl:url];
[dbtipview progresshud:@"设置-蓝牙-打开蓝牙"];
}
}
第五步 代理返回蓝牙外设 连接
- (void)centralmanager:(cbcentralmanager *)central diddiscoverperipheral:(cbperipheral *)peripheral advertisementdata:(nsdictionary *)advertisementdata rssi:(nsnumber *)rssi
{
[_mycentralmanager connectperipheral:peripheral options:nil];
}
第六步
连接上蓝牙
- (void)centralmanager:(cbcentralmanager *)central didconnectperipheral:(cbperipheral *)peripheral
{
[_mycentralmanager stopscan];
}
//连接失败
- (void)centralmanager:(cbcentralmanager *)central didfailtoconnectperipheral:(cbperipheral *)peripheral error:(nullable nserror *)error{
}
//失去连接
-(void)centralmanager:(cbcentralmanager *)central diddisconnectperipheral:(cbperipheral *)peripheral error:(nserror *)error{
}
接下来会开放一个 蓝牙的简单封装。
