Question

我叫方法

（void)connectPeripheral:(CBPeripheral *)peripheral options:(nullable NSDictionary<NSString *, id> *)options;

连接我的设备，我的设备在范围内，但我的应用程序仍然无法连接我的设备成功，当我关闭系统BT然后打开BT时，我的应用程序将连接我的设备成功，我不＃39;知道为什么吗？

如果我没有关闭BT然后打开，我可以拨打第一个电话方法

(void)cancelPeripheralConnection:(CBPeripheral *)peripheral;

然后致电

（void)connectPeripheral:(CBPeripheral *)peripheral options:(nullable NSDictionary<NSString *, id> *)options;

它会有意义吗？

要检查天气 您的设备是否已连接 ，您可以使用以下两种委托方法： 目标C：

1）-（void）centralManager：（CBCentralManager *）central didConnectPeripheral：（CBPeripheral *）peripheral

2）-（void）centralManager：（CBCentralManager *）central didDisconnectPeripheral：（CBPeripheral *）peripheral error：（NSError *）error

@property (nonatomic, strong) CBPeripheral *heartRatePeripheral;
#define heartRateServiceCBUUID [CBUUID UUIDWithString:@"0x180D"]

-(void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral 
  *)peripheral
{ 
  [self.Customdelegate HRMoniterStatus:peripheral Status:@"Connected"];
  [_heartRatePeripheral discoverServices:@[heartRateServiceCBUUID]];
}

CustomDelegate：

-(void)HRMoniterStatus:(CBPeripheral *)HRMoniter Status:(NSString 
*)connectionStatus
{
  NSLog(@"HRMoniter connection status ::- %@",connectionStatus);
}

快捷键：

1）func centralManager（_中央：CBCentralManager，didConnect外围设备：CBPeripheral）

2）func centralManager（_ Central：CBCentralManager，didDisconnectPeripheral外设：CBPeripheral，错误：错误？）

let heartRateServiceCBUUID = CBUUID(string: "0x180D")

let heartRatePeripheral : CBPeripheral

func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral)
{
    Customdelegate.hrMoniterStatus(peripheral, status: "Connected")
    heartRatePeripheral.discoverServices([heartRateServiceCBUUID])
}

自定义委托：

func hrMoniterStatus(_ HRMoniter: CBPeripheral?, status connectionStatus: String?) 
{
   print("HRMoniter connection status ::- \(connectionStatus ?? "")")
}
