ios中蓝牙自动连接出现硬件提示框的问题

 

出现如图所示情况，这时候有两种方法可以处理，一种是让硬件部修改硬件配对，另一种是程序里面测试该提示框的对应特征值，不要调用该特征值就不会出现

//2.扫描到Characteristics,特征回调

-(void)peripheral:(CBPeripheral *)peripheral didDiscoverCharacteristicsForService:(CBService *)service error:(NSError *)error{

    

    for (CBCharacteristic *characteristic in service.characteristics)

    {

        _writePeripheral = peripheral;

      

        //截取设备uuid6

        NSString *UID2 =[UUIDSERVICE2 substringWithRange:NSMakeRange(4, 4)];

        //转化为大写

        NSString*UUIDString2 =[UID2 uppercaseString];

        

        //获取当前密码状态

        if ( [characteristic.UUID.UUIDString isEqualToString:UUIDString2]) {

            _readCharacteristic =characteristic;

            

            [peripheral setNotifyValue:YES forCharacteristic:characteristic];

            

        }

 

        

        //截取设备uuid6

        NSString *UID6 =[UUIDSERVICE6 substringWithRange:NSMakeRange(4, 4)];

        //转化为大写

        NSString*UUIDString6 =[UID6 uppercaseString];

        

        //截取设备uuid4

        NSString *UID4 =[UUIDSERVICE4 substringWithRange:NSMakeRange(4, 4)];

        //转化为大写

        NSString*UUIDString4 =[UID4 uppercaseString];

      //写入数据

        if ( [characteristic.UUID.UUIDString isEqualToString:UUIDString6]) {

            // 拿到特征,和外围设备进行交互   保存写的特征

            _writeDataCharacteristic = characteristic;

 

            [peripheral setNotifyValue:YES forCharacteristic:characteristic];

        }

        //获取当前状态

        if ( [characteristic.UUID.UUIDString isEqualToString:UUIDString4]) {

            _readCharacteristic =characteristic;

            

            [peripheral setNotifyValue:YES forCharacteristic:characteristic];

            

        }

        

 

        

        

    }

}

 

在这里不要调用多余的特征值和提示框显示的特征值，

   [peripheral readValueForCharacteristic:characteristic];这行代码要注意在特定的特征值里再调用，特征值外面别调用，不然问题就来了
