iOS蓝牙：中心 - 外围设备在接受配对请求之前已连接

Question

我在蓝牙连接方面遇到了一些问题，因为我正在将一台设备与其他CBCentral和CBPeripherel概念进行通信。 但是，Peripherel设备在接受配对请求弹出之前连接到Central，基本上是在接受配对请求之前将一些数据传递给外设。

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

{

for (CBCharacteristic *characteristic in service.characteristics)
{

    NSLog(@"for loop for charactersitc %@",characteristic.UUID);
    // And check if it's the right one
    if ([characteristic.UUID isEqual:[CBUUID UUIDWithString:TRANSFER_SLIDEINDEX_CHARACTERISTIC_UUID]])
    {
        // If it is, subscribe to it
        [peripheral setNotifyValue:YES forCharacteristic:characteristic];
    }
    if ([characteristic.UUID isEqual:[CBUUID UUIDWithString:TRANSFER_SCROLL_CHARACTERISTIC_UUID]])
    {
        // If it is, subscribe to it
        [peripheral setNotifyValue:YES forCharacteristic:characteristic];
    }

    if ([characteristic.UUID isEqual:[CBUUID UUIDWithString:TRANSFER_FULLSCREEN_CHARACTERISTIC_UUID]])
    {
        // If it is, subscribe to it
        [peripheral setNotifyValue:YES forCharacteristic:characteristic];
    }
    if ([characteristic.UUID isEqual:[CBUUID UUIDWithString:SLIDELENGTH_CHARACTERISTIC_UUID]])
    {
        // WRITE VALUES TO REMOTE
        NSInteger length = self.presentationDataSourceArray.count;
        NSData *chunk = [NSData dataWithBytes: &length length: sizeof(length)];

        [self.discoveredPeripheral writeValue:chunk forCharacteristic:characteristic
                                         type:CBCharacteristicWriteWithResponse];
        [self.discoveredPeripheral setNotifyValue:YES forCharacteristic:characteristic];

    }
    if ([characteristic.UUID isEqual:[CBUUID UUIDWithString:DEVICENAME_CHARACTERISTIC_UUID]])
    {
        NSString *deviceName = [[UIDevice currentDevice]name];
        NSData *chunk = [deviceName dataUsingEncoding:NSUTF8StringEncoding];
        [self.discoveredPeripheral writeValue:chunk forCharacteristic:characteristic
                                         type:CBCharacteristicWriteWithResponse];
        [self.discoveredPeripheral setNotifyValue:YES forCharacteristic:characteristic];

        NSLog(@"Sending Device Name");
    }
    if ([characteristic.UUID isEqual: [CBUUID UUIDWithString:CURRENTSLIDE_CHARACTERISTIC_UUID]])
    {
        self.currentSlideIndexCharacterestics = (CBMutableCharacteristic*) characteristic;
        NSInteger count = self.currentPage;
        NSData *chunk = [NSData dataWithBytes: &count length: sizeof(count)];

        [self.discoveredPeripheral writeValue:chunk forCharacteristic:characteristic
                                         type:CBCharacteristicWriteWithResponse];
        [self.discoveredPeripheral setNotifyValue:YES forCharacteristic:characteristic];
    }


    _isRemoteConnected = YES;
