Question

我正在开发一款需要连接到非BLE蓝牙脉搏血氧仪设备才能下载数据的应用。此应用程序不会提交给应用程序商店，所以在这个阶段，我并不担心它被拒绝。

这是我提出的一些基本代码，它基于BeeTee示例，用于连接脉搏血氧仪。

#import "MDBluetoothManager.h"
#import "BTMViewController.h"

@interface BTMViewController () <MDBluetoothObserverProtocol>
{
    IBOutlet UILabel * statusLabel;
}

@property (nonatomic, strong) MDBluetoothDevice * connectedBluetoothDevice;

- (void)receivedBluetoothNotification:(MDBluetoothNotification)bluetoothNotification;

@end

@implementation BTMViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    [[MDBluetoothManager sharedInstance] registerObserver:self];

    if (![[MDBluetoothManager sharedInstance] bluetoothIsPowered])
    {
        //NSLog(@"Bluetooth not powered on!");
        [[MDBluetoothManager sharedInstance] turnBluetoothOn];
    }
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    statusLabel.text = @"Scanning ...";

    [[MDBluetoothManager sharedInstance] startScan];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [[MDBluetoothManager sharedInstance] endScan];

    [self.connectedBluetoothDevice disconnect];

    [super viewWillDisappear:animated];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Bluetooth Connectivity

- (void)receivedBluetoothNotification:(MDBluetoothNotification)bluetoothNotification
{
    BOOL isPowered = [[MDBluetoothManager sharedInstance] bluetoothIsPowered];

    switch (bluetoothNotification)
    {
        case MDBluetoothAvailabilityChangedNotification:
        {
            //NSLog(@"Bluetooth availability changed to %@", [NSNumber numberWithBool:isPowered]);

            if (isPowered)
            {
                [[MDBluetoothManager sharedInstance] startScan];
            }

            break;
        }
        case MDBluetoothPowerChangedNotification:
            //NSLog(@"Bluetooth power changed to %@", [NSNumber numberWithBool:isPowered]);
            break;
        case MDBluetoothDeviceDiscoveredNotification:
        {
            //NSLog(@"Bluetooth device discovered");

            NSArray* detectedBluetoothDevices = [[MDBluetoothManager sharedInstance] discoveredBluetoothDevices];

            for (int index=0; index<detectedBluetoothDevices.count; index++)
            {
                self.connectedBluetoothDevice = [detectedBluetoothDevices objectAtIndex:index];

                //NSLog(@"Bluetooth Device: %@ (%@)", bluetoothDevice.name, bluetoothDevice.address);

                if ([self.connectedBluetoothDevice.name isEqualToString:@"SpO2"])
                {
                    NSLog(@"Pairing with Pulse Oximeter");
                    [statusLabel performSelectorOnMainThread:@selector(setText:) withObject:@"Pairing with Pulse Oximeter" waitUntilDone:NO];
                    self.connectedBluetoothDevice.pin = @"7762";
                    [self.connectedBluetoothDevice connect];
                    [[MDBluetoothManager sharedInstance] endScan];
                }
            }

            break;
        }
        case MDBluetoothDeviceConnectSuccessNotification:
        {
            NSLog(@"Connected to Pulse Oximeter!");
            statusLabel.text = @"Connected to Pulse Oximeter!";
        }
            break;
        case MDBluetoothDeviceRemovedNotification:
            //NSLog(@"Bluetooth device removed");
            break;
        default:
            //NSLog(@"Unknown Bluetooth notification!");
            break;
    }
}

@end

是否有人知道如何启动数据传输以使用私有API下载所有数据？

或

有没有人有另一种方法连接到非BLE设备下载数据？

谢谢

要通过Serial Port Profile传输数据，Apple需要由MFi证书处理的身份验证。我怀疑这可以轻松完成。

但欢迎任何对这个开放主题的贡献！
