如何使用iOS上的BluetoothManager.framework私有API发送和接收数据

我设法使用BluetoothManager.framework与demo project BeeTee的指南配对并将设备连接到iPhone

但我不知道如何发送和recv数据,我在类转储标头中找不到API.

似乎答案在于这三个结构：BTAccessoryManagerImpl& BTSessionImpl& BTDeviceImpl,但我无法得到它们的定义.

@class NSMutableDictionary;

struct BTSessionImpl { };
struct BTDeviceImpl { };


@interface BluetoothManager : NSObject {
    struct BTAccessoryManagerImpl { } *_accessoryManager;
    BOOL _audioConnected;
    int _available;
    NSMutableDictionary *_btAddrDict;
    NSMutableDictionary *_btDeviceDict;
    struct BTdiscoveryAgentImpl { } *_discoveryAgent;
    struct BTLocalDeviceImpl { } *_localDevice;
    struct BTPairingAgentImpl { } *_pairingAgent;
    BOOL _scanningEnabled;
    BOOL _scanningInProgress;
    unsigned int _scanningServiceMask;
    struct BTSessionImpl *_session; // struct BTSessionImpl { } *_session;

}

+ (int)lastinitError;
+ (id)sharedInstance;
