在X code。创建一个基于终端的蓝牙监视器？ [英] Create a Terminal-Based Bluetooth Monitor in XCode?

问题描述

我想创建一个连接到蓝牙设备，输出由蓝牙设备发出的任何命令终端应用程序。到目前为止，我能够扫描并输出可用设备的列表。

任何方向将大大AP preciated - 这甚至可能？我应该怎么看呢？我试图用BluetoothDeviceAddress和IOBluetoothL2CAPChannelGetDevice但没有成功呢。

下面是我的code迄今：

 的#include＆LT;基金会/ Foundation.h＆GT;
＃包括LT与可可/ Cocoa.h＆GT;
＃包括LT＆; IOBluetooth / objc / IOBluetoothDeviceInquiry.h＆GT;
＃包括LT＆; IOBluetoothUI / IOBluetoothUI.h＆GT;INT主（INT ARGC，为const char * argv的[]）{
    NSAutoreleasePool *池= [[NSAutoreleasePool的alloc]初始化];
    的NSLog（@开始搜索蓝牙）;    IOBluetoothDeviceInquiry * D = [[IOBluetoothDeviceInquiry新] INIT]
        并[d setInquiryLength：5];
        并〔d setUpdateNewDeviceNames：TRUE];
        研究[D开始]。    [NSThread sleepUntilDate：[的NSDate dateWithTimeIntervalSinceNow：7];
        [D停止]
        NSArray的* DEVICELIST = [ÐfoundDevices]    的NSLog（@发现％d个设备，[DEVICELIST计数]）;    的for（int i = 0; I＆LT; D​​EVICELIST计数];我++）{        NSScanner * theScanner = [NSScanner scannerWithString：[的NSString stringWithFormat：@％@，[DEVICELIST objectAtIndex：i]]];
        * NSString的tagDeviceName = @MNAME  - ;
        * NSString的tagEndLine = @\\ n;        * NSString的currentDeviceName;        //从目前的数组值提取MNAME
        而（[theScanner isAtEnd] == NO）{
            [theScanner scanUpToString：tagDeviceName intoString：NULL];
            [theScanner scanString：tagDeviceName intoString：NULL];
            [theScanner scanUpToString：tagEndLine intoString：放大器; currentDeviceName]。
        } //结束[theScanner isAtEnd]        的NSLog（@设备名称：％@，currentDeviceName）;    }
    [池释放];
    返回0;
}
 

解决方案

接下来的步骤将是：
1.发现通过SDP设备上可用的服务
2.连接到服务并读取数据。

有关数据发送/接收您可以使用SPP配置文件 - 假设你正在连接的设备正在使用此配置文件发送的数据

I want to create a Terminal application that connects to a Bluetooth Device and outputs any commands that are sent out by the bluetooth device. So far, I am able to scan and output a list of available devices.

Any direction would be greatly appreciated - is this even possible? What should I be looking at now? I tried to use BluetoothDeviceAddress and IOBluetoothL2CAPChannelGetDevice but haven't had any success yet.

Here is my code so far:

#include <Foundation/Foundation.h>
#include <Cocoa/Cocoa.h>
#include <IOBluetooth/objc/IOBluetoothDeviceInquiry.h> 
#include <IOBluetoothUI/IOBluetoothUI.h>

int main (int argc, const char * argv[]) { 
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
    NSLog(@"start bluetooth search"); 

    IOBluetoothDeviceInquiry *d = [[IOBluetoothDeviceInquiry new] init]; 
        [d setInquiryLength: 5]; 
        [d setUpdateNewDeviceNames: TRUE]; 
        [d start];

    [NSThread sleepUntilDate: [NSDate dateWithTimeIntervalSinceNow: 7]]; 
        [d stop]; 
        NSArray *deviceList = [d foundDevices]; 

    NSLog(@"found %d devices", [deviceList count]); 

    for(int i=0;i < [deviceList count]; i++) {

        NSScanner *theScanner = [NSScanner scannerWithString:[NSString stringWithFormat:@"%@", [deviceList objectAtIndex:i]]];


        NSString *tagDeviceName = @"mName - ";
        NSString *tagEndLine = @"\n";       

        NSString *currentDeviceName;

        // extract the mName from the current array value
        while ([theScanner isAtEnd] == NO) {
            [theScanner scanUpToString:tagDeviceName intoString:NULL];
            [theScanner scanString:tagDeviceName intoString:NULL];
            [theScanner scanUpToString:tagEndLine intoString:&currentDeviceName];           
        } // end [theScanner isAtEnd]

        NSLog(@"device name: %@", currentDeviceName);

    }


    [pool release]; 
    return 0; 
}

解决方案

The next step will be : 1. Discover the services available on the device via SDP 2. Connect to the service and read the data.

You can use the SPP profile for data send / receive - assuming that the device you are connecting to is using this profile to send the data.
