objective-cとmacrubyでbluetooth deviceの存在確認をする

objective-c版

main.m

#import <Foundation/Foundation.h>
#import <IOBluetooth/objc/IOBluetoothDevice.h>


int main(int argc, const char * argv[])
{

    NSLog(@"start");
    NSString *addrStr = @"xx:xx:xx:xx:xx:xx"; // bluetooth deviceのMAC Address
        
    IOBluetoothDevice *device = [IOBluetoothDevice deviceWithAddressString:addrStr];

    // タイムアウト3秒
    [device openConnection:nil withPageTimeout:3000 authenticationRequired:false];
        
    if ([device isConnected]) {
            NSLog(@"connected !!!");
    } else {
            NSLog(@"not connected");
    }
        
    [device closeConnection];

    return 0;
}

macruby版

macruby-sample.rb

#! /usr/bin/env macruby

framework 'Foundation'
framework 'IOBluetooth'

device = IOBluetoothDevice.deviceWithAddressString "xx:xx:xx:xx:xx:xx"
device.openConnection(nil, withPageTimeout: 3000, authenticationRequired: false)

if device.isConnected
  puts 'connected!!!'
else
  puts 'not connected.'
end

device.closeConnection
