It is an open source software suite for S60 mobile phones, which is written in Python. Its GUI is based on PyQt4 [2] and it uses Bluetooth to connect to a mobile phone. I tried to port this application to Mac OS X using lightblue as bluetooth wrapper for IOBluetooth. I tried to handle the bluetooth connection in a seperate thread (like in Linux and Windows) [3], but this seems to be not possible with IOBluetooth. My next try was to use an asynchronous connection instead and use IOBluetooth directly. It works great with the attached Objective-C application [4]. But how can I use this wrapper in my Python application? When I import this extension using objc I already have the Qt event loop running. But I also have to start the Cocoa event loop (CFRunLoopRun()) if I want to receive rfcommChannelData and rfcommChannelOpenComplete events? Is it possible to integrate this event loop in Qt, like it is possible to integrate the Qt event loop in GTK+? Did anybody try something like this? Are there any examples? Thank you for every help, Lukas Hetzenecker [1] http://series60-remote.sorceforge.net [2] http://www.riverbankcomputing.co.uk/software/pyqt/intro [3] thread.py (attachment) [4] async.m (attachment) from PyQt4.QtCore import * from PyQt4.QtGui import * import lightblue import threading import Foundation #class Thread(QThread): #or: class Thread(threading.Thread): def run(self): pool = Foundation.NSAutoreleasePool.alloc().init() sock = lightblue.socket() print "connecting" sock.connect(('00:1B:AF:84:FF:E2', 18)) print "connected" print "received", sock.recv(1024) print "finish..." class Button(QPushButton): def __init__(self): QPushButton.__init__(self, "Start thread") self.connect(self, SIGNAL("clicked()"), self.start) def start(self): self.thread = Thread() self.thread.start() app = QApplication([]) button = Button() button.show() app.exec_() #import <Foundation/NSObject.h> #import <IOBluetooth/objc/IOBluetoothDevice.h> #import <IOBluetooth/objc/IOBluetoothDeviceInquiry.h> #import <IOBluetooth/objc/IOBluetoothRFCOMMChannel.h> #import <stdio.h> @interface ConnectionHandler : NSObject {} - (void)rfcommChannelOpenComplete:(IOBluetoothRFCOMMChannel*)channel status:(IOReturn)status; - (void)rfcommChannelData:(IOBluetoothRFCOMMChannel*)channel data:(void *)dataPointer length:(size_t)dataLength; @end @implementation ConnectionHandler - (void)rfcommChannelOpenComplete:(IOBluetoothRFCOMMChannel*)channel status:(IOReturn)status { if( kIOReturnSuccess == status ) { printf("connection established\n"); [channel writeSync: "110\x02\n" length: 5]; } else { printf("Connection error!\n"); CFRunLoopStop( CFRunLoopGetCurrent() ); } } - (void)rfcommChannelData:(IOBluetoothRFCOMMChannel*)channel data:(void *)dataPointer length:(size_t)dataLength { printf("received: %s\n", dataPointer); [channel writeSync: "110\x02\n" length: 5]; CFRunLoopStop( CFRunLoopGetCurrent() ); } @end int main( int argc, const char *argv[] ) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSString *addr_str = @"00:1B:AF:84:FF:E2"; BluetoothDeviceAddress addr; IOBluetoothNSStringToDeviceAddress( addr_str, &addr ); IOBluetoothDevice *remote_device = [IOBluetoothDevice withAddress:&addr]; IOBluetoothRFCOMMChannel *chan; ConnectionHandler *handler = [[ConnectionHandler alloc] init]; [remote_device openRFCOMMChannelAsync:&chan withChannelID:18 delegate: handler]; CFRunLoopRun(); printf("exited!"); [handler release]; [pool release]; return 0; } _______________________________________________ Do not post admin requests to the list.

When I use a D-Link usb bluetooth adapter, the same sequence takes only 15ms. I get similar fast times using the native bluetooth hardware of MacBooks and MacBook Pros. The iMac is the only machine we have problems with. Any ideas why? Need more info? Thanks _______________________________________________ Do not post admin requests to the list. They will be ignored.
