IOBluetoothDevice connectionComplete protocol
by Paul Davis 28 Dec '02

Please ignore my previous question. I didn't understand the (id)target argument properly but now I do. The connectionComplete protocol works fine.

IOBluetoothDevice connectionComplete protocol
by Paul Davis 27 Dec '02

27 Dec '02

Is there a problem with the connectionComplete protocol associated with IOBluetoothDevice class? When I try to use the openConnection method with the target specified this callback method never gets called. The openConnection actually works, however.

Re: ObexSample

Thanks, this works. But now another thing happens :-) The application now doesn't crash anymore, but I can't get a connection :-( Two things happen: 1. Connecting with the device address in the Textfield: -> the phone indicates a connection on its display, but OBEXSample says: Opening connection... OBEXConnect Error occurred: -21876 I changed the output to int because in obex.h they are defined as negative values as well. This is the error: kOBEXSessionNotConnectedError, Session does not have an open connection. Which is in my opinion correct, because WE WANT TO CREATE A CONNECTION :-) The phone indicates a connection until I quit opexsample. 2. Connecting with the browser: I testet it with the serial port and one of the obex ports. Which one is the correct one or doesn't that matter because we only want to get the dev address? Ok, here is what happens: I search my phone, select a service and press OK. From then on, my phone indicates a BT connection on its display. But ObexSample displays absolutely nothing. No error, no connection, nothing. I think it waits for the CommandSent Handler to get called, but this one is never called (there is an NSLog in it, but the console reports nothing). When I now press the connect button again, I get an OBEX DISCONNECT ERROR with the same error value as above. So somehow a connection is established in both cases, but the IOBTFramework doesn't recognize it or so. When does the phone display a connection? Maybe the connection I get is no OBEX connection but a lower level connection ? Any ideas ? Maybe it is the phones fault? it is a SIEMENS S 55, ever tried an obex connection with that phone? Thanks for any help! Best regards! Merry Christmas and Happy Holidays! :-) Tobi Hermann ps: Another small question: When I plug in the Bluetooth Adapter (USB), the machine gets really slow! And the cpu cooler doesn't stop anymore. Does it eat so much cpu time? The problem is: When I unplug it again, these effects don't stop. Can I somehow kill the BT stuff? It seems that it doesn"t stop itself when unplugging the USB Device. Just killing BLUED doesnt work. It immediately gets restarted again. I have to restart my powerbook to get it faster and cooler again :) The BT Device is from ACER.

Tobi, Try adding an (extra) retain on the OBEXSession object used in the code. We've had some changes to the retain/release mechanisms, so most likely something that was 'getting lucky' with the previous compiler is now being exposed. If that doesn't work, let me know and I'll take a closer look. Also, if you can enable crash logs in the Console.app and send it to me, it'll help determine what is going on.

ObexSample
by Tobias Hermann 21 Dec '02

21 Dec '02

hi! I am trying to get ObexSample to work but i don't succeed. I just downloaded the Dec02 Dev Tools. I can compile and run obex sample and discover my phone ( a simens s55 ), but that is all. Which service do I have to select in the device dialog? When I select e.g. OBEX something or Serial Port and press ok, nothing happens (even the device address isn"t filled in the TextField or is that intended?). When I press Connect then, the device displays a connection and Obex Sample crashes. On the other hand when I try to input the device address directly, the same problem appears: The phone itself displays a connection but then obexsample crashes. Has somebody an idea? thanx!

User Interface Lockup
by Crichlow, Eric 20 Dec '02

20 Dec '02

I'm not even sure bluetooth really has anything to do with this problem, but it occurs in my bluetooth event callback, so that's where I'm focussing my attention. I'm using a bluetooth tablet (or whiteboard) to control the Mac by mapping the points generted by the tablet to pixels on the screen and generating mouse events (using CGPostMouseEvent) on the relative screen coordinates. Essentially, the tablet becomes a mouse. The application that controls processing the bluetooth events and generating the mouse events also has a user interface window built with Interface Builder. On this window are several buttons and 2 NSTableViews. If, in the bluetooth event callback, I generate a mouse event that clicks on one of the buttons (which has a connection to a target method in the code) or a populated row in the table (the NSTableView does not have a connection set), OS X's user interface locks up. What I mean by "locks up" is that I can move the mouse (with the actual mouse... bluetooth events are no longer processed) but anything I click on gives me no response. Alt-Apple-Esc does nothing. However, it's just the user interface, not the OS itself, that is frozen. Other applications continue to update their windows (though I can't select them), iTunes continues to play music, and I can log into the system from another Mac. I set a breakpoint on the first line of code in the action method for the button. I never make it to that breakpoint. So my belief is that the lockup comes after I fire off the mouse event but before the action method gets called. Could this be caused by doing too much (initiating a mouse event) within the bluetooth event callback? ...Thanx... ...Eric Crichlow... ...GTCO CalComp... _______________________________________________ bluetooth-dev mailing list | bluetooth-dev(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/bluetooth-dev Do not post admin requests to the list.

Another request for public API for Bluetooth Inquiry
by Crichlow, Eric 17 Dec '02

17 Dec '02

I realize it's been about a month since this issue was last discussed, but the comment was made that knowing what users need affects the priority of API development up at Apple. I too, feel that I "need" the ability to do inquiries without using Apple's browser. The application I'm developing manages multiple connections to both USB and bluetooth devices. The devices are (usually one) interactive whiteboard and (usually multiple) tablets. My app is a Mac version of a pre-existing Windows app. The powers that be prefer the Mac version's interface to work as much like the Windows version as possible, and the Windows version manages all of the devices in it's own single, custom window. The fact that on the Mac I have to bring up Apple's panel to connect a device instead of managing all of the devices on my own window has not gone over very well. And it's not just the Windows look and feel compatibility. I'm a Mac guy and even I don't like the way it looks/works from a Mac-centric perspective. Yes, I can accomplish what needs to be accomplished with the current functionality, but I feel my app would look and work a bit better if I could do the inquiry myself, without the panel, and manage the results myself.

CSR include file
by Jose Velez 09 Dec '02

Hi all, I'm trying to connect a BT module with CSR chipset (USB interface). I got the csrbc01.sys driver from the CSR site, but I cannot find the corresponding include file (I guess it's only provided with the SDK). I would be grateful if someone can send me the csrbc01.h.
