Bluetooth Printing
by Gawin Dapper 18 Nov '03

18 Nov '03

Hi All, As a 21 year old student form the Netherlands I'm trying to fix a problem. After buying a HP Deskjet 995C I want to print over a Bluetooth connection. This works fine running Windows XP, but as a Mac user I have to do it with Apple's Panther. http://docs.info.apple.com/article.html?artnum=61743 Since Apple's Bluetooth implementation doesn't support the Bluetooth Printing Profile I wonder if there is ANY way to get this problem fixed. (Without asking Apple for BPP support) Is it posible to develop my own driver or application to fix this? And what is the best way to do this, and where should I start?

Nikita, This problem is device dependent, since a "space available" command is not really in the specification. If a device, such as your phone, is allowing the 60MB transfer to proceed, the phone is at err here - the reason for this is that in the OBEX Put command (a length OBEX header), we send the size of the file it is going to receive. The phone should know better, and refuse the transfer. Therefore, I really don't know of any effective way to test for remote space available.

How to change the Class of Device?
by Tommy Gunnarsson 11 Nov '03

11 Nov '03

Hi. I'm working in a project were a prototype to help persons with special needs is developed. Bluetooth is the central link, where I'm using an iBook with Mac OS X Panther installed. I have build the applications in the Carbon environment in C and I have come to a point where I must Change the Class of Device on the computer. Too bad for me, there is no C: API to do this, (what I can see). I have also searched for a serial driver to establish an serial port to the Bluetooth USB Adapter and send raw HCI Commands. No success here either. The Bluetooth driver AppleUSBBluetoothHCIController seems to have the HCI stack included without the possibility to establish a simple serial port through it. Em I right? My last discovery was the IOBluetoothHCIController.h file in the Kernel framework under the IOKit folder. I believe this is the header file for the Bluetooth Driver, em I right? In this file a method called BluetoothHCIWriteClassOfDevice are located, which could solve my problem. This function is protected which makes it hard to use, I think. My quite big question is: how can I use this function from my Carbon application? Is it possible to make some conversion of this method to my C environment? Or must I make my own Kernel Driver as a Sub Class to the IOBluetoothHCIController Class and make my own conversion? How can I do it? This was many questions, but it is also a really important feature in my application. I hope someone has time and knowledge to give me some guidelines in this issue. Thanks in advice. /Tommy _______________________________________________ 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.

Possible Opportunities
by Hussain Bandukwala 11 Nov '03

11 Nov '03

Dear Friends, As a recent graduate, I am seeking an opportunity to build on the skills and capabilities I have cultivated while in college by applying them in a real-world business environment. My experience with Bluetooth has spurred while working on my undergraduate thesis. I have investigated the technology in terms of concepts and implementation, while also garnering some first-hand software development (Objective C over Project Builder and Interface Builder) experience that would utilize the technology. While searching for opportuities for the past six months, I am sending this e-mail with the hope that it might find someone who's looking for someone with such experience or may have some suggestions. Thank you in advance. Sincerely, Hussain H. Bandukwala ======================================================================== Hussain H. Bandukwala, 13947 Carthage Cir., Burtonsville, MD - 20866.

Getting memory statistics of remote device
by Nikita Zhuk 11 Nov '03

11 Nov '03

Hello, I would like to know how to retrieve information about memory state of remote device. My goal is to ask the device how much free space does it have (on the drive where files uploaded via Bluetooth are saved), so application could warn the user if one tried to upload too large file on the device. Apple hasn't done that check in "Send file..."-command of their Bluetooth File Exchange application, so I can start uploading 60 megabyte file on my cell phone (Nokia 3650), and my phone will start giving errors when its memory gets full. Any help will be greatly appreciated. -- Nikita Zhuk Mac OS & Web Developer http://www.maczsoftware.com/blogs/nzhuk/ nikita(a)maczsoftware.com _______________________________________________ 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.

Re: SCO layer for audio comms?

I'm very interested in a headset profile available in the bluetooth stack! Any headway on this would make my day!
