hi anyone can help me witha small sample code of opening raw hci socket (AF_BLUETOOTH) and reading raw data from that socket? i am trying to write my diploma in using bluetooth dongle to broadcast digital data. any help is wellcome. thanks peter -- Time is an illusion, lunchtime doubly so. -- The Hitchhiker's Guide to the Galaxy _______________________________________________ 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.

Acessing BT modules directly & multiple bluetooth modules
by Matthias Ringwald 24 Feb '04

24 Feb '04

hi maybe someone could give me a short answer to this: is it possible for an user-land application to access a connected BT module on the HCI USB layer ? Problem here is that apple bluetooth gets hold of the device. So is there a way to tell the system to free this BT module. from the developer/examples/kernel folder I lerned that I could write a KEXT that prevents the system to match against some usb devices. that's fine. but is this also possible dynamically ? another question: what happends if I plug in a second BT module ? in the system log I get something like: a bluetooth module already in use. so plugging 2 BT usb dongles allows me easily to access the second one, true? thanks, Matthias Ringwald ETH Zurich _______________________________________________ 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.

Hi, The way the Mac OS does this is very different then the BlueZ method on Linux. If you are refereeing to the HCITool inq command, then the information is available in the bluetooth system preference pane for any paired device. For inquiring in an application you have 2 options. You can use the Obj-C Bluetooth User Interface system, or the Carbon one. My suggestion will be to use the carbon one, so you don't need to worry about the Obj-C's language differences. The chat sever and client are good examples on how to use the bluetooth API, I have copied the relevant portions here for you. This specifies the actual class you want to use unsigned char gExampleChatServiceClassUUID[] = // 0DAD4365-5DF1-11D6-9F6E-00039353E858 { 0x0d, 0xad, 0x43, 0x65, 0x5d, 0xf1, 0x11, 0xd6, 0x9f, 0x6e, 0x00, 0x03, 0x93, 0x53, 0xe8, 0x58 }; If you wanted a simple Serial UUID then you can use this for example (this should work, but I haven't tested it) unsigned char gExampleChatServiceClassUUID[] = // 0DAD4365-5DF1-11D6-9F6E-00039353E858 { 0x11, 0x01 }; This creates a new service browser, where you can specify which options you want to give the user. // First, we create a service browser controller which will allow us to put up a panel to allow the user // to select a device and service. serviceBrowser = IOBluetoothServiceBrowserControllerCreate( kIOBluetoothServiceBrowserControllerOptionsNone ); This converts the above unsigned array to a proper UUID. The UUID is needed in this form to be passed to the service array. // Now we create an array with all the UUID we are interested in (in this case only our custom one): chatUUID = IOBluetoothSDPUUIDCreateWithBytes(gExampleChatServiceClassUUID, 16); Create an array which contains the different services that you want to match. If you want to work with more then one, put them in here. serviceArray = CFArrayCreate(NULL, (const void **)&chatUUID, 1, &kCFTypeArrayCallBacks); This actually creates a non-model (I always confuse this, but its a synchronous call, doesn't move till user goes ok/cancel) window with a list of currently known Bluetooth devices in the favorites and those that are in range. You can also use the pulldown menu to filter based on a specific class, mice, keyboards computers etc. // This call will return kIOReturnSuccess if the user has successfully selected a device and service that matches the // specified serviceArray. result = IOBluetoothServiceBrowserControllerDiscoverWithDeviceAttributes(serviceB rowser, &serviceRecord, NULL, serviceArray); When this returns you will either have an error in result, or you can use these commands to get the RFComm channel, and the actuall device you are connecting too. result = IOBluetoothSDPServiceRecordGetRFCOMMChannelID(serviceRecord, &rfcommChannelID); device = IOBluetoothSDPServiceRecordGetDevice( serviceRecord ); One major difference between the Bluez implementation and the Apple one, is that Apple requires an SDP record to be available and correct before it will connect. This will open a connection to the device on the RFComm channel specified in the SDP record. You can open multiple channels as needed using this method. The last two parameters specify the call back. The event listener is a method which allows you to handle anything that comes back on the channel. The self, is for specify which object/class will handle the callback. IOBluetoothDeviceOpenConnection(device, NULL, NULL) IOBluetoothDeviceOpenRFCOMMChannelSync(device ,&mRFCOMMChannelRef, rfcommChannelID, rfcommEventListener, (void*)self); The call back is handled by this method void rfcommEventListener( IOBluetoothRFCOMMChannelRef rfcommChannelRef, void *refCon, IOBluetoothRFCOMMChannelEvent *event ) which in turn calls - (void)handleIncomingEvent:(IOBluetoothRFCOMMChannelEvent *)event To handle all incoming data. Finally the method - (BOOL)sendData:(void*)buffer length:(UInt32)length Is used to actually send data across the bluetooth link. All of the code above is pulled from the RFComm chat sample, with a some additional information. If you need anything else just ask!

Sir, Iam completely new to MAC environment and just started exploring Bluetooth framework.I developed a application based on bluez (bluetooth stack for linux) and I want to port(or may be to write everything from scratch using Objective-C and cocoa frameworks)this to MAC. In the Bluetooth framework,I could not find any reference related to Inquiry command and when I browsed through the archives,there were mails saying that we have to use BluetoothUI framework to accomplish this.But I could not find any sample source code regarding this. I checked out the rfcomm and obex examples in the documentation and it would be great it anyone can provide some sample code and any advice in order to perform "Inquiry" and filter results based on "Class of Device". Hope to hear from you regarding this. Thank You. __________________________________ Do you Yahoo!? Yahoo!

Re: Mac as Bluetooth Headset
by Riccardo De Menna 17 Feb '04

I've had the same idea. Why can't we just use the mac to talk into the phone? What would be necessary to force the mac to behave as the headset and not the audio gateway? Can't we do it with the current stack?

Writing the message below it suddenly occurred to me that the publishers of the ADC news letter misinterpreted information about the posting of the Bluetooth SDK updates. What should be on the ftp site is as follows: 1. Mac OS X Bluetooth SDK 1.3.3.pkg - (for Mac OS X v.10.2.x (aka Jaguar)) 2. Mac OS X Bluetooth SDK 1.4.1.pkg - (newly updated for Bluetooth 1.4.1 software on Mac OS X v.10.3.x (aka Panther)) 3. Mac OS X Bluetooth SDK 1.5.pkg - (newly updated for Bluetooth 1.5 software on Mac OS X v.10.3.x (aka Panther)) We should have the site and documentation fixed shortly. Sorry about the confusion.

As you may have seen in the ADC News #385 letter posted February 14th, the Bluetooth SDKs for Jaguar (1.4.1) and Panther (1.5) have been updated. These versions should be installed if you have the corresponding Bluetooth update installed, but they are fixed so as not to interfere with earlier updates.

Re: Mac as Bluetooth Headset

What I have always thought of as a very nifty application would be to integrate iChat with a bluetooth phone. All the 'bits' are there just the Bluetooth drivers need to be updated, and the bits need to be glued together. At the moment, the phone book is in the Mac, and shared with the phone (well, for modern bluetooth phones), the mac has a speaker and a mic. Would make for a nice handsfree kit. Just food for thought.
