Here is the code I use : + (NSArray*)devicesWithService:(BluetoothClassOfDevice)service { IOBluetoothDevice *currentDevice; NSArray *devices = [ IOBluetoothDevice pairedDevices]; NSEnumerator *e = [devices objectEnumerator ]; NSMutableArray *result = [NSMutableArray array]; while (currentDevice = [ e nextObject ]) { //10100100000001000000100 T610 //00000000010010110000000 MX900 //NSLog(@"%i : %@",[ device getClassOfDevice ], [ device getName ]); if ([ currentDevice getClassOfDevice ] & service) [result addObject: [NSDictionary dictionaryWithObjectsAndKeys:[currentDevice getName],@"name",[currentDevice getAddressString],@"address",nil]]; } return [[result copy]autorelease]; } I do not use standard bluetooth selection dialog, beacause I just need telephones, but as far as I know, you need the same :-) Pass it 0x400000 to get phone class device Le 13 juil. 04, ` 11:21, Aurilien Hugeli a icrit :

hi !

Apple's BT team is really helpful (as i experienced myself 2 weeks ago

is SF ;-) ) so i have another question for them (or any other list

member !)

i would like my BT device selector to filter only phone/telephony

devices.

i've read the doc (and the headers this time !) and found that i should

use something like :

deviceSelector = [[IOBluetoothDeviceSelectorController alloc] init];

[deviceSelector setSearchAttributes:<#(const

IOBluetoothDeviceSearchAttributes *)searchAttributes#>];

[deviceSelector runModal];

// test the return of runModal

[deviceSelector getResults];

The problem for me is the searchAttributes structure... i'm not really

familiar with low level stuff and must admit i'm lost...

struct IOBluetoothDeviceSearchAttributes

{

IOBluetoothDeviceSearchOptions options; // Options.

IOItemCount maxResults; // Maximum number of results you

desire. 0 means infinite.

IOItemCount deviceAttributeCount;

IOBluetoothDeviceSearchDeviceAttributes *attributeList;

};

I don't really care of the options, maxResults. Only the attributeList

is important :

struct IOBluetoothDeviceSearchDeviceAttributes

{

BluetoothDeviceAddress address; // 00 08 22 44 AB 56, etc.

BluetoothDeviceName name; // "Al Yankovic's Phone", etc.

BluetoothServiceClassMajor serviceClassMajor; // Networking,

Rendering, etc.

BluetoothDeviceClassMajor deviceClassMajor; // Computer, Phone,

Audio, etc.

BluetoothDeviceClassMinor deviceClassMinor; // Desktop, cordless,

headset, etc.

};

with my current testing, i only need to set the deviceClassMajor and

deviceClassClassMinor to specific values to discover BT enabled

cellular phones (the serviceClassMajor seems to differ with each

brand...)

can i create my IOBluetoothDeviceSearchAttributes with NULL for each

members of the structure (except attributeList of course) ? or 0 ? (the

headers comments are not really clear on this point)

how to create my IOBluetoothDeviceSearchDeviceAttributes struct ??

any address, any name, how to get that ? i don't see any

kBluetoothServiceAddressAny, kBluetoothServiceNameAny ...

any serviceClassMajor (kBluetoothServiceClassMajorAny) would be ok, i

just need specific deviceClassMajor/Minor...

can you help me ?

thanks for all your help !
