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 ! _______________________________________________ bluetooth-dev mailing list | bluetooth-dev@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/bluetooth-dev Do not post admin requests to the list.
