Hi Julien, IOBluetoothNSStringToDeviceAddress does not allocate a BluetoothDeviceAddress, it just fills it up , so It should be: devAddressString=@"00-08-c6-13-45-e9"; BluetoothDeviceAddress devAddress; IOBluetoothNSStringToDeviceAddress(devAddressString, &devAddress); ..

I'm just trying to build and run a small App I made using BT :IOBluetoothUtilities.h and particularly this function IOReturn IOBluetoothNSStringToDeviceAddress( NSString * inNameString, BluetoothDeviceAddress * outDeviceAddress ); But it seems it's not working, does someone experienced problems with it? here's my code : NOte that the device address was obtained previously : so it's good. devAddressString=@"00-08-c6-13-45-e9"; BluetoothDeviceAddress * devAddress=nil; NSLog(devAddressString); IOBluetoothNSStringToDeviceAddress(devAddressString, devAddress); BtDevice=[IOBluetoothDevice withAddress:devAddress]; NSLog(@"the new name %s ",[BtDevice getName]); here's what happens: 00-08-c6-13-45-e9 the new name (null) And it bugs if I want to obtain the new device Address' Thanks for helping...
