Bluetooth issue

Hi,

I am using Toshiba Bluetooth dongle. I tried to discover the bluetooth enabled devices using

WSALookupServiceBegin method returns -1.

I tried discovering the devices usingBluetoothFindFirstDevice andBluetoothFindNextDevice methods.

It returns the error code 126(module not found)

The dongle has Bluetooth Stack for Windows by Toshiba. and not the Microsoft Bluetooth Stack.

Can anyone please through some light on this issue? Can I use these methods to get the devices or should I use the SDK/API provided by Toshiba?

Thanks in advance

Sri
