Bluetooth issue

Hi,

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

enabled devices using

WSALookupServiceBegin, WSALookupServiceNext methods.

WSALookupServiceBegin method returns -1.

I tried discovering the devices using BluetoothFindFirstDevice and

BluetoothFindNextDevice 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
