Please follow the steps in the developer's guide on how to get started:
You should read section "4." carefully.
4. You need to install some native DLLs
BlueToolsMS.dll (Microsoft stack support).
BlueToolsWC.dll (WidComm stack support).
BlueToolsWC150.dll (Extended WidComm stack support).
All those DLLs should be copied to \Windows on your device. The easiest way to do this is to transfer BlueTools.arm.CAB file to the device and run it. Or you can copy the DLLs to the same directory as your application (EXE).
Note! ARM and XScale are the same type of processor. If you need DLLs for another processor, please contact us.
You find the native DLLs and .NET 1.0 resources under:
Start -> Program -> Franson BlueTools SDK -> .NET Compact Framework 1.0 -> Samples & Assemblies
And .NET 2.0 samples and assemblies under:
Start -> Program -> Franson BlueTools SDK -> .NET Compact Framework 2.0 -> Samples & Assemblies
