Hi,

I have HTC T8585, and i'm trying ton install on it a windows mobile application that i developed it using c# .  When my application starts it should connect to bluetooth, what is happening that i'm getting a message that says "Couldn't connect to Bluetooth due to: No supported Bluetooth protocol stack found". i'm using InTheHand.Net.Personal.dll 2.5 and 32feetWidcomm.dll 2.5 (i cant add it in add reference). and this function BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable give me nullreference error.

Please i need help as soon as possible.

The 32feetWidcomm.dll is a native DLL and thus shouldn't be added as a .NET assembly reference.  It just needs to be next to the .exe at runtime:

To enable the Widcomm support, in brief the 32feetWidcomm.dll native DLL need to be present at runtime in the same folder as the main library assembly (InTheHand.Net.Personal.dll) and the application itself.  As a native DLL it cannot be referenced at compile-time like a normal managed .NET assembly

I'm somewhat surprised that you're getting that exception message on 2.5, I'd have expected the exception to be:

Normal 0 false false false /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}

    PlatformNotSupportedException: Widcomm stack seems to be present, need to install 32feetWidcomm.dll alongside.

Thats right, this is what i'm getting "Widcomm stack seems to be present, need to install 32feetWidcomm.dll alongside" , but i did what you are saying to put 32feetWidcomm.dll  in the same folder that has .exe appliaction in the mobile. But i'm getting all these problems !!

 What version of 32feetWidcomm.dll file are you using?  From a release, from what folder?

I'm using the last version but still i have the same issue.

I'm using last version of 32feetWidcomm.dll  but still not working !!

I was beginning to think that there was some problem, but then this guy got it to work http://inthehand.co.uk/forums/t/3391.aspx

Can you take the app.config file from the "32feet and widcopmm" doc in the release, edit it to make sure that the reportAllErrors property is true, copy it next to the .exe (and two .dlls),  and make sure it has the correct name (32feet.config).  What does it report?  Otherwise run it in the debugger with 'show all thrown exceptions' enabled.
