CySmart DLL Import @Unity

[TaDa_1407706]

Is there anyone can import CySmart DLL into Unity Project???

I know it's a little bit Unity's issue, but I also want to get your advice.

At first, I've already confirmed that below DLLs work well by C# WPF project.

(I confirmed that it open CY5677 dongle's comm port without problem.)

• cybleautobase.dll
• cyblecommonbase.dll
• cybledonglecommunicator.dll

Then I bring those DLLs into Unity project, and confirmed "there is no error message".

But the problem is that DLL doesn't work at all.(TryGetCySmartDongleCommunicator Function returns NULL)

I've tried to modify below configuration options, but the situation doesn't change.

(Build Setting→Player Setting→Other Setting →Configuration)

• Runtime version : 4.0 -> 3.5 (rebuild but NG)
• Scripting Backend : Mono->IL2CPP ( Still NG)
• Api Compatibility : 4.0 -> 2.0 (still NG)

My Environment

• Unity 2018.4.16f1 personal
• Microsoft Visual Studio Community 2019　Version 16.5.1
• Windows 10 1903

DLL information (confirmed at VS2019's property window)

• Version : 1.3.0.8
• Runtime Version: v2.0.50727
