Unity3d DLL issues

Okay, to start with, I have finally gotten the trio of DLL systems to stop complaining about versions, and load into Unity as a plugin set.

This includes:

MbientLab.MetaWear.dll
MbientLab.MetaWear.NetStandard.dll
Warble.NetStandard

As of now, the problem I have is Warble:

System.DllNotFoundException: warble
at (wrapper managed-to-native) MbientLab.Warble.Bindings.warble_gatt_create_with_options(int,MbientLab.Warble.Bindings/Option[])
at MbientLab.Warble.Gatt..ctor (System.String mac, System.String hci, System.String addrType) [0x00090] in C:\Users\fooli\Downloads\Warble.NET-master\Warble.NetStandard\Gatt.cs:48

UnityEngine.Debug:Log(Object)
d__1:MoveNext() (at Assets/Plugins/MbientLab/MbientLab_Bridge.cs:35)
System.Runtime.CompilerServices.AsyncVoidMethodBuilder:Start(d__1&)
MbientLab_Bridge:Start()

I'm assuming something did not compile properly with Warble? Or is something else missing I'm not understanding.
I normally do not compile DLL sets like this, so I'm a bit out of my element.

The above error is caused by the runtime line:

        metawear = MbientLab.MetaWear.NetStandard.Application.GetMetaWearBoard("C2:BD:D8:B2:EF:35");

Anyone want to tell me why this is a simple issue, and I'm an idiot for not understanding the solution?
