Exception in OPCUAConnection.Connect on Hololens

industry40lab vor 1 Monat in OPCUA4Unity aktualisiert von Thomas gestern um 01:20 4


I am using OPCUA4Unity in my Hololens Unity project. An exception is thrown when I try to connect to an OPCUA server from the Hololens. Here is the output:

"The type initializer for 'Opc.UaFx.Client.OpcClient' threw an exception. at game4automation.OPCUAConnection.Connect () [0x00000] in <00000000000000000000000000000000>:0
at game4automation.OPCUA_Interface.Connect () [0x00000] in <00000000000000000000000000000000>:0"

I am able to connect just fine in Unity Editor, but not when connecting in Hololens.

I have ensured that the build settings are correct (IL2CPP, .NET 2.0 compatibility), and have set the permissions to allow internet access in Hololens. I am on Unity 2018.4.8f1, and have tried upgrading my project to 2019.1.14f1 but that did not fix the issue.

Let me know if you need more information!



Nö sorry - we still don’t know how to compile for Hololens

Hi, we encountered similar issues with a Hololens 1 of a customer and we were not able to solve it. We are waiting for Hololens 2 to to be able to test it.  Because it is working on all other devices like iOS and android we have currently no idea how to get it working.  If you have any idea it would be welcome.   If you want to use our solution only with Hololens and if you are not happy with it we can refund you the money. 

Best Regards


Hello everybody! Is there any news on that problem? Thanks.
