I'm using open62541 to run a server on my embedded device(stm32f429), as a client I use UAExpert to connect to the server and borowse the nodes.

My problem is that I want to upload a file from Client "UAExpert" to my Server. I found a similiar question here on Stackoverflow but the answer didn't help me a lot.

I read the Annex C in part 5 but I couldn't understand how to implement the methods on the server side.

Can any one help me?

thnx in advance

I don't think that UAExpert supports this feature.

UAExpert can display Image from OPC UA Variable values from the Server (So actually if the Variable is writeable you could overwrite the value with you own)
