Hello,

According to the description, the server returns “Bad_InternalError” as the result of the write service. As you are writing a single attribute value with the UaClient.writeAttribute method, it’s easy to know that this single write request causes the error.

You should find out what’s going wrong in the server application. The error message only tells that something went wrong in the server and nothing more.
