Dear UA Team,
I know that my question could appear a bit silly but I'm a newbie and I'm stuck with the following problem.
I'm using OPC UA SDK for your preferred language (C++ under linux). I've compiled all the servers and clients in server_gettingstarted/ and client_gettingstarted/, respectively. In a terminal, I launch server_lesson07 and in another terminal clent:lesson06. The client performs the connection with the server but when it start executing read and write, the following error message is shown:
** Try to call read for configured node ids
** Error: UaSession::read failed [ret=BadNothingToDo]
** Try to call write for configured node ids
** Error: UaSession::write failed [ret=BadNothingToDo]
I would be very grateful if you could help me in solving this problem. Any advice would be very useful for me.
Thanks in advance,
Diana

Re:Problems with Read and Write services in getting started examples of the SDK
From the following post:
http://www.unified-automation.com/forum ... y-step.htm
Does it mean that I cannot use the sample clients in clients_gettingstarted with the sample server in servers_gettingstarted? If so, is there an OPC UA Demo Server for linux?
Thanks,
Diana

Re:Problems with Read and Write services in getting started examples of the SDK
If you download the "C++ based OPC UA Client/Server SDK Bundle" that contains the DemoServer already.
That post should answer the rest of the question:
