Yes, thanks. I gotten that. What I meant is more like some instructions how to get the system running, this what I am trying to achieve. Now, as you can see there is a lot of information spread all around and I have hard time to get them together in a meaningful picture. What troubles me the most is these kind of information that are missing, for example : - start this application first, then this one - LOST message is OK - there is no SIM simulated, and you can not do anything without SIM, which is not supported on the master - connect this to this to get logs in Wireshark - etc... Some kind of a tutorial that would prevent every starter to get stuck. Thanks for your help, things are beginning to be clearer. BR, Drasko
