add GUI dialogue box when event happens

Hi. I have a program (lots of functions) which creates an interface and I want to add a dialogue box saying "a router was found" every time the signal level reaches a certain threshold. Also, the signal value is retrieved in real time. My other question is : can I simulate a signal so that I can test the newly added "a router was found" dialogue box.

I attach my code in the hope that anyone can help and apologize that it's in romanian. The graph reads : "power spectral density", and the others are "energy detection parameters" and "data acquisition parameters".

Tiberius - consider using a msgbox such as

 msgbox('A router was found','Information')

whenever a signal reaches a certain threshold. (This will be a non-modal dialog; see the link for more details.)

You've only attached the m-file, so we can't run trough the GUI (would need the fig file for that) but you should be able to determine where in the code to add the message box logic.

Hi Geoff,

Thanks for your answer.

You should have posted this as an answer though!
