Where are your procedures BackgroundTask and BackgroundWork?
There does not exist a Clock2.timer event, it should be Clock2 Timer
Taifun
What exactly is that radio link?
Some observations:
-
you should rename your procedure Background to BackgroundTask and add an argument x, also you forgot to initialize the Clock component. .
Evaluate but ignore result Clock1
And give the procedure you are registering another name, for example timer -

And: don’t forget to setup the timer event handler… the question however is, what exactly are you trying to do there?

Can I create multiple Tasks? “CreateProcess”
I need to create 4 to be called
Why do you think you need that?
What about creating only one process, which triggers one procedure to setup everything you need?

I am getting the following error when Initiating: Attempt to invoke virtual method 'int.java.lang.Integer.intValue()' on a null object reference
you are using an older version of Itoo… use the current version
