Hi Nemanja, the work function is called by the scheduler, which only calls the work function, if it has some samples to process. So if your block is not part of the flow graph (which it isn't since you have no input or output stream) it will not get called. You could either create a Thread in the block's constructor which will call the work function (the start/stop functions seem to not being called either), or you could try the new message passing interface, where you can register a callback function that is called whenever a new message arrives.
