Hi Erik, Many thanks for your help. I am sending a file of 1M over the bluetooth interface (which I thought it would be enough) but I will try with a bigger file. However I still have a dough. You say that the profiler looks at which function is running at particular points in time. Do you know what is the frequency the profiler does this? Is there any way to configure it?
