LUA debug

Hi,
isn't somewhere a tutorial/ video that shows how to use
Debugging applications in the Emulator (V5.00 and newer)
with ZeroBrane, I don't understand why I'm unable to hit breakpoints in init and loop.
Thanks

To hit breakpoints in loop function, add at the begin of loop function
require("mobdebug").on()
and before the end
require("mobdebug").off()

and than breakpoints within loop function work....
