I am trying to connect to an HC-05 but it just does nothing when i try to connect

i am having trouble using bluetooth, connecting to the hc05 is working, its just that when i press the pedal it doesn't sent number or the app is looking for the wrong thing, OR i'm using the wrong block. any help would be greatly aprieciated. a new problem has wedged itself in with the others,when i run the companian on screen one, it crashes. here is an aia file.
