an application which sends a '1' to arduino to start a task like blinking leds or something else like relays.
i want to make app easy to use not like you are trying to first find BT then choose and connect but as i open app it should have already connected and ready to send a '1'. to arduino. But i will manage no urgency not so important for me.

just frst connect to the device of your choice using the mac address and then send the "1"
you might want to try something anf if you got stuck, post a screenshot of your relevant blocks...
