i need to push a button on A and get a led blink on B, once blinked B tells A the job was done successfully and it makes A blink a led, and vice versa.

after making one of them server and one of them client it works when i go from client to server but not from server to client, I appreciate any help since im not very good with code and i been working with this for days without any result, if someone knows a way to do this with a different code its ok just as long as i can do that.
