Hi the string communication is still new to me I understand that the android app is sending a number to the arduino for the digital buttons but what happens after 1-9 have been used when I send 10 I get 1 on the arduino side. I guess the question really is how do you send two digits and the arduino not just take the first?
I think you are using an old example code. The new code can process longer strings. Try the new code and new example.
