CBC - CalcBtChat

This program was made with the desire that on each test all phones of students are on a single bench during the test.

Proper use of the application:
1) For Teachers: show this app to students and explain to them that they must have their calculators (not on the phone).
2) For students: show this app the teacher and explain how it works.
3) Use it as Bluetooth chat program during the break.

Wrong usage:
Bluetooth chat program during the test.

Buttons:
Con - connect, Vis - make visible, del -delete received string, N/T switch number/ text, snd - send text, curr - confirm current letter if next one is on same button (DEF), C - delete local text, dot - delete last letter in local text.
This app is not working as a calculator (for now)
