Спасибо за урок!

Видос нормальный но музыка напрягает.

Это ад какой-то. После этого хочется выкинуть bt модуль, и Ардуино. И телефон тоже. Спасибо, урок хороший, но ничерта пока не ясно. Будем разбираться.

Огромное СПАСИБО! Но исходник не хочет открываться через андройд студио..

Подскажи пожалуйста как с тобой связаться?
