D DWIN dörediji forumyndan
Bu mesele, DWIN dörediji forumyň baýrakly açyk çeşmesini - DWIN ekrany we Android telefony iki taraplaýyn baglanyşyk gözegçilik saz çalmagy üçin itergi berer. DWIN akylly ekrany we Android telefon maglumatlary özara täsirini gazanmak üçin Bluetooth modulynyň üsti bilen inersenerler, ulanyjylar Android telefonyny, aýdym oýnamakdaky USB fleş diskini aňsatlyk bilen dolandyryp bilerler, durup bilerler, aýdym we ses sazlamalaryny üýtgedip bilerler, akylly ekrany we Android telefonyny başdan geçirip bilerler- amatly gözegçilik ýoly.
