【Open Source】 DWIN Bildschierm an Android Telefon Zwee-Wee Linkage Kontroll Musek Playback

-Vum DWIN Entwéckler Forum

Dëst Thema fir Iech de Präis-Zouschlag Open-Source Fall vun DWIN Entwéckler Forum ze drécken - DWIN Écran an Android Telefon zwee-Wee Linkage Kontroll Musek playback. Ingenieuren duerch de Bluetooth Modul fir den DWIN intelligenten Ecran an Android Telefon Daten Interaktioun z'erreechen, kënnen d'Benotzer einfach den Android Telefon kontrolléieren, USB Flash Drive am Song Play, Paus, änneren d'Lidd an Toun Astellungen, Erfahrung intelligent Écran an Android Telefon zwee- Manéier bequem Kontroll.
