Aperi Source】 DWIN Screen et Android Phone Duo-modo Linkage Imperium Musica Playback

-From DWIN Developer Forum

Hic exitus tibi est ut causam conciliandae open-fontis repellas forum elit DWIN - DWIN screen et Android telephonum duo-modo nexus control musicae playback. Machinatores per modulum Bluetooth ad DWIN screen intelligentium et Android telephonicum commercium consequendum, utentes facile moderari telephonum Android, USB mico coegi in cantu fabulae, morae, cantus et occasus soni mutant, intelligentes screen et Android telephonum duo- modo opportunum imperium.
