【Sors Miftuħ】 DWIN Screen u Telefon Android Two-way Linkage Control Music Playback

–Mill-Forum tal-Iżviluppaturi DWIN

Din il-kwistjoni għalik biex timbotta l-każ ta 'sors miftuħ rebbieħ tal-forum tal-iżviluppaturi DWIN - skrin DWIN u telefon Android two-way linkage control daqq tal-mużika. L-inġiniera permezz tal-modulu Bluetooth biex jiksbu l-iskrin intelliġenti DWIN u l-interazzjoni tad-dejta tat-telefon Android, l-utenti jistgħu faċilment jikkontrollaw it-telefon Android, USB flash drive fid-daqq tal-kanzunetta, nieqaf, ibiddel il-kanzunetta u l-issettjar tal-ħoss, esperjenza skrin intelliġenti u telefon Android żewġ- mod konvenjenti kontroll.
