【Loharanom-baovao】 DWIN Screen sy Android Phone Roa-dalana Linkage Control Playback Music

– Avy amin'ny DWIN Developer Forum

Ity olana ity ho anao hanosehana ny tranga loharano misokatra nahazo mari-pankasitrahana an'ny forum mpandrindra DWIN - efijery DWIN sy telefaona Android manara-maso ny fandefasana mozika amin'ny fomba roa. Injeniera amin'ny alalan'ny Bluetooth Module mba hahatratra ny DWIN manan-tsaina efijery sy ny finday Android fifandraisana angon-drakitra, mpampiasa dia afaka mora foana hifehy ny Android finday, USB tselatra fiara ao amin'ny hira filalaovana, fiatoana, hanova ny hira sy feo toe-javatra, traikefa manan-tsaina efijery sy Android finday roa- fomba fanaraha-maso mety.

(1) Ny seranan-tsambo serial T5L dia mifandray amin'ny maody Bluetooth mba hanovana ny toetry ny playback, hametraka ny volume ary hamaky ny sata Bluetooth, ny ampahany amin'ny fehezan-dalàna dia toy izao manaraka izao:
