– Mai ka DWIN Developer Forum

ʻO kēia pilikia no ʻoe e hoʻokau i ka hihia open-source lanakila-lanakila o DWIN developer forum - DWIN pale a me ke kelepona Android ʻelua ʻaoʻao e hoʻokele i ka pāʻani mele. ʻO nā mea hoʻohana ma o ka Bluetooth module e hoʻokō i ka DWIN naʻauao pale a me ka Android kelepona ʻikepili pili, hiki i nā mea hoʻohana ke hoʻokele maʻalahi i ke kelepona Android, USB flash drive i ka pāʻani mele, hoʻomaha, hoʻololi i ke mele a me nā hoʻonohonoho kani, ʻike i ka pale akamai a me ke kelepona Android ʻelua- ala oluolu mana.
