E mohio ana tatou, kua wehea te waahanga Nihokikorangi ki nga momo e rua: Nihokikorangi Tauhira (BR/EDR) me te Nihokikorangi Low Energy (BLE). He maha nga korero mo te Nihokikorangi Tauhira me te BLE: SPP, GATT, A2DP, AVRCP, HFP, me etahi atu.
He aha te kōtaha SPP?
Ko te SPP (Serial Port Profile) he Kotaha Nihokikorangi Tauhira, ka tautuhia e SPP nga whakaritenga mo nga taputapu Nihokikorangi e tika ana mo te whakatu i nga hononga taura rangatū tauira ma te whakamahi i te RFCOMM i waenga i nga taputapu hoa e rua. Ko nga whakaritenga e whakaatuhia ana mo nga ratonga e whakaratohia ana ki nga tono, me te tautuhi i nga ahuatanga me nga tikanga e hiahiatia ana mo te mahi tahi i waenga i nga taputapu Nihokikorangi.
He aha te kōtaha GATT?
GATT (Generic Attribute profile is a BLE profile, it define specifications for two BLE devices to communication through Service and Characteristics, ko nga taha e rua o te korero GATT he hononga Kiritaki/Tumaumau, Peripheral ko GATT Server, Central ko te Kaitaki GATT, nga korero katoa. , na te Kiritaki i timata, ka whiwhi whakautu mai i te Tūmau.
Paheko SPP+GATT
Ko te SPP me te GATT te mahi ki te tuku raraunga, me kite tatou i te wa e whakamahi ana i te kōwae Nihokikorangi mo te whakawhitiwhiti korero me te taupānga pūkoro, mo te waea atamai iOS, ko te BLE (GATT) ko te BLE (GATT) anake e tautokohia ana e rua-ara nga korero tuku korero e waatea ana. whakamahi, mo te atamai Android, e tautoko ana i te SPP me te GATT, no reira he aha te nui o te tautoko o te kōwae i te SPP me te GATT.
Ina tautoko tetahi kōwae Nihokikorangi i te SPP me te GATT, ko te tikanga he kōwae aratau-rua Nihokikorangi. Ētahi kōwae aratau-rua Nihokikorangi tūtohutia?
Ko enei waahanga e rua kaore e tino pai mo to tono? Kaua e mangere ki te whakapā atu ki a Feasycom inaianei!
