Njengoko siyazi, imodyuli yeBluetooth ihlukaniswe kwiindidi ezimbini: I-Classic Bluetooth (BR / EDR) kunye neBluetooth Low Energy (BLE). Kukho iiprofayili ezininzi ze-Classic Bluetooth kunye ne-BLE: i-SPP, i-GATT, i-A2DP, i-AVRCP, i-HFP, njl. Ukuhanjiswa kwedatha, i-SPP kunye ne-GATT zezona zisetyenziswa rhoqo kwi-Classic Bluetooth kunye neeprofayili ze-BLE ngokulandelanayo.
Yintoni iprofayile ye-SPP?
I-SPP (iProfayili ye-Serial Port) yiprofayili ye-Classic yeBluetooth, i-SPP ichaza iimfuno zezixhobo zeBluetooth eziyimfuneko ukuseta uqhagamshelo lwentambo ye-serial efanisiweyo usebenzisa i-RFCOMM phakathi kwezixhobo zontanga ezimbini. Iimfuno zibonakaliswa ngokweenkonzo ezibonelelwa kwizicelo, nangokuchaza iimpawu kunye nemigaqo efunekayo ukuze kubekho ukusebenzisana phakathi kwezixhobo zeBluetooth.
Yintoni iprofayile yeGATT?
I-GATT (iprofayili ye-Generic Attribute yiprofayili ye-BLE, ichaza iinkcukacha zezixhobo ezimbini ze-BLE ukunxibelelana ngeNkonzo kunye ne-Characteristic, amaqela amabini onxibelelwano lwe-GATT lubudlelwane boMthengi / iServer, i-Peripheral yi-GATT Server, i-Central yi-GATT Client, zonke ezonxibelelwano. , zombini ziqaliswe nguMthengi, kwaye zifumana impendulo kumncedisi.
SPP+GATT combo
I-SPP kunye ne-GATT zidlala indima yokudlulisa idatha, kufuneka siqaphele ukuba xa usebenzisa imodyuli yeBluetooth yokunxibelelana ne-app yeselula, ye-smartphone ye-iOS, i-BLE (GATT) kuphela iprofayili yokuhanjiswa kwedatha yendlela-mbini ekhululekile sebenzisa, kwi-smartphone ye-Android, ixhasa zombini i-SPP kunye ne-GATT, ngoko kubaluleke kangakanani imodyuli ixhasa zombini i-SPP kunye ne-GATT.
Xa imodyuli yeBluetooth ixhasa zombini iSPP & GATT, oko kuthetha ukuba yimodyuli yeBluetooth yemodyuli-mbini. Naziphi na iimodyuli ezicetyiswayo zeBluetooth ezimbini?
Ezi modyuli zimbini azifanelekanga kakhulu kwisicelo sakho? Ungalibazisi ukunxibelelana Feasycom ngoku!
