Monga tikudziwira, gawo la Bluetooth lagawidwa m'mitundu iwiri: Classic Bluetooth (BR/EDR) ndi Bluetooth Low Energy (BLE). Pali mbiri zambiri za Classic Bluetooth ndi BLE: SPP, GATT, A2DP, AVRCP, HFP, ndi zina zotero. Pakutumiza deta, SPP ndi GATT ndizomwe zimagwiritsidwa ntchito kwambiri pa Classic Bluetooth ndi BLE mbiri motsatira.
Mbiri ya SPP ndi chiyani?
SPP (Serial Port Profile) ndi mbiri yakale ya Bluetooth, SPP imatanthauzira zofunikira pazida za Bluetooth zomwe zimafunikira kuti mukhazikitse kulumikizana kwa chingwe chotsatsira pogwiritsa ntchito RFCOMM pakati pa zida ziwiri za anzawo. Zofunikira zimawonetsedwa malinga ndi ntchito zomwe zimaperekedwa ku mapulogalamu, komanso kufotokozera mawonekedwe ndi njira zomwe zimafunikira kuti zigwirizane ndi zida za Bluetooth.
Mbiri ya GATT ndi chiyani?
GATT (Generic Attribute mbiri ndi mbiri ya BLE, imatanthawuza mafotokozedwe a zida ziwiri za BLE kuti azilankhulana kudzera mu Utumiki ndi Makhalidwe, mbali ziwiri za GATT kulankhulana ndi Client / Server ubale, Peripheral ndi GATT Server, Central ndi GATT Client, mauthenga onse , onse amayambitsidwa ndi kasitomala, ndikulandila yankho kuchokera ku Seva.
SPP+GATT combo
SPP ndi GATT akugwira ntchito yopatsira deta, tiyenera kuzindikira kuti tikamagwiritsa ntchito gawo la Bluetooth polumikizana ndi pulogalamu yam'manja, pa foni yam'manja ya iOS, BLE (GATT) ndiyo njira yokhayo yomwe imathandizidwa ndi njira ziwiri zotumizira deta zomwe zili zaulere. gwiritsani ntchito, pa foni yam'manja ya Android, imathandizira onse SPP ndi GATT, kotero ndikofunikira bwanji kuti gawo lithandizire SPP ndi GATT.
Pamene gawo la Bluetooth limathandizira SPP & GATT, zikutanthauza kuti ndi gawo la Bluetooth-mode-module. Ma module aliwonse ovomerezeka a Bluetooth amitundu iwiri?
Ma module awiriwa sali oyenera kugwiritsa ntchito kwanu? Musazengereze kulumikizana ndi Feasycom tsopano!
