Raws li peb paub, Bluetooth module tau muab faib ua ob hom: Classic Bluetooth (BR / EDR) thiab Bluetooth Tsawg Zog (BLE). Muaj ntau ntau yam ntawm Classic Bluetooth thiab BLE: SPP, GATT, A2DP, AVRCP, HFP, thiab lwm yam. Rau cov ntaub ntawv kis tau tus mob, SPP thiab GATT yog cov feem ntau siv Classic Bluetooth thiab BLE profiles feem.
SPP profile yog dab tsi?
SPP (Serial Port Profile) yog Classic Bluetooth profile, SPP txhais cov kev cai rau Bluetooth li tsim nyog rau kev teeb tsa emulated serial cable sib txuas siv RFCOMM ntawm ob tug phooj ywg. Cov kev cai yuav tsum tau qhia nyob rau hauv cov nqe lus ntawm cov kev pab cuam muab rau cov ntawv thov, thiab los ntawm kev txhais cov yam ntxwv thiab cov txheej txheem uas yuav tsum tau rau interoperability ntawm Bluetooth li.
GATT profile yog dab tsi?
GATT (Generic Attribute profile yog BLE profile, nws txhais cov lus qhia tshwj xeeb rau ob lub BLE cov khoom siv sib txuas lus los ntawm Kev Pabcuam thiab Cov yam ntxwv, ob tog ntawm GATT kev sib txuas lus yog Client / Server kev sib raug zoo, Peripheral yog GATT Server, Central yog GATT Client, tag nrho cov kev sib txuas lus , ob qho tib si yog pib los ntawm Client, thiab tau txais cov lus teb los ntawm Server.
SPP + GATT combo
SPP thiab GATT tab tom ua lub luag haujlwm ntawm kev xa cov ntaub ntawv, peb yuav tsum pom tias thaum siv Bluetooth module rau kev sib txuas lus nrog lub xov tooj ntawm tes, rau iOS smartphone, BLE (GATT) yog tib txoj kev txhawb nqa ob-txoj kev cov ntaub ntawv xa tawm profile uas pub dawb rau. siv, rau Android smartphone, nws txhawb nqa ob qho tib si SPP thiab GATT, yog li qhov tseem ceeb npaum li cas yog qhov module txhawb nqa SPP thiab GATT.
Thaum Bluetooth module txhawb nqa SPP & GATT, nws txhais tau tias nws yog Bluetooth dual-mode module. Puas muaj kev pom zoo Bluetooth dual-hom modules?
