Bluetooth ndi mulingo waukadaulo wotumizira ma data osakhalitsa opanda zingwe pakati pa zida zomwe zili ndi tchipisi togwirizana. Pali matekinoloje awiri akuluakulu mkati mwa Bluetooth core specification-Bluetooth classic ndi Bluetooth Smart (Bluetooth Low Energy). Matekinoloje onsewa amaphatikiza ntchito monga kupeza ndi kulumikizana, koma sangathe kulumikizana wina ndi mnzake. Chifukwa chake, pali kusiyana pakati pa Bluetooth single-mode ndi Bluetooth wapawiri-mode pa hardware module. Bluetooth pakugwiritsa ntchito mafoni a m'manja tsiku lililonse ndi Bluetooth-mode-mode, yomwe imatha kuthandizira Bluetooth Classic ndi Bluetooth Low Energy.
Bluetooth Classic
Bluetooth Classic idapangidwa kuti izisamutsa deta yanjira ziwiri mosalekeza ndikugwiritsa ntchito kwambiri (mpaka 2.1 Mbps); zogwira mtima kwambiri, koma kwa mtunda waufupi. Choncho, ndi njira wangwiro pa nkhani ya akukhamukira zomvetsera ndi kanema, kapena mbewa ndi zipangizo zina zofunika mosalekeza, burodibandi ulalo.
Ma protocol omwe amathandizidwa ndi Bluetooth akale: SPP, A2DP, HFP, PBAP, AVRCP, HID.
Mphamvu Zochepa za Bluetooth
Kafukufuku wa SIG pazaka khumi zapitazi afuna kukonza magwiridwe antchito a Bluetooth pakugwiritsa ntchito mphamvu, kubwera kudzawonetsa mu 2010 muyezo wa Bluetooth Low Energy (BLE). Bluetooth Low Energy ndi mtundu wamagetsi otsika kwambiri wa Bluetooth womwe umapangidwira masensa otsika mphamvu ndi zina. Ndi yabwino kwa mapulogalamu omwe safuna kulumikizidwa mosalekeza koma zimadalira moyo wautali wa batri.
NTCHITO IKULU YA BLUETOOTH CLASSIC NDI BLE
Bluetooth Classic ndiyabwino pazogulitsa zomwe zimafunikira kusuntha kosalekeza kwa mawu ndi kufalitsa deta, monga:
- Mahedifoni opanda zingwe
- Fayilo kusamutsidwa pakati pa zipangizo
- Makiyibodi opanda zingwe ndi osindikiza
- Oyankhula opanda zingwe
Bluetooth Low Energy (Bluetooth LE) ndiyoyenera kugwiritsa ntchito IoT monga:
- Monitoring masensa
- BLE Beacons
- Kutsatsa kwapafupi
Mwachidule, Bluetooth Classic si mtundu wachikale wa BLE. Bluetooth Classic ndi Bluetooth Low Energy amakhalapo ndipo amagwiritsidwa ntchito zosiyanasiyana. Zonse zimatengera zosowa zosiyanasiyana za aliyense!
