Kulankhula za mfundo zochepa zaukadaulo waukadaulo wa bluetooth-1

Ndi chitukuko chofulumira cha intaneti ya Zinthu, ukadaulo wa Bluetooth wotsika mphamvu wagwiritsidwa ntchito kwambiri, ndipo ukadaulo wamagetsi otsika a Bluetooth ukungobwerezabwereza, ndipo chilichonse chatsopano ndi njira yatsopano.Lingaliro laukadaulo wocheperako wa Bluetooth ndikuti umagwiritsa ntchito mphamvu zochepa.M'malo mwake, ili ndi mfundo zazikuluzikulu zakuzizira.Tiyeni tione.
1. Bluetooth Low Energy ndiyobwerera m'mbuyo imagwirizana ndi:
Mwachitsanzo, popeza Bluetooth 5.2 yatulutsidwa, ndipo mumapanga chipangizo chomwe chimagwiritsa ntchito teknoloji ya Bluetooth 5.2, chipangizochi chikhoza kugwirizanitsa ndi zipangizo zomwe zimagwiritsa ntchito teknoloji ya Bluetooth 4.0.Pali zosiyana ndi lamuloli, makamaka ngati chimodzi mwazidazo chimagwiritsa ntchito mawonekedwe amtundu wina wa Bluetooth, koma pamachitidwe apakatikati, mawonekedwewo amatsimikizira kuti zimagwirizana.
2. Bluetooth Low Energy imatha kukwaniritsa mitundu yopitilira 1 km:
Tanthauzo lapachiyambi laukadaulo wa Bluetooth wamagetsi otsika ndi mphamvu zotsika, kufalitsa kwapang'onopang'ono.Koma njira yatsopano yotchedwa Long Range Mode (Coded PHY) idayambitsidwa mu Bluetooth 5.0, yomwe imalola zida za BLE kuti zizilankhulana pazitali zazitali, mpaka 1.5 km mzere wakuwona.
3. Ukadaulo wocheperako wa Bluetooth umathandizira ma point-to-point, nyenyezi ndi ma mesh topology:
Ukadaulo wocheperako wa Bluetooth ndi imodzi mwamaukadaulo ochepa opanda zingwe opanda mphamvu omwe amatha kutengera ma topolologies osiyanasiyana pamapulogalamu osiyanasiyana.Imathandizira kulumikizana kwa anzawo, monga pakati pa foni yamakono ndi tracker yolimbitsa thupi.Kuphatikiza apo, imathandizira ma topology amodzi mpaka ambiri, monga Bluetooth Low Energy hub yomwe imalumikizana ndi zida zingapo zapanyumba nthawi imodzi.Pomaliza, poyambitsa ma mesh a Bluetooth mu Julayi 2017, BLE imathandiziranso ma topology ambiri mpaka ambiri (ma mesh).
4. Paketi yotsatsa ya Bluetooth yotsika mphamvu imakhala ndi data yofikira ma 31:
Uwu ndiye muyeso wokhazikika wamalipiro otsatsa pamapaketi omwe amatumizidwa pamakina otsatsa (37, 38, ndi 39).Komabe, kumbukirani kuti ma byte 31 amenewo azikhala ndi ma byte osachepera awiri: imodzi yautali ndi ina yamtundu wake.Kwatsala ma byte 29 kuti agwiritse ntchito.Komanso, kumbukirani kuti ngati muli ndi magawo angapo okhala ndi mitundu yosiyanasiyana ya zotsatsa, mtundu uliwonse utenga ma byte awiri owonjezera kutalika ndi mtundu.Pamapaketi otsatsa omwe amatumizidwa panjira yachiwiri yotsatsira (yomwe idayambitsidwa mu Bluetooth 5.0), malipiro amakulitsidwa mpaka 254 byte m'malo mwa 31 byte.
