Nekukurumidza kusimudzira kweInternet yezvinhu, tekinoroji yeBluetooth yakaderera simba yakashandiswa zvakanyanya, uye tekinoroji yeBluetooth yakaderera inogara ichidzokororwa, uye imwe neimwe innovation inzira nyowani.Maonero eiyo yakaderera-simba Bluetooth tekinoroji ndeyekuti ine yakaderera simba rekushandisa.Muchokwadi, ichine mamwe akakosha ekuziva anotonhora mapoinzi.Ngatitarisei.
1. Bluetooth Low Energy iri kumashure inoenderana ne:
Semuenzaniso, ikozvino Bluetooth 5.2 yakaburitswa, uye iwe unogadzira mudziyo unoshandisa Bluetooth 5.2 tekinoroji, mudziyo unogona kudyidzana nemidziyo inoshandisa tekinoroji yeBluetooth 4.0.Pane zvisizvo kumutemo uyu, kunyanya kana chimwe chezvishandiso chichishandisa sarudzo dzeimwe vhezheni yeBluetooth, asi pakushanda kwepakati, iyo yakatarwa inovimbisa kuseri kunoenderana.
2. Bluetooth Low Energy inogona kuwana huwandu hweanopfuura 1 km:
Tsanangudzo yepakutanga yeiyo yakaderera-simba Bluetooth tekinoroji zvechokwadi yakaderera-simba, pfupi-renji kutapurirana.Asi imwe modhi itsva inodaidzwa kuti Long Range Mode (Coded PHY) yakaunzwa muBluetooth 5.0, iyo inobvumira michina yeBLE kutaura pamusoro pemarefu akareba, kusvika 1.5 km mutsara-wekuona.
3. Bluetooth yakaderera simba tekinoroji inotsigira point-to-point, nyeredzi uye mesh topology:
Bluetooth yakaderera simba tekinoroji ndeimwe yeashoma-simba asina waya tekinoroji anogona kugarisa akasiyana siyana epamusoro kune akawanda akasiyana maapplication.Iyo natively inotsigira kutaurirana kwevezera-kune-vezera, senge pakati peiyo smartphone uye yekusimba tracker.Pamusoro pezvo, inotsigira imwe-kune-yakawanda topology, senge Bluetooth Low Energy hub inopindirana neakawanda smart midziyo yemumba panguva imwe chete.Chekupedzisira, nekuunzwa kweiyo Bluetooth mesh yakatarwa muna Chikunguru 2017, BLE inotsigirawo akawanda-kune-akawanda topology (mesh).
4. The Bluetooth low energy advertising packet ine kusvika ku31 bytes yedata:
Iyi ndiyo saizi yakajairwa yemubhadharo wekushambadzira wemapaketi anotumirwa pamatanho ekutanga ekushambadzira (37, 38, uye 39).Zvisinei, ramba uchifunga kuti aya 31 bytes achabatanidza mabhayiti maviri: imwe yehurefu uye imwe yemhando.Kwasara 29 bytes yedata remushandisi.Zvakare, ramba uchifunga kuti kana uine akawanda minda ane akasiyana ad data mhando, yega yega inotora maviri ekuwedzera mabyte pakureba uye mhando.Pamapakiti ekushambadzira anotumirwa pachiteshi chechipiri chekushambadzira (akaunzwa muBluetooth 5.0), mubhadharo unowedzerwa kusvika ku254 bytes pachinzvimbo che31 bytes.
