Kwakabva Bluetooth
Iyo tekinoroji yeBluetooth yakagadzirwa nekambani yeNokia muna 1994, makore mashoma gare gare, Ericsson yakapa uye yakaitiswa kuumba mubatanidzwa weBluetooth indasitiri, iyo Bluetooth Special Interest Group (SIG). Kuedza kweBluetooth SIG nenhengo dzayo kwakawedzera kukurumidza kuvandudza tekinoroji yeBluetooth.
Sekutanga kutaurwa kweBluetooth, Bluetooth 1.0 yakaburitswa muna 1999, nguva yekutanga yegore iro, yekutanga mutengi Bluetooth mudziyo wakatangwa, yaive isina-yemaoko headset, yakatanga rwendo rwekuwanikwa kweBluetooth odhiyo uye yakaratidzawo kukosha kusingadzoreki kweBluetooth. odhiyo muBluetooth ficha seti. Pindura uye fona, fax uye kufambisa faira ndezvimwe zvezvinhu zvinogona kupihwa neBluetooth 1.0, asi kutamba kwemimhanzi pamusoro peBluetooth yanga isiri sarudzo ipapo, chimwe chezvikonzero zvakakosha ndechekuti maprofile haana kugadzirira.
Chii chinonzi HSP/HFP/A2DP
Kutevera kukwidziridzwa kweBluetooth musimboti yakatarwa, iyo Bluetooth SIG yakaburitsawo mamwe akakosha anoenderana-ane maodhiyo profiles:
- Headset Profile (HSP) , inopa tsigiro yenzira mbiri odhiyo pamusoro peSsynchronous Connection Oriented link (SCO), zvikumbiro zvakaita sekuita nharembozha uye mitambo yemitambo zvinoratidzwa. Yakatanga kuburitswa muna 2001.
- Nhoroondo Yemahara Yemaoko (HFP) , ichipa rutsigiro rwenzira mbiri-odhiyo pamusoro peSsynchronous Connection Oriented link (SCO), maapplication akaita semu-mota odhiyo anoratidzwa zvakanaka. Yakatanga kuburitswa muna 2003.
- Yepamusoro Audio Distribution Profile (A2DP) , ichipa rutsigiro rweimwe-nzira yemhando yepamusoro odhiyo pamusoro peYakawedzerwa Synchronous Connection Oriented link (eSCO), kutakura data rakawanda rine bandwidth shoma, SBC codec inopihwa muA2DP mbiri, zvikumbiro senge isina waya mimhanzi inoridzwa inoratidzwa zvakanaka. Yakatanga kuburitswa muna 2003.
Bluetooth Audio nguva yakatarwa
Kungofanana neiyo Bluetooth musimboti yakatarwa, kugadzirisa matambudziko nekuvandudza zviitiko, Bluetooth odhiyo profiles zvakare yaive neimwe vhezheni yekuvandudza kubva payakazvarwa, Kugadzirwa kweasingaverengeke eBluetooth odhiyo yevatengi zvemagetsi inoshandisa maodhiyo profiles inotaura nyaya ine mukurumbira yeBluetooth odhiyo, inotevera nguva yezvimwe zviitiko zvakakosha zvemusika nezve Bluetooth odhiyo:
- 2002: Audi yakaratidza yayo nyowani A8 yaive yekutanga mota modhi iyo inogona kupa Bluetooth audio mu-mota ruzivo.
- 2004: Sony DR-BT20NX yakarova masherufu, yaive yekutanga Bluetooth mahedhifoni inokwanisa kuridza mimhanzi. Mugore rimwe chetero, Toyota Prius yakadya kumusika uye yakave yekutanga modhi yemotokari inopa Bluetooth mimhanzi yekutamba.
- 2016: Apple yakatanga AirPods Bluetooth Yechokwadi Wireless Stereo (TWS) mahedhifoni, yakaunza yakanyanya kunaka Bluetooth TWS ruzivo kune vashandisi uye yakagadzirira zvakanyanya musika weBluetooth TWS.
Iyo Bluetooth SIG yakazivisa inokatyamadza inoenderana neadhiyo uye yakaunza LE odhiyo kupasi rose paCES 2020. LC3 codec, multi-stream, Auracast nhepfenyuro yekuteerera uye rubatsiro rwekunzwa rutsigiro ndizvo zvinhu zvinouraya zvinopihwa LE odhiyo, ikozvino nyika yeBluetooth. kuvandudza nezvose zviri zviviri zvekirasi odhiyo uye LE odhiyo, kwemakore anouya, zvakafanira kutarisira kune yakawanda uye inoshamisa Bluetooth odhiyo yemagetsi.
