Umsuka we-Bluetooth
Ubuchwepheshe be-Bluetooth basungulwa yinkampani yakwa-Ericsson ngo-1994, eminyakeni embalwa kamuva, u-Ericsson wanikela ngabo futhi waqhutshwa ukwakha umfelandawonye wemboni ye-Bluetooth, i-Bluetooth Special Interest Group (SIG). Imizamo ye-Bluetooth SIG namalungu ayo isheshise kakhulu ukuthuthukiswa kobuchwepheshe be-Bluetooth.
Njengokucaciswa kokuqala kwe-Bluetooth, i-Bluetooth 1.0 yakhululwa ngo-1999, ekuqaleni kwalowo nyaka, kwasungulwa idivayisi yokuqala ye-Bluetooth yomthengi, kwakuyi-headset engenazandla, yaqala uhambo lokutholwa komsindo we-Bluetooth futhi yaveza nokubaluleka okungenakushintshwa kwe-Bluetooth. umsindo kusethi yesici se-Bluetooth. Phendula futhi ushaye izingcingo, ifeksi kanye nokudlulisa ifayela ngezinye zezici ezinganikezwa yi-Bluetooth 1.0, kodwa ukudlalwa komculo nge-Bluetooth kwakungeyona inketho ngaleso sikhathi, esinye sezizathu ezibalulekile ukuthi amaphrofayili awalungile.
Iyini i-HSP/HFP/A2DP
Ukulandela ukuthuthukiswa kokucaciswa kwe-Bluetooth core, i-Bluetooth SIG iphinde yakhipha amaphrofayili abaluleke kakhulu ahlobene nomsindo:
- Iphrofayela ye-Headset (HSP) , ehlinzeka ngosekelo lomsindo wezindlela ezimbili ngesixhumanisi Esiku-Synchronous Connection Oriented (SCO), izinhlelo zokusebenza ezifana nokwenza izingcingo namakhonsoli amageyimu zifakwe kahle. Iqale ukukhishwa ngo-2001.
- Iphrofayela Yezandla Ezingenazandla (HFP) , ehlinzeka ngosekelo lomsindo wezindlela ezimbili ngesixhumanisi Esiqondiswe Ekuxhumaneni Okuvumelanayo (SCO), izinhlelo zokusebenza ezinjengomsindo ongaphakathi emotweni zifakwe kahle. Iqale ukukhishwa ngo-2003.
- Iphrofayela Ethuthukisiwe Yokusabalalisa Umsindo (A2DP) , ehlinzeka ngokusekela komsindo wendlela eyodwa wekhwalithi ephezulu ngesixhumanisi Esiku-Extended Synchronous Connection Oriented (eSCO), ukuthwala idatha yomsindo eyengeziwe enomkhawulokudonsa olinganiselwe, i-codec ye-SBC igunyazwe kuphrofayela ye-A2DP, izinhlelo zokusebenza ezifana nokudlalwa komculo okungenantambo kufakwe kahle. Iqale ukukhishwa ngo-2003.
Umugqa wesikhathi we-Bluetooth Audio
Njengokucaciswa kwe-Bluetooth core, ukuxazulula izinkinga kanye nokwenza ngcono okuhlangenwe nakho, amaphrofayili omsindo we-Bluetooth nawo abe nezibuyekezo zenguqulo kusukela azalwa, Ukwakhiwa kwenqwaba yama-electronics e-Bluetooth alalelwayo asebenzisa amaphrofayili alalelwayo kulandisa indaba edumile yomsindo we-Bluetooth, okulandelayo umugqa wesikhathi wemicimbi ethile yemakethe ebalulekile mayelana nomsindo we-Bluetooth:
- 2002: Abakwa-Audi baveze i-A8 yabo entsha sha okube yimodeli yemoto yokuqala ekwazi ukuhlinzeka ngomsindo we-Bluetooth emotweni.
- 2004: I-Sony DR-BT20NX ishaye amashalofu, bekuyi-headphone yokuqala ye-Bluetooth ekwazi ukudlala umculo. Ngawo lowo nyaka, i-Toyota Prius yadla isidlo sasemini emakethe futhi yaba imodeli yemoto yokuqala enikeza umuzwa wokudlala umculo we-Bluetooth.
- 2016: I-Apple yethule ama-earbud e-AirPods Bluetooth True Wireless Stereo (TWS), ilethe umuzwa ongcono kakhulu we-Bluetooth TWS kubasebenzisi futhi yalungiselela ngokuphawulekayo imakethe ye-Bluetooth TWS.
I-Bluetooth SIG imemezele isibuyekezo esisha esihlobene nomsindo futhi yethula umsindo we-LE emhlabeni wonke ngo-CES 2020. I-LC3 codec, ukusakaza okuningi, i-Auracast yokusakaza umsindo nokusekelwa kwensiza yokuzwa yizici ezibulalayo ezinikezwa ngumsindo we-LE, manje umhlaba we-Bluetooth ukuthuthukiswa ngakho kokubili okulalelwayo kwakudala kanye nomsindo we-LE, eminyakeni ezayo, kufanelekile ukubheka phambili kokumangalisa ngokwengeziwe komsindo we-Bluetooth kagesi.
