LE Audio Development History Thiab Bluetooth LE Audio Module Introduction
1. Classic Bluetooth
1) Ib qho transmitter txuas nrog ib tus txais
2) Hom suab paj nruag: A2DP, tswj los ntawm AVRCP raws tu qauv
Suab paj nruag ncua / ua si, nce thiab nqis nkauj / ntim nce thiab nqis
3) Hu rau hom: HFP (Hands-Free Profile)
Xov tooj tes-dawb raws tu qauv, teb / hang up / reject / suab dialing, thiab lwm yam.
A2DP: Tshaj Tawm Txog Cov Ntawv Xa Suab
AVRCP: Suab / Video Chaw Taws Teeb Tswj Profile
2. Bluetooth TWS #1 (True Wireless Stereo)
1) Cov txheej txheem sib kis yog tib yam li Bluetooth classic
2) Lub pob ntseg sab laug / sab xis txuas nrog lub xov tooj ntawm tes,
Lub pob ntseg sab laug lossis sab xis kuj txuas rau ib leeg, yog li lub pob ntseg yog ob qho tib si receiver (Sink) thiab transmitter (Source).
3.Bluetooth TWS#2 (Tseeb Wireless Stereo)
1) Cov txheej txheem sib kis yog tib yam li Bluetooth classic
2) Lub xov tooj ntawm tes txuas nrog rau sab laug / sab xis earphone tib lub sijhawm, thiab sab laug thiab txoj cai tau txais kev tso cai
4. Suab Full-duplex
1) Cov txheej txheem sib kis yog tib yam li Bluetooth classic
2) Txuas ob lub mloog pob ntseg tib lub sijhawm, tsis hais ntawm sab laug thiab sab xis
3) Pob ntseg 1 thiab pob ntseg 2 tuaj yeem sib tham
4) Module pom zoo: BT901, BT906, BT936B, wb 1036b thiab lwm yam
5. Bluetooth LE AUDIO
1) Tshaj tawm muaj nuj nqi: lub xov tooj ntawm tes tuaj yeem txuas tau ntau yam Bluetooth cov khoom siv tib lub sijhawm, suav nrog Bluetooth headsets, lub mloog pob ntseg thiab lwm yam.
2) Kev sib koom ua haujlwm: kev sib txuas ntau tus neeg
3) Kev sib txuas ntau yam, xws li xov tooj ntawm tes, ipad, khoos phis tawj, thiab lwm yam tib lub sijhawm
4) Khiav ntawm Bluetooth qis zog tshuab
5) High-quality, high-speed kis tau tus mob-LC3 encoding
6) Tsawg latency (tsawg kawg 20ms, txog 1-200ms hauv qab Bluetooth 5.1)
7) Bluetooth version 5.2 lossis siab dua
6. LE AUDIO-LC3
1) LC3 (Low Complexity Communications Codec) cov kev qhia tshwj xeeb tau raug tso tawm los ntawm Bluetooth SIG thaum lub Cuaj Hlis 15, 2020. Txhua lub suab profile (Profiles) ntawm LE Audio yuav raug yuam kom siv LC3 suab codec ntaus ntawv.
2) Kev sib piv tus nqi sib piv ntawm LC3 thiab SBC yog raws li hauv qab no
