Mbiri ya LE Audio Development ndi Bluetooth LE Audio Module Introduction
1. Classic Bluetooth
1) Transmitter imodzi yolumikizidwa ndi wolandila m'modzi
2) Mtundu wanyimbo: A2DP, yoyendetsedwa ndi protocol ya AVRCP
Imitsani nyimbo / kusewera, nyimbo yokwera ndi pansi / voliyumu yokwera ndi pansi
3) Mawonekedwe Oyimbira: HFP (Mtundu Wopanda Mmanja)
Pulogalamu ya foni yopanda manja, yankhani / lembani / kanani / kuyimba ndi mawu, ndi zina.
A2DP: Mbiri Yapamwamba Yogawa Nyimbo
AVRCP: Mbiri Yakutali Yomvera / Kanema
2. Bluetooth TWS#1 (True Wireless Stereo)
1) Protocol yotumizira ndi yofanana ndi Bluetooth yapamwamba
2) Chimakutu chakumanzere / kumanja chimalumikizidwa ndi foni yam'manja,
Zomvera m'makutu zakumanzere kapena kumanja zimalumikizidwanso wina ndi mzake, kotero zomvera m'makutu zonse ndi zolandila (Sink) ndi transmitter (Source).
3. bulutufi TWS#2 (True Wireless Stereo)
1) Protocol yotumizira ndi yofanana ndi Bluetooth yapamwamba
2) Foni yam'manja imalumikizidwa ndi m'makutu wakumanzere / kumanja nthawi yomweyo, ndipo njira zakumanzere ndi zakumanja zimaperekedwa zokha.
4. Audio Full-duplex
1) Protocol yotumizira ndi yofanana ndi Bluetooth yapamwamba
2）Lumikizani mahedifoni awiri nthawi imodzi, mosasamala kanthu za kumanzere ndi kumanja
3）Zomvera m’makutu 1 ndi m’makutu 2 zimatha kulankhulana
4）Module amavomereza: BT901, BT906, BT936B, Mtengo wa BT1036B etc.
5. Bluetooth LE AUDIO
1) Ntchito yowulutsa: foni yam'manja imatha kulumikiza angapo Bluetooth zida nthawi yomweyo, kuphatikiza mahedifoni a Bluetooth, zothandizira kumva ndi zina.
2) Ntchito yogawana: kulumikizana kwa anthu ambiri
3) Kulumikizana kwazinthu zambiri, monga foni yam'manja, ipad, kompyuta, ndi zina zambiri nthawi yomweyo
4) Imayendera ukadaulo wa Bluetooth low energy
5）Kutumiza kwapamwamba, kothamanga kwambiri—LC3 encoding
6) Low latency (osachepera 20ms, pafupifupi 1-200ms pansi pa Bluetooth 5.1)
7) Mtundu wa Bluetooth 5.2 kapena kupitilira apo
6. LE AUDIO–LC3
1) Mafotokozedwe aukadaulo a LC3 (Low Complexity Communications Codec) adatulutsidwa mwalamulo ndi Bluetooth SIG pa Seputembara 15, 2020. Mbiri zonse zomvera (Profile) za LE Audio adzakakamizika kugwiritsa ntchito LC3 audio codec chipangizo.
2）Kuyerekeza kwapakati pa LC3 ndi SBC kuli motere
