Babban samfuri don ƙira samfurin sauti mara waya bisa na Nordic Semiconductor's nFF5340 babban-karshen multiprotocol SoC, an ƙaddamar da shi ta kamfanin IoT, Shenzhen Feasycom. Ana ba da samfurin 'FSC-BT631D' a cikin ƙaramin kunshin 12 zuwa 15 ta 2.2 mm, kuma kamfanin ya bayyana shi a matsayin farkon duniya. Bluetooth® module wanda zai iya tallafawa duka biyun Le Audio da kuma Bluetooth Classic. Bugu da ƙari ga nRF5340 SoC, ƙirar tana haɗe da kwakwalwan kwamfuta na Bluetooth Classic transceiver don ba da damar gadon aikace-aikacen sauti na Bluetooth.
Ƙarni na gaba na sauti mara waya
"LE Audio shine ƙarni na gaba na sauti na Bluetooth," in ji Nan Ouyang, Shugaba a Shenzhen Feasycom. "Yana sa sauti mai jiwuwa akan Bluetooth LE ya yiwu tare da ingantaccen aiki a cikin ingancin sauti, amfani da wutar lantarki, latency, da bandwidth. Yayin da masana'antar ke canzawa daga Classic Audio zuwa LE Audio, masu haɓaka samfuran sauti mara waya suna buƙatar mafita wanda zai iya tallafawa nau'ikan biyu, wanda shine. dalilin da ya sa muka haɓaka FSC-BT631D module."
"NRF Connect SDK shima yana da matukar amfani a duk tsarin ci gaban LE Audio."
Misali, mafita kayan aikin jiwuwa da ke amfani da tsarin Feasycom na iya haɗawa zuwa na'urorin tushen mai jiwuwa kamar wayoyi, kwamfutar tafi-da-gidanka ko TV ta amfani da Bluetooth Classic, sannan watsa sauti zuwa adadi mara iyaka na sauran na'urorin LE Audio ta amfani da Auracast™ watsa sauti.
Tsarin yana ɗaukar nRF5340 SoC's dual Arm® Cortex®-M33 na'urori masu sarrafawa - yana ba da babban na'ura mai sarrafa kayan aiki mai ƙarfi na DSP da Floating Point (FP) tare da cikakkiyar na'ura mai sarrafa shirye-shirye, ultra low power processor. Babban aikace-aikacen yana sarrafa duka LE Audio codec da codec don sauti na Bluetooth na al'ada, yayin da ƙa'idar Bluetooth LE ke kula da mai sarrafa hanyar sadarwa.
Taimako don ƙa'idodi masu yawa
Haɗin LE Audio yana yiwuwa ta hanyar nRF5340 SoC's 2.4 GHz rediyo multiprotocol mai nuna ƙarfin fitarwa 3 dBm da -98 dBm RX hankali don tsarin haɗin gwiwa na 101 dBm. Wannan rediyon kuma yana goyan bayan wasu manyan ka'idojin RF da suka haɗa da Bluetooth 5.3, Neman Hanyar Bluetooth, Dogon Range, ragar Bluetooth, Zare, Zigbee, da ANT™.
"Mun zaɓi nRF5340 SoC saboda ya sami kwanciyar hankali na LE Audio da Bluetooth Classic wanda shine mabuɗin wannan aikace-aikacen," in ji Ouyang. "Ayyukan CPUs dual-core, ingantaccen ƙarfin wutar lantarki, da aikin RF sune wasu dalilai a cikin shawarar."
An sami damar yin amfani da ƙananan ƙarancin wutar lantarki saboda sabon nRF5340, ingantaccen rediyo mai ƙarfi da yawa, wanda ke ba da TX na yanzu na 3.4 mA (ikon 0 dBm TX, 3 V, DC/DC) da RX na yanzu na 2.7 mA (3) V, DC / DC). A halin yanzu barci yana da ƙasa da 0.9 µA. Bugu da ƙari, saboda muryoyin na iya yin aiki da kansu, masu haɓakawa suna da sassauci don haɓaka aiki don amfani da wutar lantarki, fitarwa, da ƙarancin jinkiri.
"NRF Connect SDK shima yana da kima a duk cikin tsarin ci gaban LE Audio, tare da ingantattun bayanan fasaha da injiniyoyin aikace-aikacen da Nordic suka samar," in ji Ouyang.
