Modul dị elu maka imepụta ngwaahịa ọdịyo ikuku dabere na Nordic Semiconductor's NJ5340 SoC multiprotocol dị elu, bụ ụlọ ọrụ IoT, Shenzhen Feasycom ewepụtala ya. A na-enye modul 'FSC-BT631D' na ngwugwu 12 site na 15 site na 2.2 mm, ụlọ ọrụ ahụ kọwara ya dị ka nke mbụ n'ụwa. Bluetooth® modul nke nwere ike ịkwado ha abụọ LE Audio na Bluetooth Classic. Na mgbakwunye na nRF5340 SoC, modul ahụ na-ejikọta chipset transceiver Bluetooth Classic maka inye ngwa ọdịyo Bluetooth ike.
Ọgbọ na-esote nke ọdịyo ikuku
"LE Audio bụ ọgbọ na-esote nke ọdịyo Bluetooth," Nan Ouyang, CEO na Shenzhen Feasycom kwuru. "Ọ na-eme ka mgbasa ozi ọdịyo n'elu Bluetooth LE kwe omume site na arụmọrụ dị elu na ogo ụda, ike oriri, latency, na bandwit. Ka ụlọ ọrụ na-agbanwe site na Classic Audio gaa na LE Audio, ndị na-emepụta ngwaahịa ọdịyo ikuku chọrọ ngwọta nke nwere ike ịkwado nsụgharị abụọ ahụ, nke bụ. ihe mere anyị ji mepụta modul FSC-BT631D."
"NRF Jikọọ SDK bụkwa ihe bara uru n'oge usoro mmepe LE Audio."
Dịka ọmụmaatụ, ngwọta akụrụngwa ọdịyo na-eji Feasycom modul nwere ike jikọọ na ngwaọrụ isi iyi dị ka smartphone, laptọọpụ ma ọ bụ TV site na iji Bluetooth Classic, wee bufee ọdịyo na ọnụ ọgụgụ na-akparaghị ókè nke ngwaọrụ LE Audio ndị ọzọ site na iji Auracast™ mgbasa ozi ọdịyo.
Modul ahụ na-eji nRF5340 SoC's dual Arm® Cortex®-M33 processors - na-enye ihe nrụpụta ngwa arụmọrụ dị elu nwere ike nke DSP na Floating Point (FP) n'akụkụ ihe nrụpụta netwọkụ zuru oke, nke nwere ike dị ala. Isi ngwa a na-ejikwa ma LE Audio codec na codec maka ọdịyo Bluetooth kpochapụwo, ebe onye nrụpụta netwọk na-ahụ maka ụkpụrụ Bluetooth LE.
Nkwado maka otutu protocol
A na-eme ka njikọta LE Audio kwe omume site na nRF5340 SoC's 2.4 GHz multiprotocol redio na-egosipụta ike mmepụta 3 dBm na -98 dBm RX uche maka mmefu ego njikọ nke 101 dBm. Redio a na-akwadokwa ụkpụrụ RF ndị ọzọ bụ isi gụnyere Bluetooth 5.3, Nchọta ntụzịaka Bluetooth, Ogologo ogologo, ntupu Bluetooth, eriri, Zigbee na ANT™.
"Anyị họrọ nRF5340 SoC n'ihi na ọ nwetara ịdị n'otu nke LE Audio na Bluetooth Classic nke bụ isi na ngwa a," Ouyang kwuru. "Arụmọrụ nke CPUs dual-core, ezigbo ike ịrụ ọrụ, na arụmọrụ RF bụ ihe ndị ọzọ na mkpebi ahụ."
Emere ka oriri ike dị ala dị ala kwe omume n'ihi nRF5340 ọhụrụ, redio multiprotocol kwadoro ike, nke na-enye TX ugbu a nke 3.4 mA (0 dBm TX ike, 3 V, DC / DC) na RX ugbu a nke 2.7 mA (3). V, DC / DC). Oge ihi ụra dị ntakịrị ka 0.9 µA. Na mgbakwunye, n'ihi na cores nwere ike ịrụ ọrụ n'onwe ya, ndị mmepe nwere ike imeziwanye arụmọrụ maka oriri ike, ntinye, na nzaghachi nkwụsịtụ dị ala.
Ouyang kwuru, "NRF Jikọọ SDK dịkwa oke ọnụ ahịa n'oge usoro mmepe LE Audio niile, yana ezigbo ozi teknụzụ na ndị injinia ngwa nke Nordic nyere," Ouyang kwuru.
