ʻO kahi module holomua no ka hoʻolālā huahana leo uila e pili ana i ka Nordic Semiconductor's NRF5340 ʻO SoC multiprotocol kiʻekiʻe, ua hoʻokumu ʻia e ka hui IoT, ʻo Shenzhen Feasycom. Hāʻawi ʻia ka module 'FSC-BT631D' i kahi pūʻolo 12 me 15 me 2.2 mm paʻa, a ua wehewehe ʻia e ka hui ʻo ia ka mea mua o ka honua. Bluetooth® module hiki ke kākoʻo i nā mea ʻelua LE Audio a me Bluetooth Classic. Ma waho aʻe o ka nRF5340 SoC, hoʻohui ka module i kahi Bluetooth Classic transceiver chipset no ka hiki ʻana i nā noi leo Bluetooth hoʻoilina.
ʻO ka hanauna e hiki mai ana o ka leo uila
"ʻO LE Audio ka hanauna hou o ka leo Bluetooth," wahi a Nan Ouyang, Luna Nui ma Shenzhen Feasycom. "E hiki ai ke hoʻoheheʻe leo leo ma luna o Bluetooth LE me ka hoʻonui ʻana i ka hana i ka maikaʻi o ke kani, ka hoʻohana ʻana i ka mana, latency, a me ka bandwidth. I ka hoʻololi ʻana o ka ʻoihana mai Classic Audio a i LE Audio, pono nā mea hoʻomohala huahana leo uila i kahi hopena e hiki ke kākoʻo i nā mana ʻelua, ʻo ia hoʻi. no ke aha mākou i kūkulu ai i ka module FSC-BT631D."
"He mea waiwai nui ka nRF Connect SDK ma ke kaʻina hana hoʻomohala LE Audio."
No ka laʻana, hiki i nā hāmeʻa leo leo e hoʻohana ana i ka module Feasycom ke hoʻopili i nā polokalamu kumu leo e like me ke kelepona, kamepiula a TV paha me ka Bluetooth Classic, a laila e hoʻouna i ka leo i kahi helu palena ʻole o nā mea LE Audio ʻē aʻe me ka hoʻohana ʻana i ka leo hoʻolaha Auracast™.
Hoʻohana ka module i nā mea hana ʻelua Arm® Cortex®-M5340 o nRF33 SoC - e hāʻawi ana i kahi kaʻina noi hana kiʻekiʻe hiki ke DSP a me ka Floating Point (FP) ma ka ʻaoʻao o kahi mea hoʻohana pūnaewele piha loa. Na ke kumu noi e hoʻokele i ka LE Audio codec a me ka codec no ka leo Bluetooth maʻamau, ʻoiai ke kiaʻi ʻia ka protocol LE Bluetooth e ka mea hana pūnaewele.
Kākoʻo no nā protocol he nui
Hiki ke hoʻohui ʻia ka LE Audio ma o ka nRF5340 SoC's 2.4 GHz multiprotocol radio e hōʻike ana i ka mana hoʻopuka 3 dBm a me -98 dBm RX sensitivity no kahi waihona loulou o 101 dBm. Kākoʻo pū kēia lekiō i nā protocol RF nui ʻē aʻe me Bluetooth 5.3, Bluetooth Direction Finding, Long Range, Bluetooth mesh, Thread, Zigbee, a me ANT™.
"Ua koho mākou i ka nRF5340 SoC no ka mea ua hoʻokō i kahi noho paʻa o LE Audio a me Bluetooth Classic ka mea nui i kēia noi," wahi a Ouyang. "ʻO ka hana o nā CPU dual-core, ka mana maikaʻi loa, a me ka hana RF ʻo ia nā kumu ʻē aʻe i ka hoʻoholo."
Hiki ke hoʻohana ʻia ka mana ultra-haʻahaʻa ma muli o ka nRF5340 hou, mana-optimized multiprotocol radio, e hāʻawi ana i kahi manawa TX o 3.4 mA (0 dBm TX mana, 3 V, DC/DC) a me RX o kēia manawa o 2.7 mA (3. V, DC/DC). ʻO ka haʻahaʻa o ka moe moe he 0.9 µA. Eia hou, no ka mea hiki i nā cores ke hana kūʻokoʻa, hiki i nā mea hoʻomohala ke hiki ke hoʻonui i ka hana no ka hoʻohana ʻana i ka mana, throughput, a me ka pane latency haʻahaʻa.
"He waiwai nui ka nRF Connect SDK i loko o ke kaʻina hana hoʻomohala LE Audio, me ka ʻike ʻenehana maikaʻi loa a me nā ʻenekini noi i hāʻawi ʻia e Nordic," wahi a Ouyang.
NO KA MEA Hoʻomaʻamaʻa ʻia ka module Nordic-powered i ka hoʻomohala huahana Bluetooth LE Audio
