Mojule o tsoetseng pele oa moralo oa sehlahisoa sa audio o se nang mohala o thehiloeng ho Nordic Semiconductor's EA-K5340 high-end multiprotocol SoC, e thehiloe ke k'hamphani ea IoT, Shenzhen Feasycom. Mojule oa 'FSC-BT631D' o fanoa ka sephutheloana sa compact 12 by 15 by 2.2 mm, 'me o hlalosoa ke khamphani e le oa pele lefatšeng. Bluetooth® mojule o ka tšehetsang ka bobeli LE Audio le Bluetooth Classic. Ntle le nRF5340 SoC, mojule o kopanya chipset ea transceiver ea Bluetooth Classic bakeng sa ho nolofalletsa lits'ebetso tsa audio tsa Bluetooth tsa lefa.
Moloko o latelang oa audio audio
"LE Audio ke moloko o latelang oa molumo oa Bluetooth," ho bolela Nan Ouyang, CEO ho Shenzhen Feasycom. "E etsa hore molumo oa molumo ka Bluetooth LE o khonehe ka ts'ebetso e ntlafetseng ea boleng ba molumo, tšebeliso ea matla, latency, le bandwidth. Ha indasteri e ntse e fetoha ho tloha Classic Audio ho LE Audio, bahlahisi ba lihlahisoa tsa lisebelisoa tsa mohala ba hloka tharollo e ka tšehetsang liphetolelo tse peli, e leng hobaneng re thehile mojule oa FSC-BT631D."
"NRF Connect SDK le eona e ne e le ea bohlokoa ho pholletsa le ts'ebetso ea ntlafatso ea LE Audio."
Mohlala, litharollo tsa lisebelisoa tsa molumo tse sebelisang mojule oa Feasycom li ka hokela lisebelisoa tsa mohloli oa molumo joalo ka smartphone, laptop kapa TV e sebelisang Bluetooth Classic, ebe e fetisetsa molumo ho palo e sa lekanyetsoang ea lisebelisoa tse ling tsa LE Audio tse sebelisang molumo oa Auracast™.
Mojule ona o sebelisa li-processor tsa nRF5340 SoC's dual Arm® Cortex®-M33 - e fana ka processor ea ts'ebetso e phahameng e khonang ho etsa DSP le Floating Point (FP) hammoho le processor ea marang-rang e hlophisehileng ka botlalo, e tlase haholo. Sesebelisoa sa mantlha se laola ka bobeli LE Audio codec le codec bakeng sa audio ea khale ea Bluetooth, ha protocol ea Bluetooth LE e laoloa ke processor ea marang-rang.
Tšehetso bakeng sa liprothokholo tse ngata
Khokahano ea LE Audio e khoneha ka seea-le-moea sa nRF5340 SoC's 2.4 GHz multiprotocol e nang le matla a tlhahiso ea 3 dBm le -98 dBm RX sensitivity bakeng sa tekanyetso ea khokahano ea 101 dBm. Radio ena e boetse e ts'ehetsa liprothokholo tse ling tse kholo tsa RF ho kenyelletsa Bluetooth 5.3, Bluetooth Direction Finding, Long Range, Bluetooth mesh, Thread, Zigbee, le ANT™.
"Re khethile nRF5340 SoC hobane e fihletse bonngoe bo tsitsitseng ba LE Audio le Bluetooth Classic e neng e le senotlolo sa ts'ebeliso ena," ho bolela Ouyang. "Ts'ebetso ea li-CPU tse peli-core, ts'ebetso e ntle ea matla, le ts'ebetso ea RF e bile lintlha tse ling qetong."
Tšebeliso ea matla a tlase haholo e khoneha ka lebaka la seea-le-moea se secha sa nRF5340, se nang le matla a mangata, se fanang ka TX ea hona joale ea 3.4 mA (0 dBm TX matla, 3 V, DC/DC) le RX ea hona joale ea 2.7 mA (3). V, DC/DC). Nako ea ho robala e tlase ho 0.9 µA. Ho feta moo, hobane li-cores li ka sebetsa ka boikemelo, bahlahisi ba na le monyetla oa ho ntlafatsa ts'ebetso bakeng sa ts'ebeliso ea matla, ts'ebetso le karabelo e tlase ea latency.
"NRF Connect SDK le eona e bile bohlokoa haholo ts'ebetsong ea ntlafatso ea LE Audio, hammoho le tlhaiso-leseling e ntle ea tekheniki le lienjineri tsa ts'ebeliso tse fanoeng ke Nordic," ho bolela Ouyang.
