Imojula ethuthukisiwe yomklamo womkhiqizo womsindo ongenazintambo esekelwe ku-Nordic Semiconductor's Imvu high-end multiprotocol SoC, yethulwe yinkampani ye-IoT, i-Shenzhen Feasycom. Imojula ye-'FSC-BT631D' ihlinzekwa ngephakheji eyi-compact 12 by 15 by 2.2 mm, futhi ichazwa inkampani njengeyokuqala emhlabeni. Bluetooth® imojuli ekwazi ukusekela kokubili LE Audio kanye ne-Bluetooth Classic. Ngokungeziwe ku-nRF5340 SoC, imojula ihlanganisa i-chipset ye-Bluetooth Classic transceiver ukuze inike amandla izinhlelo zokusebenza zomsindo we-Bluetooth zefa.
Isizukulwane esilandelayo somsindo ongenantambo
"I-LE Audio iyisizukulwane esilandelayo somsindo we-Bluetooth," kusho uNan Ouyang, oyi-CEO kwa-Shenzhen Feasycom. "Yenza ukusakazwa komsindo nge-Bluetooth LE kwenzeke ngokusebenza okuthuthukisiwe kwekhwalithi yomsindo, ukusetshenziswa kwamandla, ukubambezeleka, kanye nomkhawulokudonsa. Njengoba imboni ishintsha isuka ku-Classic Audio iye ku-LE Audio, abathuthukisi bomkhiqizo womsindo ongenazintambo badinga isisombululo esingakwazi ukusekela zombili izinguqulo, okungukuthi kungani sithuthukise imojuli ye-FSC-BT631D."
"I-nRF Connect SDK nayo yaba wusizo kuyo yonke inqubo ye-LE Audio yokuthuthukisa."
Isibonelo, izixazululo zemishini yomsindo ezisebenzisa imojuli ye-Feasycom zingaxhumeka kumadivayisi omthombo womsindo njenge-smartphone, ikhompuyutha ephathekayo noma i-TV isebenzisa i-Bluetooth Classic, bese idlulisela umsindo enanini elingenamkhawulo lamanye amadivayisi we-LE Audio kusetshenziswa umsindo wokusakaza we-Auracast™.
Imojula isebenzisa ama-nRF5340 SoC's dual Arm® Cortex®-M33 processors – ehlinzeka ngephrosesa yohlelo lokusebenza oluphezulu olukwazi i-DSP ne-Floating Point (FP) eduze kwephrosesa yenethiwekhi enamandla aphansi ehlelekayo ngokugcwele. Umongo wohlelo lokusebenza ulawula kokubili i-LE Audio codec kanye nekhodekhi yomsindo we-Bluetooth yakudala, kuyilapho iphrothokholi ye-Bluetooth LE igadwe iphrosesa yenethiwekhi.
Usekelo lwamaphrothokholi amaningi
Uxhumano lwe-LE Audio lwenziwa lwaba nokwenzeka ngomsakazo we-nRF5340 SoC's 2.4 GHz multiprotocol enamandla okukhipha angu-3 dBm kanye nokuzwela -98 dBm RX ngesabelomali sesixhumanisi esingu-101 dBm. Lo msakazo futhi usekela ezinye izimiso ze-RF ezinkulu ezihlanganisa i-Bluetooth 5.3, i-Bluetooth Direction Finding, i-Long Range, i-Bluetooth mesh, i-Thread, i-Zigbee, ne-ANT™.
"Sikhethe i-nRF5340 SoC ngoba ithole ukuphilisana okuzinzile kwe-LE Audio ne-Bluetooth Classic obekubalulekile kulolu hlelo lokusebenza," kusho u-Ouyang. "Ukusebenza kwe-dual-core CPUs, ukusebenza kahle kwamandla okuhle kakhulu, nokusebenza kwe-RF kube ezinye izici esinqumweni."
Ukusetshenziswa kwamandla okuphansi kakhulu kwenziwa kwaba nokwenzeka ngenxa yomsakazo omusha we-nRF5340, owenziwe ngamandla we-multiprotocol, ohlinzeka nge-TX yamanje engu-3.4 mA (0 dBm TX amandla, 3 V, DC/DC) kanye ne-RX yamanje engu-2.7 mA (3 V, DC/DC). Isikhathi sokulala siphansi njengo-0.9 µA. Ukwengeza, ngenxa yokuthi ama-cores angasebenza ngokuzimela, abathuthukisi banokuguquguquka kokuthuthukisa ukusebenza kokusetshenziswa kwamandla, ukuphuma, kanye nokusabela okuphansi kwe-latency.
"I-nRF Connect SDK iphinde yaba wusizo kulo lonke uhlelo lokuthuthukiswa kwe-LE Audio, kanye nolwazi oluhle kakhulu lwezobuchwepheshe kanye nonjiniyela bezinhlelo zokusebenza abahlinzekwe ngabakwaNordic," kusho u-Ouyang.
