Iyo yepamusoro module yewireless odhiyo chigadzirwa dhizaini yakavakirwa paNordic Semiconductor's nRF5340 high-end multiprotocol SoC, yakatangwa nekambani yeIoT, Shenzhen Feasycom. Iyo 'FSC-BT631D' module inopihwa mune compact 12 ne15 ne2.2 mm package, uye inotsanangurwa nekambani seyekutanga pasirese. MAKARALI USB® module inogona kutsigira ese ari maviri LE Audio uye Bluetooth Classic. Pamusoro peiyo nRF5340 SoC, iyo module inobatanidza Bluetooth Classic transceiver chipset yekugonesa legacy Bluetooth audio application.
Chizvarwa chinotevera chewireless audio
"LE Audio ndicho chizvarwa chinotevera cheBluetooth audio," anodaro Nan Ouyang, CEO kuShenzhen Feasycom. "Inoita kuti ruzha rwekutenderera pamusoro peBluetooth LE zvigoneke nekuwedzerwa kushanda mumhando yekurira, kushandiswa kwesimba, latency, uye bandwidth. Sezvo indasitiri inoshanduka kubva kuClass Audio kuenda ku LE Audio, vagadziri vezvigadzirwa zvewireless vanoda mhinduro inogona kutsigira shanduro mbiri, iyo sei isu takagadzira iyo FSC-BT631D module."
"NRF Batanidza SDK yakakoshawo mukati me LE Audio yekuvandudza maitiro."
Semuyenzaniso, maodhiyo emidziyo mhinduro inoshandisa Feasycom module inogona kubatanidza kune odhiyo sosi zvishandiso senge smartphone, laptop kana TV ichishandisa Bluetooth Classic, yobva yaendesa odhiyo kune isina muganho wemamwe maLE Audio zvishandiso uchishandisa Auracast ™ nhepfenyuro odhiyo.
Iyo module inoshandisa nRF5340 SoC's dual Arm® Cortex®-M33 processors - ichipa yakakwirira performance application processor inokwanisa DSP uye Floating Point (FP) padivi peinorongeka zvizere, yekupedzisira yakaderera simba network processor. Iyo yakakosha yekushandisa inokwenenzvera ese LE Audio codec uye iyo codec yekirasi Bluetooth odhiyo, nepo Bluetooth LE protocol inotungamirwa netiweki processor.
Tsigiro yemaprotocol akawanda
Iyo LE Audio yekubatanidza inogoneka kuburikidza nenRF5340 SoC's 2.4 GHz multiprotocol radio ine 3 dBm yekubuda simba uye -98 dBm RX senitivity yekubatanidza bhajeti ye101 dBm. Iyi nhepfenyuro inotsigirawo mamwe makuru eRF mapuroteni anosanganisira Bluetooth 5.3, Bluetooth Direction Kutsvaga, Yakareba Range, Bluetooth mesh, Thread, Zigbee, uye ANT™.
"Takasarudza iyo nRF5340 SoC nekuti yakawana kugarisana kwakagadzikana kweLE Audio uye Bluetooth Classic yaive kiyi pakushandisa uku," anodaro Ouyang. "Kuita kweaviri-musimboti CPUs, kugona kwakanyanya kwesimba, uye kuita kweRF zvaive zvimwe zvinhu musarudzo."
Iyo yekupedzisira-yakaderera mashandisirwo emagetsi inogoneka nekuda kweiyo nRF5340's nyowani, simba-yakagadziridzwa multiprotocol radio, iyo inopa TX ikozvino ye3.4 mA (0 dBm TX simba, 3 V, DC/DC) uye RX ikozvino ye2.7 mA (3 V, DC/DC). Ikozvino yekurara yakaderera se0.9 µA. Pamusoro pezvo, nekuti macores anogona kushanda akazvimirira, vagadziri vane shanduko yekugonesa mashandiro ekushandisa simba, throughput, uye yakaderera latency mhinduro.
"NRF Connect SDK yakakoshawo mukati me LE Audio yekuvandudza maitiro, padivi peruzivo rwehunyanzvi rwehunyanzvi uye mainjiniya ekushandisa akapihwa neNordic," anodaro Ouyang.
