Imodyuli ephucukileyo yoyilo lwemveliso yeaudiyo engenazingcingo esekwe kwiNordic Semiconductor's NFF5340 I-SoC ye-multiprotocol ephezulu, isungulwe yinkampani ye-IoT, i-Shenzhen Feasycom. Imodyuli ye-'FSC-BT631D' ibonelelwa nge-compact 12 by 15 by 2.2 mm package, kwaye ichazwa yinkampani njengeyokuqala kwihlabathi. Bluetooth® imodyuli enokuxhasa zombini Leaudiyo Audio kunye neBluetooth Classic. Ukongeza kwi-nRF5340 SoC, imodyuli idibanisa i-chipset ye-Bluetooth Classic ye-transceiver yokuvumela ukusetyenziswa kwe-audio ye-Bluetooth yelifa.
Isizukulwana esilandelayo seaudio engenazingcingo
"LE Audio sisizukulwana esilandelayo somsindo weBluetooth," utshilo uNan Ouyang, i-CEO e-Shenzhen Feasycom. "Yenza ukuhanjiswa komsindo ngeBluetooth LE kunokwenzeka ngokusebenza okuphuculweyo kumgangatho wesandi, ukusetyenziswa kwamandla, i-latency, kunye ne-bandwidth. Njengoko i-shishini litshintsha ukusuka kwi-Classic Audio ukuya kwi-LE Audio, abaphuhlisi bemveliso ye-wireless audio bafuna isisombululo esinokuxhasa zombini iinguqulelo, kutheni siye saphuhlisa imodyuli ye-FSC-BT631D."
"I-nRF Connect SDK nayo yayixabiseke kuyo yonke inkqubo yophuhliso lwe-LE Audio."
Umzekelo, izisombululo zezixhobo zomsindo ezisebenzisa imodyuli yeFeasycom zinokuqhagamshela kwizixhobo zomthombo weaudio ezifana ne-smartphone, ilaptop okanye iTV usebenzisa iBluetooth Classic, emva koko idlulisele iaudio kwinani elingenamkhawulo lezinye izixhobo zeLE Audio usebenzisa iAuracast™ yokusasaza iaudio.
Imodyuli isebenzisa i-nRF5340 SoC's dual Arm® Cortex®-M33 processors – ibonelela ngenkqubo yokusebenza ephezulu ekwaziyo iDSP kunye neFloating Point (FP) ecaleni kweprosesa enokucwangciswa ngokupheleleyo, yothungelwano lwamandla aphantsi kakhulu. Undoqo wesicelo ulawula zombini i-LE Audio codec kunye ne-codec ye-classic ye-Bluetooth yomsindo, ngelixa i-Bluetooth LE protocol ilawulwa yiprosesa yenethiwekhi.
Inkxaso yeeprothokholi ezininzi
Uqhagamshelo lwe-LE Audio lwenziwa lwenzeke nge-nRF5340 SoC's 2.4 GHz multiprotocol radio equkethe i-3 dBm yamandla aphumayo kunye -98 dBm RX ubuntununtunu kubhajethi yekhonkco ye-101 dBm. Lonomathotholo ukwaxhasa ezinye iiprothokholi eziphambili zeRF ezibandakanya iBluetooth 5.3, iBluetooth Direction Finding, udederhu olude, iBluetooth mesh, Thread, Zigbee, kunye ne ANT™.
"Sikhethe i-nRF5340 SoC kuba ifumene ukuhlalisana okuzinzileyo kwe-LE Audio kunye neBluetooth Classic ebiyeyona nto iphambili kwesi sicelo," utshilo u-Ouyang. "Ukusebenza kwee-CPU ezimbini ezingundoqo, ukusebenza kakuhle kwamandla, kunye nokusebenza kweRF zezinye izinto kwisigqibo."
Ukusetyenziswa kwamandla aphantsi kakhulu kwenziwa ngenxa yerediyo entsha ye-nRF5340, ephuculweyo ye-multiprotocol, enika i-TX yangoku ye-3.4 mA (0 dBm TX amandla, 3 V, DC/DC) kunye ne-RX yangoku ye-2.7 mA (3 V, DC/DC). Umsinga wokulala uphantsi njenge-0.9 µA. Ukongezelela, ngenxa yokuba ii-cores ziyakwazi ukusebenza ngokuzimeleyo, abaphuhlisi banokuguquguquka kokuphucula ukusebenza kokusetyenziswa kwamandla, i- throughput, kunye ne-low latency response.
"I-nRF Connect SDK ikwaxabiseke kuyo yonke inkqubo yophuhliso lomsindo we-LE, ecaleni kolwazi olugqwesileyo lobuchwephesha kunye neenjineli zesicelo ezinikezelwe nguNordic," utshilo u-Ouyang.
