Module yotsogola yopangira zida zamawu opanda zingwe kutengera Nordic Semiconductor's Chiwerengero high-end multiprotocol SoC, yakhazikitsidwa ndi kampani ya IoT, Shenzhen Feasycom. Module ya 'FSC-BT631D' imaperekedwa mu phukusi la compact 12 ndi 15 ndi 2.2 mm, ndipo ikufotokozedwa ndi kampani ngati yoyamba padziko lapansi. Bluetooth® gawo lomwe lingathe kuthandizira onse awiri LE Audio ndi Bluetooth Classic. Kuphatikiza pa nRF5340 SoC, gawoli limaphatikiza chipset cha Bluetooth Classic transceiver kuti chithandizire kumvera nyimbo za Bluetooth.
M'badwo wotsatira wamawu opanda zingwe
"LE Audio ndi m'badwo wotsatira wa Bluetooth audio," akutero Nan Ouyang, CEO ku Shenzhen Feasycom. "Zimapangitsa kuti nyimbo ziziyenda pa Bluetooth LE zotheka ndi kupititsa patsogolo kamvekedwe ka mawu, kugwiritsa ntchito mphamvu, latency, ndi bandwidth. Pamene makampani akusintha kuchoka ku Classic Audio kupita ku LE Audio, opanga ma audio opanda zingwe amafunikira yankho lomwe lingathe kuthandizira mitundu yonseyi, yomwe ndi chifukwa chake tapanga gawo la FSC-BT631D."
"NRF Connect SDK inalinso yofunika kwambiri pakupanga LE Audio."
Mwachitsanzo, mayankho a zida zomvera pogwiritsa ntchito gawo la Feasycom amatha kulumikizana ndi zida zomvera monga foni yam'manja, laputopu kapena TV pogwiritsa ntchito Bluetooth Classic, kenako ndikutumiza zomvera ku zida zina zopanda malire za LE Audio pogwiritsa ntchito mawu owulutsa a Auracast™.
Gawoli limagwiritsa ntchito mapurosesa a nRF5340 SoC's dual Arm® Cortex®-M33 - popereka purosesa yogwira ntchito kwambiri yomwe imatha DSP ndi Floating Point (FP) pamodzi ndi purosesa yokhazikika, yotsika kwambiri. Pachiyambi cha pulogalamuyo imayang'anira onse LE Audio codec ndi codec yama audio akale a Bluetooth, pomwe protocol ya Bluetooth LE imayang'aniridwa ndi purosesa ya netiweki.
Thandizo la ma protocol angapo
Kulumikizana kwa LE Audio kumatheka kudzera pa wailesi ya nRF5340 SoC's 2.4 GHz multiprotocol yokhala ndi 3 dBm mphamvu yotulutsa ndi -98 dBm RX sensitivity pa bajeti yolumikizira ya 101 dBm. Wailesi iyi imathandiziranso ma protocol ena akuluakulu a RF kuphatikiza Bluetooth 5.3, Bluetooth Direction Finding, Long Range, Bluetooth mesh, Thread, Zigbee, ndi ANT™.
"Tidasankha nRF5340 SoC chifukwa idapeza mgwirizano wokhazikika wa LE Audio ndi Bluetooth Classic zomwe zinali zofunika kwambiri pakugwiritsa ntchito," akutero Ouyang. "Kugwira ntchito kwa ma CPU apawiri, mphamvu zamagetsi, komanso magwiridwe antchito a RF ndizinthu zina pachigamulocho."
Kugwiritsa ntchito mphamvu pang'onopang'ono kumatheka chifukwa cha wailesi yatsopano ya nRF5340, yowonjezera mphamvu ya multiprotocol, yomwe imapereka ma TX apano a 3.4 mA (0 dBm TX mphamvu, 3 V, DC/DC) ndi RX yapano ya 2.7 mA (3 V, DC/DC). Kugona kwapano kumakhala kotsika ngati 0.9 µA. Kuphatikiza apo, chifukwa ma cores amatha kugwira ntchito paokha, opanga amatha kusinthasintha kuti azitha kugwiritsa ntchito mphamvu zamagetsi, kutulutsa, komanso kuyankha kochepa kwa latency.
"NRF Connect SDK inalinso yofunika kwambiri panthawi yonse yachitukuko cha LE Audio, pamodzi ndi chidziwitso chaukadaulo komanso mainjiniya operekedwa ndi Nordic," akutero Ouyang.
