Imodi yokulala nemodi yokusebenza
Imodi Yokulala Okujulile: Inzwa ayinakho ukwenza kusebenze kwe-NB-loT. Le modi isetshenziselwa ukulondoloza nokuthunyelwa ukuze konge impilo yebhethri.
Imodi yokusebenza: Kule modi, inzwa izosebenza njengenzwa ye-NB-loT yokujoyina inethiwekhi ye-NB-loT futhi ithumele idatha yenzwa kuseva. Emkhatsini ngamunye sampling/tx/rx ngezikhathi ezithile, inzwa izoba kumodi ye-IDLE), kumodi ye-IDLE, inzwa inokusetshenziswa kwamandla okufanayo njengemodi yokulala Okujulile.
Inkinobho nama-LED
Qaphela: Uma idivayisi yenza uhlelo, izinkinobho zingase zingavumelekile. Kungcono ukucindezela izinkinobho ngemva kokuba idivayisi isiqedile ukwenza uhlelo.
BLE uxhumano
I-SN50v3-NB isekela ukumisa okukude kwe-BLE kanye nokuvuselelwa kwe-firmware.
I-BLE ingasetshenziselwa ukulungisa ipharamitha yenzwa noma ukubona okukhiphayo kwe-console kusuka kunzwa. I-BLE izosebenza kuphela esimweni esingezansi:
- Cindezela inkinobho ukuze uthumele i-uplink
- Cindezela inkinobho kudivayisi esebenzayo.
- Amandla Edivayisi avuliwe noma setha kabusha.
Uma lungekho uxhumo lomsebenzi ku-BLE kumasekhondi angu-60, inzwa izovala imojuli ye-BLE ukuze ingene kumodi yamandla aphansi.
Phina Izincazelo , Ukushintsha kanye Nesikhombisi-ndlela se-SIM
I-SN50v3-NB isebenzisa ibhodi lomama elingezansi.
Ijumper JP2
Vula idivayisi uma ufaka lesi sigameko.
Imodi ye-BOOT / SW1
- I-ISP: imodi yokuthuthukisa, idivayisi ngeke ibe nesiginali kule modi. kodwa ilungele ukuthuthukisa i-firmware. I-LED ngeke isebenze. I-Firmware ngeke isebenze.

Setha kabusha Inkinobho
Cindezela ukuze uqalise kabusha idivayisi.
Isikhombisi-ndlela sekhadi le-SIM
Bona lesi sixhumanisi. Ungayifaka kanjani i-SIM Card.
Sebenzisa i-SN50v3-NB ukuze uxhumane ne-loT Server
Thumela idatha kuseva ye-loT ngenethiwekhi ye-NB-loT
I-SN50v3-NB ifakwe imojula ye-NB-loT, i-firmware elayishwe ngaphambili ku-SN50v3-NB izothola idatha yemvelo ezinzwa futhi ithumele inani kunethiwekhi yendawo ye-NB-loT ngemojula ye-NB-loT. Inethiwekhi ye-NB-loT izodlulisela leli nani kuseva ye-loT ngephrothokholi echazwe yi-SN50v3-NB.
Ngezansi kukhombisa ukwakheka kwenethiwekhi:
I-SN50v3-NB kunethiwekhi ye-NB-loT
Kunezinguqulo ezimbili: -GE kanye nenguqulo -1 D ye-SN50v3-NB.
Inguqulo ye-GE: Le nguqulo ayifaki ikhadi le-SIM noma ikhombe kunoma iyiphi iseva ye-loT. Umsebenzisi udinga ukusebenzisa i-AT Commands ukulungiselela ngezansi izinyathelo ezimbili zokusetha i-SN50v3-NB ukuthumela idatha kuseva ye-loT.
- Faka i-NB-loT SIM khadi bese ulungisa i-APN. Bona imiyalelo yokunamathisela Inethiwekhi.
- Setha inzwa ukuze ukhombe kuseva ye-loT. Bona imiyalelo yokulungisa ukuze uxhume amaseva ahlukene.
Ngezansi kukhombisa umphumela weseva ehlukile njengokubuka nje.
Inguqulo ye-1 D: Le nguqulo inekhadi le-SIM elingu-1 le-NCE elifakwe ngaphambili futhi lilungiselele ukuthumela inani ku-DataCake. Umsebenzisi Udinga nje ukukhetha uhlobo lwenzwa ku-DataCake futhi Vuselela i-SN50v3-NB futhi umsebenzisi uzokwazi ukubona idatha ku-DataCake. Bona lapha ukuze uthole I-DataCake Config Instruction.
Imodi Yokusebenza & Faka i-Payload
I-SN50v3-NB inemodi yokusebenza ehlukile yokuxhumeka kwezinhlobo ezahlukene zezinzwa. Lesi sigaba sichaza lezi zindlela. Umsebenzisi angasebenzisa i-AT Command AT +CFGMOD ukusetha i-SN50v3-NB kumamodi ahlukene okusebenza.
Okwesiboneloample:
