Tlhahisoleseding ya Sehlahiswa

Mojule oa RYLR993 ke sesebelisoa sa mantlha sa LoRa SOC se sebelisang taelo ea AT e behiloeng ke REYAX bakeng sa ho laola module. Mojule ona o ts'ehetsa puisano ea LoRaWAN mme o fana ka likarolo tse kang ts'ebetso ka ho iketsetsa motho, ts'ebetso ea moea, le theknoloji ea seea-le-moea sa nako e telele. Mojule o boetse o ts'ehetsa ts'ebeliso ea linotlolo, li-ID, le li-EUI molemong oa tsamaiso. Ho feta moo, mojule o ka sebelisoa ho kopanya le ho romella data ho netweke ea LoRa le ho etsa liteko tsa radio.

Litaelo tsa Tšebeliso ea Sehlahisoa

Ho sebelisa mojule oa RYLR993, mosebelisi o tlameha ho romella litaelo tsa AT ho module a sebelisa sebopeho sa serial. Taelo ea AT e behiloeng ke REYAX e na le letoto la likhoele tse khutšoane tsa mongolo tse ka sebelisoang ho etsa ts'ebetso e fapaneng joalo ka ho ikopanya le marang-rang a LoRa, ho romella data ho marang-rang, le ho beha li-parameter. Mosebelisi a ka boela a laola linotlolo, li-ID, le li-EUI a sebelisa mojule.
Bakeng sa mohlalaample, ho kenela marang-rang a LoRa, mosebelisi a ka romella taelo e latelang:

  • KA+KENYA
    • Ho sheba boemo ba sehokelo, mosebelisi a ka romella:

    • Mojule oa RYLR993 o boetse o tšehetsa litaelo tsa tlhahlobo ea seea-le-moea. Ho etsa tlhahlobo ea radio, mosebelisi a ka sebelisa taelo e latelang:
  • HO+RADIO=1
    • Bakeng sa tlhaiso-leseling e batsi mabapi le ho sebelisa mojule oa RYLR993, ka kopo sheba bukana ea mosebelisi oa sehlahisoa.
