Lokisa LDDS75 ho hokela marang-rang a LoRaWAN
Kamoo e sebetsang kateng
LDDS75 e hlophisitsoe joalo ka LoRaWAN OTAA Class A mode ka ho sa feleng. E na le linotlolo tsa OTAA tsa ho kenela marang-rang a LoRaWAN. Ho hokela marang-rang a LoRaWAN, o hloka ho kenya linotlolo tsa OTAA ho seva sa LoRaWAN IoT le matla ho LDDS75. Haeba ho na le tšireletso ea marang-rang ea LoRaWAN, e tla ikamahanya le marang-rang ka OTAA ebe e qala ho romela boleng ba sensor.
Haeba u sa khone ho beha linotlolo tsa OTAA ho seva sa LoRaWAN OTAA, 'me u tlameha ho sebelisa linotlolo tse tsoang ho seva, u ka sebelisa AT Commands ho beha linotlolo ho LDDS75.
Tataiso e potlakileng ea ho hokela ho seva ea LoRaWAN (OTAA)
E latelang ke example mokhoa oa ho kenela TTN LoRaWAN Network. Ka tlase ke mohaho oa marang-rang; re sebelisa LG308 joalo ka tsela ea LoRaWAN ho example.
LDDS75 ho LoRaWAN Network
LG308 e se e ntse e hlophisitsoe ho hokela marang-rang a TTN , kahoo seo re se hlokang hona joale ke ho lokisa seva sa TTN.
Mohato oa 1: Theha sesebelisoa ho TTN ka linotlolo tsa OTAA ho tsoa LDDS75.
LDDS75 ka 'ngoe e romelloa ka setikara se nang le linotlolo tsa sesebelisoa sa kamehla, mosebelisi a ka fumana setikara sena ka lebokoseng. e shebahala joalo ka tlase.
Bakeng sa ngoliso ea OTAA, re hloka ho seta APP EUI/ APP KEY/ DEV EUI. Mohlomong seva se seng ha se hloke ho seta APP EUI.
Kenya linotlolo tsena ho portal ea LoRaWAN Server. Ka tlase ke setšoantšo sa skrini sa TTN:

Hlahisa Lintlha ho Mydevices IoT Server
Mydevices e fana ka sebopeho sa botsoalle sa batho ho bonts'a data ea sensor, hang ha re e-na le data ho TTN, re ka sebelisa Mydevices ho hokahanya le TTN le ho bona lintlha ho Mydevices. Mehato e ka tlase ke ena:
Mohato oa 1: Netefatsa hore sesebediswa sa hao se hlophisitswe mme se hoketswe ka nepo ho netweke ka nako ena.
Mohato oa 2: Ho lokisa Kopo ho fetisetsa data ho Mydevices o tla hloka ho eketsa kopanyo. Ho eketsa kopanyo ea Mydevices, etsa mehato e latelang:
Mohato oa 3: Theha ak'haonte kapa kena ho Mydevices.
Mohato oa 4: Batla LDDS75 'me u kenye DevEUI. 
Kamora ho eketsoa, data ea sensor e fihla TTN, e tla fihla le ho bonts'a ho Mydevices.
