Ulwazi Lomkhiqizo

Imojula ye-RYLR993 iyithuluzi elisekelwe ku-LoRa SOC elisebenzisa umyalo we-AT osethwe i-REYAX ukuze ilawule imojuli. Imojula isekela ukuxhumana kwe-LoRaWAN futhi inikeza izici ezifana nokwenza kusebenze ngokwenza kube ngokwakho, ukusebenza emoyeni, kanye nobuchwepheshe bomsakazo webanga elide. Imojuli futhi isekela ukusetshenziswa kokhiye, ama-ID, nama-EUI ngezinjongo zokuphatha. Ukwengeza, imojula ingasetshenziswa ukujoyina nokuthumela idatha kunethiwekhi ye-LoRa nokwenza izivivinyo zomsakazo.

Imiyalo yokusetshenziswa komkhiqizo

Ukuze usebenzise imojula ye-RYLR993, umsebenzisi kufanele athumele imiyalo ye-AT kumojula esebenzisa isixhumi esibonakalayo seserial. Umyalo we-AT ohlinzekwe yi-REYAX uqukethe uchungechunge lwezintambo zombhalo omfushane ezingasetshenziswa ukwenza imisebenzi ehlukahlukene njengokujoyina inethiwekhi ye-LoRa, ukuthumela idatha kunethiwekhi, nokusetha imingcele. Umsebenzisi angakwazi futhi ukuphatha okhiye, ama-ID, nama-EUI esebenzisa imojula.
Okwesiboneloample, ukujoyina inethiwekhi ye-LoRa, umsebenzisi angathumela umyalo olandelayo:

  • AT+JOIN
    • Ukuze uhlole isimo sesixhumanisi, umsebenzisi angathumela:
  • AT+LINKC
    • Ukuthumela idatha kunethiwekhi ye-LoRa, umsebenzisi angasebenzisa umyalo olandelayo:
  • AT+THUMELA
    • Imojula ye-RYLR993 iphinde isekele imiyalo yokuhlola umsakazo. Ukwenza uhlolo lomsakazo, umsebenzisi angasebenzisa umyalo olandelayo:
  • KU+RADIO=1
    • Ukuze uthole ulwazi oluthe xaxa mayelana nokusebenzisa imojula ye-RYLR993, sicela ubheke imanuwali yomsebenzisi womkhiqizo.

ulwazi oluvamile

Umbhalo usebenza kumojula ye-REYAX RYLR993 okungamathuluzi asekelwe ku-LoRa SOC.

Kuphelileview

Izigaba ezilandelayo ziqukethe incazelo yesixhumi esibonakalayo, incazelo yemiyalo ye-AT, kanye nencazelo yamanye amacala okusetshenziswa kanye nesofthiwe eshumekiwe.

Imiyalo ye-AT

Isethi yomyalo we-AT iyindinganiso eyakhiwe yi-REYAX yokulawula imojula. Isethi yomyalo iqukethe uchungechunge lwezintambo zombhalo omfishane zokwenza imisebenzi efana nokujoyina, ukushintshana kwedatha nokusetha imingcele.
Imiyalo ye-AT isetshenziselwa ukushayela imojula ye-LoRa kanye nokuthumela idatha. Imiyalo ye-AT ithunyelwa nge-UART.

  • Izinga leBaud: 9600
  • Idatha: 8 bits
  • I-Parity: akukho
  • Yima: 1 bit
  • Ukulawulwa kokugeleza: akekho

Yonke imiyalo ingeyefomu AT+XXX, XXX echaza umyalo. Imiyalo elandelayo yokuziphatha iyatholakala:

  • AT+XXX? inikeza usizo olufushane lomyalo onikeziwe (ofana ne-AT+DEUI?).
  • I-AT+XXX isetshenziselwa ukuqalisa umyalo (ofana nokuthi AT+JOIN).
  • AT+XXX=? isetshenziselwa ukuthola inani lomyalo onikeziwe (ofana ne-AT+CFS=?).
  • AT+XXX= isetshenziselwa ukunikeza inani emyalweni (ofana nokuthi AT+THUMELA=2:Sawubona).

Umphumela wemiyalelo unikezwa ku-UART. Ifomethi yokukhiphayo ngokuvamile ithi:I-STMICROELECTRONICS-STM32L0-Ultra-Low-Power-MCUs-FIG- (1)

Kucatshangelwa: 

  • uyabuyiswa uma usizo AT+XXX? futhi uthole i-AT+XXX=? imiyalo iyaqhutshwa.
  • futhi imele inqola yokubuya kanye nesiphakeli somugqa.
  • Lapho lingekho inani elibuyiswayo, ke ayibuyiswa nhlobo.
  • Wonke umyalo, ngaphandle kwe-ATZ (ukusetha kabusha kwe-MCU), ibuyisela iyunithi yezinhlamvu yesimo, eyandulelwa futhi ilandelwe . Isimo esingaba khona yilesi:
    • Kulungile: umyalo ugijima ngendlela efanele ngaphandle kwephutha.
    • AT_ERROR: iphutha elejwayelekile
    • AT_PARAM_ERROR: ipharamitha yomyalo ayilungile.
    • AT_BUSY_ERROR: Inethiwekhi ye-LoRa imatasa, ngakho-ke umyalo awukwazanga ukuqeda.
    • AT_TEST_PARAM_OVERFLOW: ipharamitha yinde kakhulu.
    • AT_NO_NETWORK_JOINED: Inethiwekhi ye-LoRa ayijoyiniwe.
    • AT_RX_ERROR: ukutholwa kwephutha ngesikhathi sokwamukela umyalo

Imininingwane eyengeziwe encazelweni yomyalo ngamunye kanye nesibamplezi zinikezwa ezigabeni ezilandelayo. Umyalo ngamunye owandulelwa ngu-# unikezwa umsingathi kumojula, bese ukubuyiselwa kwemojula kuyaphrintwa.

AT_RX_ERROR

Esimeni se-AT_RX_ERROR, umyalo wonakaliswa uma utholwa ku-AT_Slave. Ngakho-ke umyalo awusebenzi.
Nokho, uma kunemiyalo emide, ezinye izinhlamvu ezingamanga zisengaba kulayini, zilungele ukucutshungulwa njengomyalo. Ngakho-ke, uma kwenzeka umsebenzisi ethola i-AT_RX_ERROR, umsebenzisi kufanele athumele kuqala ukususa ulayini, bese uthumela emuva umyalo ofanayo ukuze ucutshungulwe.
