Cov ntaub ntawv khoom

RYLR993 module yog LoRa SOC core-based ntaus ntawv uas siv cov lus txib AT tsim los ntawm REYAX rau kev tswj cov module. Lub module txhawb LoRaWAN kev sib txuas lus thiab muab cov yam ntxwv xws li kev ua kom los ntawm tus kheej, kev ua kom huab cua, thiab siv xov tooj cua ntev. Lub module kuj txhawb kev siv cov yuam sij, IDs, thiab EUIs rau kev tswj hwm lub hom phiaj. Tsis tas li ntawd, lub module tuaj yeem siv los koom thiab xa cov ntaub ntawv ntawm LoRa network thiab ua cov kev xeem xov tooj cua.

Cov lus qhia siv khoom

Txhawm rau siv RYLR993 module, tus neeg siv yuav tsum xa AT cov lus txib mus rau lub module siv lub serial interface. AT cov lus txib tau muab los ntawm REYAX muaj cov kab ntawv luv luv uas tuaj yeem siv los ua ntau yam haujlwm xws li koom nrog LoRa network, xa cov ntaub ntawv mus rau lub network, thiab teeb tsa cov kev txwv. Tus neeg siv tuaj yeem tswj hwm cov yuam sij, IDs, thiab EUIs siv lub module.
Rau example, txhawm rau koom nrog LoRa network, tus neeg siv tuaj yeem xa cov lus txib hauv qab no:

  • AT+JOIN
    • Txhawm rau txheeb xyuas cov xwm txheej txuas, tus neeg siv tuaj yeem xa:
  • AT + LINKC
    • Txhawm rau xa cov ntaub ntawv mus rau LoRa network, tus neeg siv tuaj yeem siv cov lus txib hauv qab no:
  • AT+SEND
    • Lub RYLR993 module kuj txhawb nqa xov tooj cua cov lus txib. Txhawm rau ua qhov ntsuas xov tooj cua, tus neeg siv tuaj yeem siv cov lus txib hauv qab no:
  • AT+RADIO = 1
    • Yog xav paub ntxiv txog kev siv RYLR993 module, thov mus saib cov khoom siv phau ntawv.

Tshajview

Cov ntu hauv qab no muaj cov lus piav qhia interface, AT cov lus txib txhais, thiab cov lus piav qhia ntawm qee qhov kev siv thiab ntawm cov software embedded.

AT cov lus txib

Cov lus txib AT yog tus qauv tsim los ntawm REYAX los tswj cov qauv. Cov lus txib teeb tsa muaj cov kab ntawv luv luv rau kev ua haujlwm xws li kev koom ua ke, kev sib pauv ntaub ntawv thiab kev teeb tsa.
Cov lus txib AT yog siv los tsav LoRa module thiab xa cov ntaub ntawv. Cov lus txib AT raug xa los ntawm UART.

  • Baud tus nqi: 9600
  • Data: 8 ib
  • Parity: tsis muaj
  • Nres: 1 ntsis
  • Flow control: tsis muaj

Tag nrho cov lus txib yog ntawm daim ntawv AT + XXX, nrog XXX denoting cov lus txib. Cov kev coj cwj pwm hauv qab no muaj:

  • AT+XXX? muab kev pab luv luv ntawm cov lus txib (xws li AT + DEUI?).
  • AT + XXX yog siv los khiav cov lus txib (xws li AT + JOIN).
  • AT+XXX=? yog siv kom tau tus nqi ntawm cov lus txib (xws li AT + CFS =?).
  • AT+XXX = yog siv los muab tus nqi rau cov lus txib (xws li AT + SEND = 2: Nyob zoo).

Cov zis ntawm cov lus txib yog muab rau ntawm UART. Cov zis hom yog feem ntau:STMICROELECTRONICS-STM32L0-Ultra-Low-Power-MCUs-FIG- (1)

Xav txog: 

  • rov qab thaum pab AT+XXX? thiab tau txais AT + XXX =? cov lus txib tau khiav.
  • thiab stands rau carriage rov qab thiab kab noj.
  • Thaum tsis muaj nqi rov qab, ces tsis rov qab los lawm.
  • Txhua qhov kev hais kom ua, tshwj tsis yog ATZ (MCU rov pib dua), rov qab cov kab xwm txheej, uas yog ua ntej thiab ua raws . Cov xwm txheej ua tau yog:
    • OK: hais kom ua kom raug yam tsis muaj qhov yuam kev.
    • AT_ERROR: generic yuam kev
    • AT_PARAM_ERROR: parameter ntawm cov lus txib tsis raug.
    • AT_BUSY_ERROR: LoRa network tsis khoom, yog li cov lus txib tsis tuaj yeem ua tiav.
    • AT_TEST_PARAM_OVERFLOW: parameter ntev dhau lawm.
    • AT_NO_NETWORK_JOINED: LoRa network tsis koom nrog.
    • AT_RX_ERROR: Kev kuaj pom yuam kev thaum lub sijhawm txais tos ntawm cov lus txib

Cov ntsiab lus ntxiv ntawm txhua qhov lus piav qhia thiab examples tau muab rau hauv ntu tom ntej. Txhua qhov lus txib ua ntej los ntawm # yog muab los ntawm tus tswv tsev rau lub module, ces qhov rov qab ntawm module yog luam tawm.

AT_RX_ERROR

Nyob rau hauv rooj plaub ntawm AT_RX_ERROR, cov lus txib yog corrupted thaum tau txais hauv AT_Slave. Li no cov lus txib tsis khiav.
Txawm li cas los xij, nyob rau hauv rooj plaub ntawm cov lus txib ntev, qee cov cim spurious tseem tuaj yeem nyob hauv cov kab, npaj ua tiav raws li cov lus txib. Yog li, yog tias tus neeg siv tau txais AT_RX_ERROR, tus neeg siv yuav tsum xub xa kom tshem tawm cov kab, thiab xa rov qab rau tib lo lus txib kom nws ua tiav.
