• LoRa module yog nyob rau hauv dormant hom feem ntau. Yog tias MCU cuam tshuam nrog lub module, nws yuav tsum tsa LoRa module ua ntej thiab xa AT cov lus qhia rau LoRa module.
• Tom qab ntawd PE7 (GPI04) yog tus pin los tsa LoRa module rau MCU; Ib yam li ntawd, yog tias lub module cuam tshuam nrog MCU sab nraud (Xa AT cov lus qhia), nws yuav tsum tau tsa MCU sab nraud (ces xa AT cov lus qhia ). PE6 yog tus pin sib thooj.
• PE6 thiab PE7 muaj "npaj" lub xeev kev qhia ua haujlwm tshwj tsis yog lub zog sawv. PE6 thiab PE7 feem ntau yog nyob rau theem siab teeb liab thiab tig qis thaum tshwm sim. Kev sib cuam tshuam yuav tsum tau rov qab mus rau lub teeb liab siab.

Kev sib cuam tshuam ntawm MCU thiab LoRa module

Hauv kev sib cuam tshuam no, MCU muab AT qhia rau LoRa, thiab LoRa tuaj yeem muab AT qhia rau MCU. Txhawm rau txo qis kev siv hluav taws xob, LoRa thiab MCU feem ntau nyob hauv lub xeev dormant. Txhua tus ntawm lawv tuav nws cov lus. Thaum nws xav tau lwm tus, nws yuav tsa lwm tus thiab muab AT qhia rau lwm tus.
Thaum AT cov lus qhia raug xa mus rau ob sab, cov chav kawm ntxiv yuav tshwm sim thaum muaj tib lub sijhawm. Yog li, tus tsim rau qhov no yog "ib nrab duplex" hom. Ntawd yog: tsuas yog ib sab tuaj yeem xa cov lus qhia ib zaug. Yog li ntawd, ua ntej ob tog xa cov lus qhia, nws yuav tsum tau saib xyuas seb lwm tus xav xa cov lus qhia lossis tsis. Yog tias lwm sab tau "tuav txoj cai xa cov ntaub ntawv", koj yuav tsum tau tos kom txog thaum qhov kev sib tham tam sim no ua tiav ua ntej pib.
Cov hauv qab no yog cov txheej txheem ua tiav rau kev pib AT kev qhia ntawm ob qho kawg.
Cov txheej txheem tiav ntawm MCU pib muaj kev cuam tshuam nrog LoRa module.

Nco ： 

1. Kauj Ruam 1 txhawm rau txheeb xyuas PE6, yog " mloog ua ntej ua ntej hais", kom ntseeg tau tias "lwm tus neeg tsis xa nws tus kheej thaum xa". Yog tias PE6 twb muaj cov teeb liab qis, lwm tus neeg xa nws. Lub sijhawm no, tos kom lwm tus xa rov qab (tsis txhob mus rau theem 2 tam sim ntawd).
2. Kauj ruam 2 kom cia lub PE7 nyob rau hauv qis theem teeb liab, yog tiag tiag mus "tshem txoj cai hais lus" ; —- vim tias lwm tus neeg tuaj xyuas yog tias PE7 nyob rau theem qis qis ua ntej xa nws.
3. Kauj Ruam 3, PE6 tig mus rau hauv cov teeb liab qis hauv cov lus teb rau MCU, qhia MCU tias "Kuv tau sawv thiab npaj rau kev txais tos, koj tuaj yeem xa" ;
4. Kauj ruam 5 yog PE6 tig mus rau theem siab teeb liab, nruj me ntsis hais lus, yog LoRa module kuaj pom qhov chaw nres nkoj serial xa cov ntaub ntawv thiab tam sim ntawd tig PE6 mus rau theem siab teeb liab (tsis yog tos rau AT cov lus qhia yuav raug xa tiav.);
5. Los ntawm kauj ruam 6, ib puag ncig ntawm kev sib cuam tshuam tiav.
   Thaum ob tog xa cov ntaub ntawv, "tshem txoj cai hais lus".

Qhov tseeb, tag nrho cov lus qhia AT xa daim ntawv MCU rau LoRa yuav cia LoRa kom muaj cov lus teb sib xws (saib rau AT cov lus qhia teeb tsa tom qab). Yog li, tom qab MCU xa cov lus qhia mus rau LoRa, nws tuaj yeem mus pw tsaug zog, lossis tos LoRa teb ua ntej dormant. Lub sij hawm teb no, ib txwm nyob hauv ob peb ms.(Cov txheej txheem ntawm peb tuple cov lus qhia yuav siv sij hawm ntev, nyob ib ncig ntawm 200 ms).

Cov txheej txheem ua tiav ntawm LoRa module los pib muaj kev cuam tshuam nrog MCU
Ntxiv rau AT cov lus teb, LoRa module tseem yuav nquag pib MCU cov lus qhia, xws li kev nkag mus rau hauv network, txais cov ntaub ntawv, sijhawm tawm, thiab lwm yam.
Tag nrho cov txheej txheem kev sib cuam tshuam yog qhov pib zoo ib yam, tsuas yog rov qab.

Nco tseg: 

1. Hauv kauj ruam 3, yog tias PE 7 tsis tig lub teeb liab qis, ces LoRa tseem yuav xa AT cov lus qhia tom qab 50ms timeout.
   Tom qab kauj ruam 5, LoRa module yuav tig mus rau hauv dormant txawm tias MCU hauv kauj ruam 6 hloov PE7 mus rau theem teeb liab.
