Kuyanjana pakati pa MCU ndi gawo la LoRa

Pakuyanjana uku, MCU imapereka malangizo a AT kwa LoRa, ndipo LoRa ikhoza kupereka malangizo a AT ku MCU. Pofuna kuchepetsa kugwiritsa ntchito mphamvu, LoRa ndi MCU nthawi zambiri zimakhala zogona. Aliyense wa iwo amanyamula uthenga wake. Ikafuna ina, imadzutsa ina ndikupereka malangizo a AT kwa ina.
Malangizo a AT akatumizidwa mbali zonse ziwiri, maphunziro owonjezera amachitika nthawi imodzi. Choncho, mapangidwe a izi ndi "half duplex" mode. Ndiko kuti: mbali imodzi yokha ingatumize malangizo nthawi imodzi. Choncho, mbali iliyonse isanatumize malangizo, iyenera kuyang'anitsitsa ngati ina ikufuna kutumiza malangizo kapena ayi. Ngati mbali inayo "yatenga ufulu wotumiza zidziwitso", muyenera kudikirira mpaka mgwirizano womwe ulipo utatha musanayambe.
Zotsatirazi ndi njira yathunthu yoyambitsira malangizo a AT kumapeto onse awiri.
Njira yonse ya MCU imayambitsa kuyanjana ndi gawo la LoRa.

Zindikirani : 

1. Gawo 1 kuti muzindikire PE6, ndi "mvetserani kaye musananene" , kuonetsetsa kuti "mnzakeyo sakutumiza yekha potumiza" . Ngati PE6 ili kale ndi chizindikiro chotsika, gulu lina likutumiza. Panthawiyi, dikirani kuti gulu lina litumizenso (osapita ku sitepe 2 nthawi yomweyo).
2. Khwerero 2 kulola PE7 kukhala chizindikiro chotsika, ndiko "kulanda ufulu wolankhula"; -- chifukwa gulu lina limabwera kudzazindikira ngati PE7 ili mu siginecha yotsika isanatumize.
3. Khwerero 3, PE6 imasintha kukhala siginecha yotsika poyankha MCU, ndikuwuza MCU kuti "Ndadzutsidwa ndikukonzekera kulandila kwakanthawi, mutha kutumiza" ;
4. Gawo 5 ndi PE6 kutembenukira mu mkulu mlingo chizindikiro, mosamalitsa kulankhula, ndi gawo LoRa wapezeka doko siriyo kutumiza deta ndipo nthawi yomweyo kutembenukira PE6 mu mkulu mlingo chizindikiro (osati kuyembekezera AT malangizo kutumizidwa kutha.);
5. Ndi sitepe 6, kuzungulira kwa kuyanjana kumatsirizidwa.
   Pamene mbali ziwirizo zitumiza deta, "gwiritsani ufulu wolankhula" .

M'malo mwake, malangizo onse a AT atumiza fomu ya MCU ku LoRa ilola LoRa kukhala ndi yankho lofananira (onani malangizo a AT omwe ali kumbuyo). Chifukwa chake, MCU itatumiza malangizo ku LoRa, imatha kugona, kapena kudikirira LoRa kuti ayankhe asanagone. Nthawi yoyankha iyi, yodziwika bwino mu ma ms ochepa.

Njira yonse ya gawo la LoRa kuyambitsa kuyanjana ndi MCU
Kuphatikiza pa kuyankha kwa AT, gawo la LoRa lidzayambitsanso malangizo a MCU mwachangu, monga kupita patsogolo kwa netiweki, kulandila deta, kutha nthawi, ndi zina zotero.
