Kule demo, I-Arduino IDE yethu iya kubandakanya ithala leencwadi kunye nomzekelo wemizobo enohlengahlengiso oluncinci ukwenza unxibelelwano phakathi kweemodyuli zethu zeLoRa. Landela iSketch nje ukuba uvule i-Arduino IDE ukongeza ithala leencwadi. Emva kokwenza oku, khangela i “LoRa Radio” kwaye ukhethe ilayibrari, emva koko ucofe ku-install.
Sebenzisa iFayile -> umzekelo -> ILoRa, emva koko uvule ukuthumela nokwamkela iinkqubo zemodyuli yeLoRa njengoko kubonisiwe ngezantsi.
Kuzo zonke 5 imizuzwana, a “Mholweni” ithunyelwa yinkqubo yomThumeli ngelixa isonyusa ixabiso lekhawuntara. Oku kufunyanwa ngumamkeli othi kamva aprinte ixabiso leRSSI kwimonitha yothotho. Ekuqaleni, qinisekisa ukuba uyalwenza utshintsho kwi LoRa.begin() umsebenzi. Ngokuzenzekelayo iseti ukuba isebenze kwimodyuli ye-LoRa 915MHz, yiyo loo nto inkqubo inakho “LoRa.qalisa(915E6)”.
Emva kokuqinisekisa ukuba unxibelelwano lwenziwe ngokufanelekileyo, kwaye imodyuli yeLoRa idityaniswe ngokuchanekileyo kunye ne-eriyali, layisha inkqubo xa sele ilungile.
Unxibelelwano olungenazingcingo lweLoRa kunye neArduino
Vula i-serial monitor yebhodi yeArduino emva kokulayisha inkqubo. Umhloli wothotho lomthumeli kufuneka abonise ixabiso elithunyelweyo kwaye kamva lifunyenwe kwaye liboniswe kwimonitha yothotho lwemonitha.
Kubalulekile ukuba uhlale ujonga ixabiso lemodyuli ye-LoRa ye-RSSI kuwo wonke umyalezo ofunyenweyo. Ixabiso le-RSSI liza kuba libi ngalo lonke ixesha. Kumboniso wethu, ijikelezile -68. Oku kungenxa yokuba amandla omqondiso uba namandla njengoko ixabiso le-RSSI lisondela ku-zero.
