Hocam merhabalar sizlerden E22 900T22D model lora ve programlayıcı tedarik ettik haberleşme modüllerinin parametre ayararını sorunsuz bir biçimde yapabiliyoruz ancak sistemler arası haberleşmeyi bir türlüsağlayamıyoruz.Haberleşmeyi stm32 lerle kütüphanesiz bir şekilde gerçekleştirmeye çalışıyoruz.

Ek olarak kodların çalıştığına da eminiz çünkü 2 stm32 yi birbirine direkt oalrak UART ile haberleştirdiğimde uygulamam sorunsuz olarak çalışmakta.

sğlayamıyoruz.

Soru yeni cevaplara kapalıdır.

şurda STM32 ve Lora için güzel bir video var izlemenizi tavsiye ederim. https://www.youtube.com/watch?v=JG189GIko7k

Buyrun hocam bağlantıyı 2 modül içinde bu şekilde sağlamaktayım.

hocam sanki GND pini tam yerine oturmamış. loraya enerji gidip gitmediğini ve sinyal alıp almadığını önce kontrol edelim. bunun için AUX pinine 220 ohm direnc ve bir led bağlayın. led başta sabit yanıyorsa enerji vardır demek. sinyal gönderme sırasında led yanıp söorsa mesaj gönderiyor veya alıyordur. demek. önce sistemin enerjisi var mı yok mu bakalım. Bu arada beyaz boardları hiç bir zaman tavsiye etmiyorum Muhakkak PCB kullanın. Bu durumda da bizdeki PCB dahi olsaydı lorayı yerine takardınız. NANO daki pinlerin yerine 5v, rx,tx ve m0 m1 pinlerini nucleo kartınız üzerinden aktarsanız daha sağlıklı çalışırdı.
