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.
