Merhabalar lora 868t20d sahibiyim usb üzerinden kanalı ayarlayıp frekansı 868 olarak görebiliyorum ama arduino üzerinden getparameters ile okuma yaptığım zaman frekansın 400 ile 500 arasında olduğu gözüküyor sorunu nasıl çözebilirim? Ayrıca ayarladığım addl ve addh da farklı gözüküyor.
Soru yeni cevaplara kapalıdır.

işte USB parametre ayarlama cihazı olmadan iş biraz zor . Şimdi hangi ayarı içine attın, acaba cihaz ne aldı bilmek imkansız. Bir tane usb cihazından alsan ömür boyu rahat edersin bana da dua edersin :).
Kodda anormal başka bir şey gözüme çarpmadı. birde devrenin fotoğraflarını at bakayım. mümkünse bağlantıları net çıksın.
Bu arada hala diğer firmanın ne cevap verdiğini merak ediyorum. söylemedin. Alp var orda o mu cevap yazdı.

Merhabalar kullandığım devre bu şekilde vericide arduino ve sensörleri harici olarak besliyorum alıcıda ise arduino üzerinden besleme yapıyorum ancak sorunu çözemedim. Ayrıca parametre ayarlarını kod üzerinden 3v3 bağlayarak ayarlıyorum. [apcode language="php"]

Hayır 2 lora arasındaki iletişimi maalesef kuramadım. Sorun hala devam etmekte.
German Clubber Cevaplanan soru Ağustos 6, 2021
Sanırım başka yerden satın almıştınız lorayı. Acaba sorunun çözüldü mü?
