Hallo @jamct,
schönes Projekt, vielen Dank dafür!
Im Artikel ist noch ein Ordner "05_optimized" erwähnt, könntest du den ggf. noch ergänzen?
Viele Grüße,
Tobias
Ich habe jetzt eine Woche lang versucht die ATTiny84 mit Platformio zu programmieren, habe alle möglichen Pinbelegungen ausprobiert und bin gescheitert. Jetzt bin ich auf die absurde Idee gekommen, den ATTiny84 mit der Arduino-IDE zu flashen -> und siehe da: Heureka! Es funktioniert!
The Arduino IDE reports, that the zip files does not contain a valid library.
Checked with Arduino version 1.8.9 and 1.8.10.
Hi,
in line 67 of radio-mailbox/03_lora_test/lib/RFM95/RFM95.cpp there is
//Spreading factor 7, PayloadCRC On
RFM_Write(0x1E,0xB4);
My gateway receives the packages with SF7 as expected - or rather not:
From the documentation of the chip I understand that bits 4-7 of the 1E register
(i.e. the higher hex digit) give the SF, so I would expect the SF to be B=11 and
not 7... How can I use a larger SF (for longer range)?
Best, Stefan
