Okay maybe I am messing things up then.
What I did is I copied the data in hex that I received on TTN-console which looks something like “17 00 7d 00 2a 00 03 12 fe 03 07 00” and from what I get data like temperature and stuff like that.
So I took the hex-data and encoded it as Base64 which give me something like “FyAAIH0gACAqIAAgAyASIP4gAyAHIAA=”.
Then I compared that with what I see what goes to TTN which looks something like “ABgyh3J4iIVDRMAE0H7Vs3DJROV0IOM=”. The exact same data is also send to my raspi. So in order to decode it and get e.g. the temperature I need to understand how to derive
“FyAAIH0gACAqIAAgAyASIP4gAyAHIAA=” out of
“ABgyh3J4iIVDRMAE0H7Vs3DJROV0IOM=”.
As I see it, it is not encrypted, because I see data like the following in the packets that is not encrypted:
“codr”:“4/5”, “lsnr”:8.8, “rssi”:-81 .
Or am I wrong here? If so I would research with what standard and what key the data is encrypted and all my problems are solved.
Many thanks for your answers and I hope I made my problem clear. I really appreciate it!!
