Finally received my DVB-T/DAB/FM dongle and more precisely my R820T tuner.
This, with the proper drivers (here), will allow me to « listen » to my RF433 radio devices.
Even better I can record my signal in audacity using a « virtual audio cable« . (note that are free alternatives).
Or else I can display my packets using rtl_433_win32 (although not decoded properly).
Note : ab 53 32 cb 54 d5 4b 2a 80 is a chacon remote control (to switch on/off a 220v plug outlet).
We can see in audacity the pattern repeated 5 times.
Zooming in one pattern, we can see high and low bits.
Now the challenge is the following :
-snif a RF433 packet and decode it
-replay it with my Arduino+CC1101
How fun 🙂
