Hi Omri,
I was able to decode NRF24L01+ and Bluetooth Low
Energy protocols using
RTL-SDR. with some very cheap analog trickery.
This opens a world of possibilities at the ISM 2.4Ghz band.
Very nice. And good find for the cheap downconverter source :)
I added a link to the code and the blog post in the "Known Apps" section.
Cheers,
Sylvain
