8 years ago Works fine with my HackRF One when I just tune to the proper frequency, but only one one of the advertising channels.
For example 2426 MHz channel index 38. Just edit the nrf_channel variable and set it to 26, becasue of the way the center_freq is calculated. You might also note the down sampling rate, I get stuff with both -b 1 or 2. I have not confirmed the data to be of known origin, but I get a lot of it in my environment compared to the two other advertising channels are also very silent for me. But it could still be noise from wifi and what not.
Hello,
I have a veraPlus controller with a Revogi bulb using bluetooth low energy. -->I try your tool, when I use defautl paquet-type which is nrf I get some data but nothing with btle: strange!
Here my outputs:

I change the grc fie to set center_freq to 2.405e9 and I use a HackRf:
