BladeRF: Trying to figure out how to set arguments to start

[Andrea99-beep]

Hello,

I am trying to use LTESniffer with a BladeRF device for downlink sniffing, but I would like to configure a few parameters specifically:

• Sampling rate: How can I set the sampling rate for the BladeRF device? Is there a way to adjust the sample rate via the configuration or command line arguments?
  

• Disabling SoapySDR: The program is attempting to use SoapySDR as a backend, but I want to use BladeRF directly without Soapy. How can I ensure that LTESniffer uses BladeRF and not SoapySDR? Are there any specific flags or settings I should configure?
  

For now I've tried in this way and I get this output:

sudo LTESniffer -a rf.device=bladeRF -A 2 -W 8 -f 806e6 -I 286 -m 0

Hi, unfortunately, I also dont have any experience with bladeRF, I only have USRP to test.
However, many users reported that Bladerf works well. So I will keep the issue open here for any advice from other users.
Thanks.

I'm testing using this command: LTESniffer -A 1 -W 4 -f xxxe6 -m 0 -g 30
He prints me "Processed 1000/1000 subframes" but It doesn't find any RNTI and also the ltesniffer_dl_mode.pcap is empty, as he hasn't sniffed anything, but I'm sure there is traffic going on.

Could you please copy and paste your terminal log including the command was used here?
