Analyzing recorded files does not work

[urddc1]

Hello everyone,

I have recently tried to use the sniffer from a captured file, but unfortunately does not matter what configuration I set for the recording, the sniffer cannot find any bluetooth packets in it. However, using inspectrum and the live capture option in the ice9-bluetooth-sniffer, I can certainly tell that the file does contain some of the Bluetooth packets.

I changed around the center frequency, the bandwidth and the sample rate to solve the issue, but yet with no success. I made a simple recording setup using GNU radio:

Can someone help me out about the configuration needed for the recording, so that I can analyze my recording files? (I mainly have my recordings with 10MHz Sample rate, 4MHz bandwidth and on the 2402MHz center frequency)

Thank you in advance.
