grgsm_scanner: no results, kernel driver loops over deattach/reattach #565

Open blackbit42 opened 3 years ago

blackbit42 commented 3 years ago

Hi

I am on Debian 11/amd64 with gr-gsm installed via apt. kalibrate-rtl works as expected. grgsm_scanner seems to be stuck in a loop. Or is this behavior expected? At any rate, it produces no results.

I am not sure how to debug this.

$ grgsm_scanner --args=rtl=0 -b DCS1800 -v -g 40 --debug

grgsm_scanner seems to be stuck in a loop. Or is this behavior expected?

The loop is expected as it scans over all frequencies of the selected band -b DCS1800. The process is not fast so wait patiently until it finishes.

Found Elonics E4000 tuner

You have an Elonics tuner so the DCS1800 band should be supported. Just make sure that in the country and region where you live there are active GSM cells in this band.

In case you are testing inside of a big building try moving near a window or outside if possible.

blackbit42 commented 3 years ago

Indeed, it finishes after 3 minutes. I ran into this issue, but that was easy to overcome.

However, no results are being printed. I know there are multiple DCS1800 operators here though. What could be wrong?

know there are multiple DCS1800 operators here though.

How do you know that?

What could be wrong?

Does it find cells in the default GSM900 band? Do you have a suitable antenna? Have you tried near a window or outside? Have you tried with a different gain setting?

  -g GAIN, --gain=GAIN  Set gain [default=24.0]
