Hi @antiuniv,

i installed parrot

Which version?

and grgsm but if runnug grgsm_scanner i have this erro

How did you install gnuradio - from the apt repository or using pybombs? How did you install gr-gsm - manually, from the apt repository or using pybombs? What SDR device do you use?

To get some more output open apps/grgsm_scanner and comment out the following lines

320             os.dup2(null_fds[0], 1)
321             os.dup2(null_fds[1], 2)

then reintsall, test again and provide the full output.

See also #426, #336 and #273

[antiuniv]

version Parrot-security-4.1

i install apt-get install gr-gsm

[velichkov]

i install apt-get install gr-gsm

Could you list all commands that you have used?

Also answer the question about the SDR device and provide the full output after commenting out lines 320 and 321.

After commenting them you need to reinstall by executing make install in the build directory.

[velichkov]

Also try plugging the RTL dongle in a different USB port

The multiple 'O' indicates buffer overflows, which means that host is not able to read the data from the RTL fast enough and the buffers get full.

Are you running it in a Virtual Machine? Provide the full output of lsusb and cat /proc/cpuinfo

Try running it with smaller sample rate

grgsm_scanner -s 0.8e6
grgsm_scanner -s 1.2e6

and provide the full output of both commands.

Maybe this Atom processor is not powerful enough. If you have another machine with more powerful CPU try on it.

Have you tried with a smaller sample rate ?

I don't understand what you mean

[antiuniv]

The aplication grgsm_scanner were working on the same machine

[velichkov]

Sorry I somehow still don't get it. I've asked if you could try on a more powerful machine (if you have one) and if you have tried with a smaller sample rate and you respond with "The aplication grgsm_scanner were working on the same machine".

[antiuniv]

Thank you. I will try it on another machine

[velichkov]

Please try with a smaller sample rate

There is no such version 4.4.0 on the parrot website Could you give me a link to the version you have installed?

Compared to your previous installation the only different thing is the parrot version, is that right?

grgsm_scanner and grgsm_livemon worked good

When testing grgsm_scanner did you specify smaller sampling rate and does it work with the default 2M ?

This is the Linux's kernel version and not the Parrot OS version. It seems you are running an older version (probably 3.11) as the 4.2 version is with kernel 4.18.6. Also you are running the 32bit version (i686).

I doubt this is the problem as it specify only how many CPUs will be used during compilation and does not make any difference when executing the compiled programs.

Ok, as suspected you are running 3.11 and not 4.1 as you've told me in https://github.com/ptrkrysik/gr-gsm/issues/432#issuecomment-418711702 . You could try to upgrading your system sudo apt full-upgrade and risk breaking grgsm_scanner or keep it as is.

[duvaldt]

I have the same problem here, using Ubuntu and have tried with both the compiled version and distributed packages.

I can tune in on radio stations usin gqrx, but I have never seen anything using grgsm_scanner or grgsm_livemon. When grgsm_livemon starts, I get no output in the terminal.

If I use device 7 instead of 0 nothing will work, but if I use 7 I can listen to the radio. When I use grgsm_scanner, it says it's using device 0, and a "Generic RTL... device". Unable to specify anything else though.

[velichkov]

Hi @duvaldt,

getDeviceList : Available input devices: 0 : "Realtek RTL2838UHIDIR SN: 00000001" 7 : "Generic RTL2832U OEM :: 00000001"

How many RTL SDR devices do you have connected to your system - one or two?

I'm not familiar with gqrx project but it seems they are using gr-osmosdr as well.

When running grgsm_scanner try to specify the rtl device in the --args parameter. Try the following

grgsm_scanner --args=rtl=0
grgsm_scanner --args=rtl=1
grgsm_scanner --args=rtl=7

If you have multiple RTL devices you could try to change their serial numbers as well with rtl_eeprom -d 0 -s 00000002

https://ptrkrysik.github.io/#capturing-gsm-downlink-and-uplink-with-multi-rtl https://osmocom.org/projects/gr-osmosdr/wiki#RTL-SDR-Source

[duvaldt]

Hi,

I only have one device connected, that is why it's so strange =/

I've tried changing it to something else but nothing other than 0 will work.

Could it be possible that there are some problems with the hardware? I can listen to the radio but I never find any GSM-stations.

Best regards, Mattias

Hi @duvaldt https://github.com/duvaldt,

getDeviceList : Available input devices: 0 : "Realtek RTL2838UHIDIR SN: 00000001" 7 : "Generic RTL2832U OEM :: 00000001"

How many RTL SDR devices do you have connected to your system - one or two?

I'm not familiar with gqrx project but it seems they are using gr-osmosdr https://github.com/csete/gqrx/blob/master/src/qtgui/ioconfig.cpp#L237-L242 as well.

When running grgsm_scanner try to specify the rtl device in the --args parameter. Try the following

grgsm_scanner --args=rtl=0 grgsm_scanner --args=rtl=1 grgsm_scanner --args=rtl=7

If you have multiple RTL devices you could try to change their serial numbers as well with rtl_eeprom -d 0 -s 00000002

Yes, it's really strange and I don't know why gqrx reports two devices.

I've tried changing it to something else but nothing other than 0 will work.

Could you upload somewhere (google drive, dropbox, pastbing ...) the whole debug output when you start it with 0 and 1.

I can listen to the radio but I never find any GSM-stations.

Have you tried a different band? Maybe there is no any GSM cells in the default GSM900 band where you live.

-b BAND, --band=BAND  Specify the GSM band for the frequency. Available
                        bands are: GSM900, DCS1800, GSM850, PCS1900, GSM450,
                        GSM480, GSM-R

[duvaldt]

Thanks! I'll give it a try =)

Do you know if it's possible to get debug messages with the prebuild distribution package?

No, I've added the --debug flag recently and it's still not available in the packages. You have to comment out the following two lines in /usr/bin/grgsm_scanner

320             os.dup2(null_fds[0], 1)
321             os.dup2(null_fds[1], 2)

[velichkov]

When you start gqrx is shows the following dialog box where you need to select a device

and when you select one the Device string is changed automatically.

What is the Device string when you select device #7 and what is when you select #0?

[duvaldt]

Good idea! Device 0: available=Yes,driver=rtlsdr,manufacturer=Realtek,product=RTL2838UHIDIR,rtl=0,serial=00000001,soapy=2,tuner='Rafael Micro R820T' Device 7: rtl=0

Thanks again!

soapy=2

Most probably the device is found twice because it's detected by both soapy (device #0) and directly by the rtl-sdr (device #7). In my opinion grgsm_sacnner --args=rtl=0 should work so try scanning all bands and always wait until it finishes as it usually takes some time. You could also try scanning with kalibrate-rtl

How did you install gr-osmosdr and which Ubuntu version do you use?

Thanks, I'll give it a try again!

Everything looks good here.

FATAL: Wrong rtlsdr device index given.

This error is more then expected as as you have only one RTL dongle.

Does this give you any clues? https://pastebin.com/5VAtC3Hj

[R82XX] No valid PLL values for 1807525000 Hz! r82xx_set_freq: failed=-1

I don't have much experience with the RTL devices but this doesn't look good. It fails to tune to the requested frequency, maybe these dongles do not support 1800MHz.

Have you tried to search with kalibrate-rtl?

Does your dongle support bias tee? There was a report that it has to be disabled.

[milankubin]

Interesting, I'm running into the same problems with exactly the same dongle. The dongle is certainly limited. kalibrate gives me at least a result :)

Hi @milankubin,

Interesting, I'm running into the same problems with exactly the same dongle.

What is the exact problem you are having as at least 3 problems are being discussed in this issue? Do you have a suitable antenna attached to the device? What OS do you use and which version? How did you install gnuradio and gr-gsm and which versions?

kalibrate gives me at least a result :)

kalibrate-rtl is known to report false positives.

kal: Scanning for GSM-850 base stations.

Where do you live?

The GSM-850 band is used in North America and in USA there is no longer GSM network in this band as AT&T stopped their 2G network back in 2017.

For the higher GSM bands (1800 and 1900 MHz) you need RTL dongle with Elonics tuner like this one or another device that supports these frequencies.

Sorry for reviving this ticket, but I stumbled upon it search for the issue I'm having.
