gnuradio error

[nocomp]

hi folks, first of all thxx for this great tool i used to have working, but no idea what i ve did, almost spend a day to get it back on rails with no luck. you are my last chance here is the situation: i ve installed on last kali version (used to work) using apt-get and now when i launch it i get:

nocomp@8uR34ud3sL1c0rn35:~/tools/sdr/gr-gsm$ grgsm_scanner Traceback (most recent call last): File "/usr/bin/grgsm_scanner", line 24, in from gnuradio import blocks ImportError: No module named gnuradio

so i ve pulled the git and when i try to build it i get for cmake ..

CMake Warning at CMakeLists.txt:135 (find_package): Found package configuration file:

/usr/lib/x86_64-linux-gnu/cmake/gnuradio/GnuradioConfig.cmake

but it set Gnuradio_FOUND to FALSE so package "Gnuradio" is considered to be NOT FOUND. Reason given by package:

Gnuradio could not be found because dependency Volk could not be found.

CMake Error at CMakeLists.txt:150 (message): GnuRadio Runtime required to compile gr-gsm

i ve uninstall and reinstall gnuradio gr-gsm many times still same error :'(

grc is in /usr/lib/python3/dist-packages/gnuradio/grc

and here are my paths:

all kind of helps are welcome, receiving my limesdr in 2 days and my whole world is broken... #HELPPPPPPPPPPPPPPPPPP

thxx for your time

Hi @nocomp,

first of all thxx for this great tool i used to have working, but no idea what i ve did, almost spend a day to get it back on rails with no luck. you are my last chance here is the situation: i ve installed on last kali version (used to work) using apt-get and now when i launch it i get:

It's quite typical for Kali (and other rolling distributions) something that have worked yesterday to no longer works today.

In Debian Testing and Kali they have updated gnuradio to 3.8 but still have not updated all dependent packages.

so i ve pulled the git and when i try to build it i get for cmake ..

CMake Warning at CMakeLists.txt:135 (find_package): Found package configuration file:

We are working on adding support for gnuradio 3.8 in #475. Try building from maint-3.8 branch from my fork and have a look at Kali.docker that is used in our travis builds

[nocomp]

hi thx a lot for your reponse i check that in a hour thxx again for your time

As I said in my previous message you need to checkout and build maint-3.8 branch from my fork.

oh i thought i just had to git clone your repo and then go to the install process like the on in installation page. do you have a tutorial i can follow? thxx for your time

You need to install liborc-dev and not liborcus-dev nor liborc-0.4-0. You could find the full list of packages in the docker file.

From the top gr-gsm directory you need to execute

docker build -f tests/dockerfiles/Kali.docker .

Note that there is a dot (.) at the end of the command, you need it.

hi thxx a lot for your reply i ve been able to compile following your advice, but when i run it, i get this module error:

nocomp@8uR34ud3sL1c0rn35:~/tools/sdr/gr-gsm/build$ grgsm_scanner Traceback (most recent call last): File "/usr/local/bin/grgsm_scanner", line 33, in import grgsm ModuleNotFoundError: No module named 'grgsm'

; what did i do wrong?

compilation worked like a charm with your fork, well done! thxx for your time cant find using pip or apt any module named like this

[velichkov]

nocomp@8uR34ud3sL1c0rn35:~/tools/sdr/gr-gsm/build$ grgsm_scanner Traceback (most recent call last): File "/usr/local/bin/grgsm_scanner", line 33, in import grgsm ModuleNotFoundError: No module named 'grgsm'

You need to add /usr/local/lib/python3/dist-packages/ to PYTHONPATH, in your shell execute

export PYTHONPATH=/usr/local/lib/python3/dist-packages/:$PYTHONPATH

or to make it permanent add this to your shell profile (~/.bashrc or ~/.bash_profile)

That's needed because of this debian's patch

[nocomp]

yeaaaaaaaaaaaaaaaaaaaaaaaaaa works like a charm, thank you so much:!!!! the docker installed work, but wont use it, need to fgure out how clean that in order to get some hd space. thx again for your time, truelly appreciate. next challenge: decode sms :))

[velichkov]

but wont use it, need to fgure out how clean that in order to get some hd space.

Run docker ps -a and then for every CONTAINER ID or NAMES run docker rm 895e7a7b445d gnuradio-ubuntu-16.04 ....

Then run docker images and for every IMAGE ID run `docker rmi c3e52da505c6 ...

next challenge: decode sms :))

hi, just find out that grgsm_scanner is not working no error message, just nothing showin up one you press enter (no hardware detection either as you can have with livemmon)

just reinstalled and now it works, just takes a bit of time thxx @velichkov for your priceless time

[nocomp]

in fact there is an issue (sorry again) when i grgsm_scanner with your fork version i get only one result if i grgsm_scanner on another computer that has it preinstalled i get 14 results

any idea why?

thxx for your help

[velichkov]

any idea why?

Do you use the same SDR device with the same antenna on both computers? What are the hardware specs of the two computers - CPU, RAM, USB port types, etc...?

[nocomp]

hi, yes same sdr device and same antenna and same computer lenovo x280 in multiboot your fork on kali boot, and the normal version on HamOS 8gb ram USB 3 ssd hd i3 8th gen

[velichkov]

and the normal version on HamOS

What is the exact version? What SDR device do you use and how is connected to the host - USB 2/3 or ethernet?

[nocomp]

hamos runs 0.42.2-1+b2 i ve used a standard nooelec blue rtlsdr to usb3

[velichkov]

i ve used a standard nooelec blue rtlsdr to usb3

NESDR Mini 2 or NESDR Mini 2+ ?

Run the following commands on both HamOS and Kali, wait them to complete, upload the full output somewhere and provide a link. Do not copy-past the whole output here as the long posts makes the discussion hard to follow.

lsusb -d 0bda:2832 -v
lsusb -d 0bda:2838 -v
timeout 1m rtl_test -p
timeout 5m rtl_test -s 2000000

Could you try compiling from source and testing grgsm_scanner from the master branch on HamOS? If there is a regression we need to determine if the bug was introduced between version 0.42.2 and maser or between master an my maint-3.8 branch.

hamos runs 0.42.2-1+b2

Unfortunately this version does not support the --debug flag. As root open /usr/bin/grgsm_scanner with your favorite text editor, comment out lines 320 and 321, run grgsm_scanner as usual, wait it to finish, upload the full output and provide a link to it.

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

Also run grgsm_scanner --debug ... on Kali, and again upload and provide a link to it.

[nocomp]

hi, thx a lot for your time, i ll do that tonite @work atm. thxx again for your help

[velichkov]

8gb ram USB 3 ssd hd i3 8th gen

Dose your CPU support AVX2 or FMA instructions? Provide the output of cat /proc/cpuinfo | grep flags

There is a known VOLK bug (https://github.com/gnuradio/volk/pull/278) and the fix for it is still not merged. The workaround is to set VOLK_GENERIC environment variable to 1.

export VOLK_GENERIC=1

[velichkov]

do i need to add export VOLK_GENERIC=1 in my .bashrc to make it permanent?

Yes, you could add it to .bashrc but then if you care about performance you need to monitor the volk package in the Kali repository and when they release a fixed version you'll need to remove this line.

And again please use our mailing list. Thanks.

many many manyyyyyyyyyyyyyyyyyyyy thanks!!! glad we spoted somethig that wasn t quite right thanks again for your time

[velichkov]

Hi @jsa91,

~# grgsm_scanner -b GSM900 -d [ERROR] avahi_service_browser_new() failed: Bad state

[ERROR] avahi_service_browser_new() failed: Bad state Assertion 'close_nointr(fd) != -EBADF' failed at src/basic/fd-util.c:71, function safe_close(). Aborting.

This seems like either avahi or systemd bug.

Try running both grgsm_scanner and grgsm_livemon_headless with --args=rtl argument.

grgsm_scanner --args=rtl -d
grgsm_livemon_headless  --args=rtl -f 952.6M

and provide the full output if you still see the above errors.

[jsa91]

Hi @velichkov ,

Took you tips from #475 and installed Debian 10 instead. Now running gr-gsm without problems. Thanks anyway.

avahi bad state error was also seen which was eradicated by args argument but invalid source error...what is the reason for that... livemon monitor is running but no gsm data being captured so far

Hi @anandpandey786 Use this command grgsm_livemon_headless --args=rtl -f 952.4M you have missed headless in command.

[anandpandey786]

Thanks for reply I deliberated omitted headless .... wanted to see the pixmap/monitor Every thing is running in my build but despite that gsm data is not visible on monitor tried several frequencies...

Hi @anandpandey786,

avahi bad state error was also seen which was eradicated by args argument

What args did you used to solve the avahi errors?

but invalid source error...what is the reason for that...

I don't know.

livemon monitor is running but no gsm data being captured so far Every thing is running in my build but despite that gsm data is not visible on monitor tried several frequencies...

First try finding a frequency of a nearby C0 BCCH channel using grgsm_scanner and then specify that frequency when running grgsm_livemon. Also make sure there are GSM networks where you live in the bands supported by your RTL device.

Hi velichkov Thanks for your reply .... issue was resolved there was some glitch in my antenna i am using your 3.8maint . regards

Hi,

I'm using a RTL2838 SDR with Ubuntu 16. I followed your installation instructions from the osmo website hyperlink from ptrksky grmgsm github repository to the letter.

Everything works except when I run grgsm_livemon I keep getting 0's displayed.

grgsm_scanner returns no results when scanning all available bands. Kalibrate-rtl RETURNS GSM stations and no other bands. Kalibrate has given me my ppm.

Rtl_test returns no errors in my signals. I have changed sample rates, used VM and a desktop with Ubuntu 16 returning the same results.

What else can I do?

Kalibrate-rtl is known to return false positive results.

Do you have a suitable antenna attached to your RTL dongle? Are you sure that there are GSM networks in the area where you are and in the band you are searching in? In case you are inside in a big building try moving near a window or outside.

In case you live in USA note that AT&T stopped their 2G network in the GSM850 band back in 2017 and for T-Mobile network in the GSM1900 band you need a dongle with Elonics E4000 tuner or another SDR device that supports that band.

Hi @velichkov I am successful in installing grgsm from your maint branch and I am get all BCCH data like MCC,MNC,LAC and some other things, but there is problem when designing simple gui application using tkinter. I am attaching code below

import tkinter as tk import subprocess import shlex

def BCCH(): cmd=["grgsm_scanner","--args=rtl","-b","GSM900"] output= subprocess.check_output(cmd) result=print('>', output)

put result in label

            result['text'] = output.decode('utf-8')

my_gui = tk.Tk() my_gui.geometry('600x600') my_gui.title("Get output inside GUI")

tk.Button(my_gui,text="GET BCCH", command=BCCH).pack()

label for BCCH result

result = tk.Label(my_gui,font=50) result.pack()

my_gui.mainloop()

I am getting excemptions thinking that some files are missing. Exception in Tkinter callback Traceback (most recent call last): File "/usr/lib/python3.7/tkinter/init.py", line 1705, in call return self.func(*args) File "/home/kali/test.py", line 7, in BCCH output= subprocess.check_output(cmd) File "/usr/lib/python3.7/subprocess.py", line 411, in check_output **kwargs).stdout File "/usr/lib/python3.7/subprocess.py", line 512, in run output=stdout, stderr=stderr) subprocess.CalledProcessError: Command '['grgsm_scanner', '--args=rtl', '-b', 'GSM900']' returned non-zero exit status 1.

when I type in command line interface as kal -s GSM900 the output is coming. I think I will get solution. Thanks

[kiransgk1si18lvs04]

When I try adding exclusions.

import tkinter as tk import subprocess import shlex def BCCH(): while True: try: cmd=["grgsm_scanner","--args=rtl","-b","GSM900"] output= subprocess.getoutput(cmd) result=print('>', output)

put result in label

            if not output is None:
                result['text'] = output.decode('utf-8')
    except subprocess.CalledProcessError as exc:
       print(exc.returncode)

my_gui = tk.Tk()

my_gui.geometry('600x600') my_gui.title("Get output inside GUI") tk.Button(my_gui,text="GET BCCH", command=BCCH).pack()

label for BCCH result

result = tk.Label(my_gui,font=50) result.pack()

my_gui.mainloop()

The errors are like this Traceback (most recent call last): File "/usr/local/bin/grgsm_scanner", line 33, in import grgsm ModuleNotFoundError: No module named 'grgsm'

[velichkov]

Hi @kiransgk1si18lvs04,

ModuleNotFoundError: No module named 'grgsm'

Make sure you are running your application with the same python version that gr-gsm and gnuradio was compiled with (most probably python3), add the following as the first line in your scripts.

#!/usr/bin/python3

If it still does not work you may need to add the path where the gr-gsm's python module was installed to the PYTHONPATH environment variable, see https://github.com/ptrkrysik/gr-gsm/issues/480#issuecomment-532305188

P.S. Please next time try using markdown to format your messages as right now they are hardly readable and avoid hijacking unrelated github issues.
