GRGSM LimeSDR-Mini Ubuntu 18.04 LTS

#1

Am trying to get LimeSdr Mini to work with grgsm_scanner on Ubuntu Server is impossible to install UHD drivers anymore does anymone has an image of working LimeSdr mini with GR-GSM??

#2

Afraid not, but we are working on a version which uses the gr-limesdr blocks so that you don’t need to have UHD and SoapySDR plus plug-ins in the middle.

I found an old Iso Image that has all prebuilt already with 16.04 LTS but is ISO and cannot rely on that is there any other way around to SCAN ARFCN with lime SDR? is working perfectly with a old RTL-SDR we bought Lime-SDR to update our system and we can’t manage to get any results it’s such a shame.

I think in theory it should work, but I didn’t have much luck when I tried and there is no point in us investing time in trying to get this working via gr-osmosdr — a route which will always be far more fragile — when there is work to use it via a gr-limesdr source.

Of course, everything is open source and so you are free to debug and fix it yourself :slight_smile:

So the gr-gsm fork here uses gr-limesdr:

It’s just the actual script that was modified, so if you already have a build, you should be able to just drop the modified version in:

Hi again Andrew,

I tried with your methode but still didn’t manage to get limesdr mini with grgsm_scanner. you have any installtion procedure for limesdr mini to work with grgsm_scanner?

When I replace with your file grgsm_scanner, I get the following message:

user@ubuntu:~$ grgsm_scanner
linux; GNU C++ version 7.3.0; Boost_106501; UHD_003.010.003.000-0-unknown

Segmentation fault (core dumped)

After some more tried getting:

user@ubuntu:~$ grgsm_scanner
linux; GNU C++ version 7.3.0; Boost_106501; UHD_003.010.003.000-0-unknown

Traceback (most recent call last):
File “/usr/local/bin/grgsm_scanner”, line 37, in
import limesdr
ImportError: No module named limesdr

#7

Could that have to do with anyting that Board is Faulty??

#8

You need gr-limesdr blocks installed.

#9

Could u provide some help regarding limessr blocs?

#10

You need to install them, along with gr-gsm and its dependencies. If this doesn’t help, you’ll need to be more specific.

Ok I installed Modules for GNU Radio they appear in GNU RADIO but now when I get the following error:
