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 🙂

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

You need [gr-limesdr](https://github.com/myriadrf/gr-limesdr) blocks installed.

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

Hi smtguide,

can you remember how you fix the "Tune Rx Filter: MCU error 2 " Error ?
