Vasil Velichkov 9feb7da807 grgsm_decode: Print frequency or ARFCN message on stderr 
For some yet unknown reasons in travis on Debian testing and Kali rolling
the message gets printed after the burst and decode.sh and decrypt.sh
tests fails because of this.

Instead of filtering this messages in the tests I think it is better
such messages to be printed on the standard error output

README.md

The gr-gsm project

The gr-gsm project is based on the gsm-receiver written by Piotr Krysik (also the main author of gr-gsm) for the Airprobe project.

The aim is to provide set of tools for receiving information transmitted by GSM equipment/devices.

Installation and usage

Please see project's wiki for information on installation and usage of gr-gsm.

Mailing list

Current gr-gsm project's mailing list address is following:

gr-gsm@googlegroups.com

Mailing list is a place for general discussions, questions about the usage and installation. In case of problem with installation please try to provide full information that will help reproducing it. Minimum information should contain:

  • operating system with version,
  • kind of installation (how gr-gsm and its dependencies were installed: with pybombs, from distibution's repository, compiled manually)
  • version of gnuradio (it can be obtained with: gnuradio-companion --version)
  • error messages (in case of pybombs installation they can be obtained after switching it to verbous mode with -v option).

To join the group with any e-mail address, use this link:

https://groups.google.com/forum/#!forum/gr-gsm/join

Development

New features are accepted through github's pull requests. When creating pull request try to make it adress one topic (addition of a feature x, correction of bug y).

If you wish to develop something for gr-gsm but don't know exactly what, then look for issues with label "Enhancement". Select one that you feel you are able to complete. After that claim it by commenting in the comment section of the issue. If there is any additional information about gr-gsm needed by you to make completing the task easier - just ask.

Thanks

This work is built upon the efforts made by many people to gather knowledge of GSM.

First very significant effort of public research into GSM and its security vulnerabilities was The Hacker's Choice GSM SCANNER PROJECT. One of the results of this project was creation of a software GSM receiver by Tvoid - gsm-tvoid - which was was the most important predecessor of gr-gsm and of gsm-receiver from the Airprobe project.

Gr-gsm wouldn't be also possible without help and inspiration by Harald Welte, Dieter Spaar and Sylvain Munaut.

Special thanks to Pawel Koszut who generously lent his USRP1 to the author of gr-gsm (Piotr Krysik) in 2007-2010.
