Hi I have the bladeRF and I am trying to collect some GSM data.
I have run airprobe_bladerf.grc and airprobe_rtlsdr.grc and I get the gui and I can see the 'wave' appear so I know my bladeRF is responding.
I don't get a stream of data appearing in my terminal however, and I dont see anything in wireshark. I think I have a base frequency at 960Mhz, but I was wondering if there is a clear way of knowing that it has found a frequency or not, so it is easier to know whether something is not working as expected, rather than just 'its not getting any data'

Thanks

I am using a customized variant of airprobe_file with a recorded file of a bts with non-combined channel config.

In GRC, i have two ctrl channel demapper + decoder, one for TS0 and one for TS1.

The demapper config of the TS0 demapper is
timeslot_nr: 0
starts_fn_mod51: [2,6,12,16,22,26,32,36,42,46]
channel_types: [BCCH,CCCH,CCCH,CCCH,CCCH,CCCH,CCCH,CCCH,CCCH,CCCH]

and the config for TS
timeslot_nr: 1
starts_fn_mod51: [0,4,8,12,16,20,24,28,32,36,40,44]
channel_types: [SDCCH, SDCCH, SDCCH, SDCCH, SDCCH, SDCCH, SDCCH, SDCCH,SACCH,SACCH,SACCH,SACCH]

where BCCH = 1, CCCH = 2, SDCCH = 8 and SACCH = 136

If both demappers are enabled, i have the following issue:
Some bursts of TS1 are assigned the gsmtap sub_type (Channel type in wireshark) CCCH instead of SDCCH or SACCH for some reason. If the demapper for TS 0 is disabled, the bursts are assigned the correct channel type.

It looks like those bursts were handled by the wrong demapper despite the fact, that the gsmtap header is assigned the correct timeslot.

Hi All,
I'm rather new to the Linux environment so bare with me. I decided to go the Gqrx PPa route to install gnuradio. When I try to make gr-gsm, I get several errors indicated that the cmake checklist can't find gnuradio and dependencies. Could someone give me exact instructions on how to set the path for gnuradio and cmake modules? Here's the error output:

-- Build type not specified: defaulting to release.
-- Boost version: 1.55.0
-- Found the following Boost libraries:
-- filesystem

CMake Warning at CMakeLists.txt:92 (find_package):

but CMake did not find one.

Could not find a package configuration file provided by "Gnuradio" with any
of the following names:

GnuradioConfig.cmake
gnuradio-config.cmake

Add the installation prefix of "Gnuradio" to CMAKE_PREFIX_PATH or set
"Gnuradio_DIR" to a directory containing one of the above files. If
"Gnuradio" provides a separate development package or SDK, be sure it has
been installed.

Hi @ptrkrysik,

I'll keep spamming you with issues for a while :)
We already talked about wrapping the universal control channel demapper.
The issue is straight-forward, I just created 3 Blocks, where I hide the params starts_fn_mod51 and channel_types, and set them to values depending on their usage. The params just go to universal_ctrl_chans_demapper as before.

I have made 3 of them:
gsm_bcch_ccch_demapper (BCCH + CCCH demapper)
gsm_bcch_ccch_sdcch4_demapper (BCCH + CCCH + SDCCH/4 demapper)
gsm_sdcch8_demapper (SDCCH/8 demapper)

What do you think about the naming ?

Hi,

I have followed your instructions from a base system working with the old airprobe and while trying to use gr-gsm the error Im pasting below started to appear, I have done a clean install and install using pybombs of the packages you specify but the error still appear. Any idea of whats going on? rtl_sdr seems to be working fine.

The machine is the Offensive Security image of Kali Linux 1.1.0, where all the packages were up to date as of about 11 pm Sunday May the 3rd 2015. I allocated 8 gb of memory and 2 cpu cores, because the build failed earlier with the default 2gb, saying the virtual machine had run out of memory.

I saved all my inputs and outputs from this session if they are necessary. I can also post the output of any logs if needed.

Hello, whenever I start airprobe_rtlsdr.py it opens, but the spectrum doesn't run, and it says it cannot find any compatible devices, due to gnuradio error code 528. I did not install this via pybombs.

Could not compile under OSX without changing
decryption_impl.cc

• bool uplink_burst = (be16toh(header->arfcn) & 0x4000) ? true : false;
  +bool uplink_burst = ((header->arfcn) & 0x4000) ? true : false;
  bursts_printer_impl.cc
  • frame_nr = be32toh(header->frame_number);

Any plans to work on receiving other than 0 TS, decode & decrypt ?
I would like to contribute.

The assert macro in lib/receiver/assert.h throws a type called Assertion but that type is not defined anywhere in the code.

Your code references scipy.signal.chirpz, which I can't seem to find anywhere. Is this a custom extension to scipy, or?

Get the following on make:

I just installed Parrot Security OS, which based on Debian, and use MATE desktop environment.
After install gr-gsm using pybombs, and run airprobe_rtlsdr.py, it says:

What's the problem? Is it because the MATE desktop env? Can it be solved?
BTW, gr-gsm runs OK on my kali.

I would like to easily scan a frequency range for C0s, and extract the most interesting parts of the system information messages

I am aware of the system information extractor, which I probably would extend to extract more information. But what is the Gnuradio-way to iterate through the channels ?
Before I start reinventing the wheel, can this already be done using some default block ? Scanning a frequency range with given steps sounds pretty common to me

Dear all,

I'm trying to implement real time channel hopping for gr-gsm. Here are some approaches that I considered:

• Capture a wide portion of the spectrum, channelize using the Polyphase Channelizer block and then parse all channels simultaneously similar to how it is done in this project: https://github.com/BogdanDIA/airprobe-hopping. The disadvantage of this approach is that doing this in real time is very expensive, and in my opinion infeasible. Could be handy though when decoding from a file instead of real time.
• Parse an Immediate Assignment, calculate the hopping sequence and "follow" it in the same way an ordinary phone would. Currently I have a basic implementation that does this by parsing the Immediate Assignment and communicating the frequency to the Source block over Unix domain sockets. However, I'm not sure whether this is fast enough considering the switch must happen in 1ms.

In any case, I'm currently stuck with parsing the first hop to a SDCCH channel. I tried using the TCH/F demapper from this branch but I'm not getting any data in Wireshark. I was expecting to see some control data or occasional packets from phones hopping to the channel in question. Is decoding the SDCCH already supported? If not I would be happy to help :).

Hi,
I've been using gr-gsm for a while now on E4000 based dongle and it's great, however when I'm looking at packets in wireshark every single one of them has signal level equal to 0 in GSM TAP header. Is that intended? (NSR values range from 220 to 228)

Hi, all dependencies are installed, along with gnuradio 3.7.5, though I'm getting this error when trying to make:

$ sudo make

Any thoughts on how this could be fixed?

Hi @ptrkrysik,

as mentioned in an other conversation, i started an implementation of a demapper block for TCH/F.
I orientated the implementation very much on your universal_ctrl_channel_demapper.

Here some of the cornerstones of my approach:

• The demapper is not as general as universal_ctrl_channel_demapper, i dont built any configuration options in. So one cannot configure the channel types in the 26-multiframe, there are just 2_3_4 bursts plus 1 SACCH/TF burst, which are mapped according to the specification. I didnt see any use for it in case of TCH. However, i didnt consider so far how the behaviour is specified for hopping channels.
• The demapper has two different output ports, one for TCH bursts, and another one for ACCH, so we can send the bursts the right decoder only.
• Currently i check if the stealing bits are set for TCH bursts, and if so i consider them as FACCH, and the bursts are sent to the ACCH port. The check is rather simple, if one frame has stealing

I have only tested this approach for correct ACCH messages (which looked fine so far), i wanted to test it with an TCH decoder as well, but this will take me some more time.

So, what do you think ?

Hi,

Im trying to analyze traffic from my mobile but I see that gr-gsm doesn't have the option like airprobe to analyze other timesloys than 0. Can this feature be included?

I have tried to run the old airprobe for this while I have gr-gsm fully functional but is complaining about the gsm library saying that module doesnt have the attirbute receiver_cf.

Im stil understanding the code so I can try to make some contributions to this project but Im still really new to this so Im just trying to test it as much as I can and provide the feedback I can.

Thanks in advance.

In extract_system_info the arfcn is used as id for the chan_info, however gsmtap header->arfcn is always zero in my case, also in Wireshark.

Does this work for you, e.g. do you see valid arfcn values in the gsmtap header ?

Hello everyone,
Even though this was my first time install with pybombs I somehow completed with the help of @ptrkrysik but after successful install I couldn't run gr-gsm with command:
airprobe_rtlsdr.py

it is giving this error output:

Please someone tell me how can I solve this issue ? I have already tried removing osmosdr package and reinstalling it.

hi, I am now learning the SDR and trying to experiment on GSM. Could you tell me how it works in depth, is it a active system that sends the silient SMS or a passive system just listen to GSM network only ?

Thanks in advance

Different versions of gnuradio companion generate python files that may be incompatible between different GNU Radio versions. It would be best to compile python files on user machine, for whatever version of GNU Radio (starting from 3.7.3) he has.

I'm looking for someone who know how to do this with use of cmake. There is a file taken from GNU Radio which is in gr-gsm/cmake/Modules/GrMiscUtils.cmake. It has GRCC which was suited for GNU Radio (although it is not really used in GNU Radio) but not third party projects. I've tried to adapt it to gr-gsm case but it caused more problems than it solved. If you know how to write a CMAKE rule compiling GRC files - please help.

Hi everyone,

I'm trying hard to make gr-gsm work, but i have an issue when executing the command: sudo ./pybombs install gr-gsm.

Hi everybody,

I finnaly installed gr-gsm, but now i have an issue when executing the "airprobe_file.py", i type this command:
"airprobe_file.py --samp-rate=1M --fc=940M capture.cfileC

Here is the error log:

Hi there, just tried installing using:

sudo ./pybombs install gr-gsm

When I go to run airprobe_rtlsdr.py getting the error:

Traceback (most recent call last):
File "/home/steveswallow/target/bin/airprobe_rtlsdr.py", line 19, in

ImportError: No module named grgsm

Same thing with airprobe_file as well.

My python version is Python 2.7.6.

Cheers

Hi @ptrkrysik,

i would like to contribute to gr-gsm, and have a few questions:

• Do you prefer having an issue for every pull request ?
• Do you prefer one pull request for every bug fix / feature / ... or an aggreation into one pull request
• Have any limitations / rules / style guides ?
• Do you support issue assignments to users ? For example, i recently implemented a demapper for TCH/F, and will implement the corresponding decoder in the next weeks. So if someone else is working on this feature, i would spend the time one something else.

Hi,

I have tried to use airprobe_file.py with the usual example for the old go.sh and with a couple of test captures I did but nothing appears on wireshark listenning on lo, maybe im missing something?

This is the command Im running:

airprobe_file.py --samp-rate=1M --fc=941.8M -i ~/airprobe-old/gsm-receiver/src/python/capture_941.8M_112.cfile

CPU spikes for a little time and then it just stops doing nothing.

Thanks in advance.

I have installed gr-gsm on my ubuntu, it works well. now I want to put it into my raspberrypi. I know using pybomb to install it is a easy way, but pybomb needs to download and recompile everything, which it is too slow for me. I have installed compiled gnu-radio into the PI, which is much quicker installation. In my previous gr-gsm installation, I have also installed a gnu-radio on my ubuntu, but pybomb still downloaded and recompiled.

My question, if I have installed some precompiled package, how do I bypass these installed package through pybomb, or I can just install all the needed package myself manually and install gr-gsm at last

Hi @ptrkrysik,

today i did a quick&dirty integration of airprobe's approach to TCH decoding.
Did a quick test with a GSM-FR capture sample, did work well. Voice was very well recognizable, but not very good quality. Probably because it is just FR.

So, here my thoughts about the decoder:

• Feature set:
  • one port in with bursts from demapper
  • one port out, if we handle the whole FACCH in the TCH-decoder, as in airprobe
  • select file for speech output
  • select coding
• reuse existing code
  • should we use the more recent code of OpenBTS, or the one from airprobe ? The one from airprobe is already reduced to what we need. According to the manual, they still only support GSM-FR. I tend more to use the airprobe version.
  • should we refactor the code we reuse, to fit more to gr-gsm, or try to integrate the code without modification for maintenance reasons (update source from OpenBTS). I would rather refactor, what do you think ?

Currently decoding SDCCH channels or TCH channels requires editing of flowgraphs in gnuradio-companion.
To increase usability addition of parameters for:
-configuring logical channels that user want to get from different timeslots,
-supplying Kc session key,
is needed.

Hi all,

I've reports that gr-gsm doesn't work with Fun Cube dongle. I would greatly appreciate confirmations from other sources and captures of raw GSM signal, sou I could debug the problem.

Here is samples with AMR HR

Hi,
I've the following error when running this command: sudo ./pybombs install -v gr-gsm

-- Dependency LIBUSB_FOUND = FALSE
CMake Error at cmake/Modules/GrComponent.cmake:75 (message):
user force-enabled gr-fcd but configuration checked failed
Call Stack (most recent call first):
gr-fcd/CMakeLists.txt:35 (GR_REGISTER_COMPONENT)

I checked if libsub was installed on my computer and i can see some files like "libusb-0.1-4_2%3a0.1.12-25_amd64.deb" in /var/cache/apt/archives, so i guess libusb is installed.

Also i added "libusb" to gnuradio.lwr depends...I'm stuck now. Your help would be great.
Thanks
Aymeric

I built gr-gsm clean yesterday with no problem. I do a git pull today and this is happeneing. I can't find anything in the git logs that seem sresponsible however.

I am on Ubuntu 14.04 with gnuradio 3.7

There are a lot of functionalities that are already implemented in other projects on different layers of GSM protocols. Most advanced among them are Osmocom and OpenBTS. I'm therefore starting discussion here to create wish-list with functionalities that are implemented in them that should be imported to gr-gsm and to find out how to do such imports.

I havent tried to decode multiple Channels with single GSM block but would like to know if we are getting frame number on CX wrt hopping channel.

Also what about timeslot details. are we able to get timeslot details on CX wrt supplied channel

Hi,

I'm still trying to install gr-gsm and i've another trouble with the " sudo ./pybombs install -v gr-gsm" command.
Indeed there is an error concerning cheetah (which i installed, and for which i changed the PYTHONPATH).

I don't know what to do now, any idea ?

Thx

Aymeric

Dear Piotr

I am testing your implementation on DCS, PCS it used to work before but latest build is not working

Offer for someone who wants to get taste of gr-gsm development but don't want to start with something overly complicated:

Currently storing of data is done by saving/reading raw signal to/from a file with use of gnuradio's file sink/source blocks. It is good method for testing the receiver, but it takes too much space during normal operation. Also there are many situations in which someone might want to process bursts multiple times but focussing on different part of the data each time. There is no need then to process the signal on each run to get bursts.

The solution is to add burst sink and source. Sink will have one message input (messages containing bursts) and will store bursts to a file (it's name will be given as a parameter). Source will read bursts from files and will send them through a message output.
