User bkerler's gr-gsm fork for GNURadio 3.10 compatibility. Split for DS flowgraphs using bladeRF/SigMF

Dependencies

sudo apt-get install build-essential libtool libtalloc-dev libsctp-dev shtool autoconf automake git-core pkg-config make gcc gnutls-dev libusb-1.0.0-dev libmnl-dev liburing-dev libpcsclite-dev libosmocore18 libosmocore-dev

pip install QDarkStyle qtpy

GNURadio 3.10.12 libosmocore tag v1.12.1 -- Install from source instructions Source and Sink blocks that give most control over bladeRF: gr-bladeRF

*Use these block if the gr-bladeRf doesn't work Source and Sink blocks for generic SDR control. Works with bladeRF: gr-osmosdr tag v0.2.6

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 a set of tools for receiving information transmitted by GSM equipment/devices.

Installation

Pull example GSM Flowgraphs and test data with git submodule update --init

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

Usage of DS scripts

Check ds_examples folder rx and tx for BCCH or TCH. BCCH test data used 1Mhz Fs while the voice file used (100e6/174) MHz. Either python cmd-line or Gnuradio flowgraphs can be used.

• scale_gsm_for_12bit grc/py: Set the Fs of the cfile and adjust which filter to use (create new ones for other signals) to write to SigMF.

• get_bcch_bladerf : Read the BCCH channel for GSM. Uses gr-bladeRF, can view contents with sudo wireshark on Loopback:lo

• get_bcch_osmosdr : Read the BCCH channel for GSM. Uses gr-osmosdr, can view contents with sudo wireshark on Loopback:lo

• get_tch_bladerf : Read the TCH channel for GSM and playsback audio. Uses gr-bladeRF, can view contents with sudo wireshark on Loopback:lo
