Sniffing capability is based on Scapy framework, so it should be installed in order to run this tool. Please also note, that sniffing requires root access. For details, see: https://github.com/secdev/scapy https://scapy.readthedocs.io/en/latest/ Usage example: sudo ./trx_sniff --frame-count 30 --timeslot 2 -o /tmp/bursts This command will capture 30 frames on timeslot number 2, and write them to a binary file. The format of this file is based on TLV (Tag Length Value), that wraps each burst: ... |-TAG (byte)-|-LEN (byte)-|-BURST (LEN bytes)-| ... TAG 0x01 - a message coming from L1 to TRX TAG 0x02 - a message coming from TRX to L1 Change-Id: I6e65e1d657574cc3e67bc7cdb1c01ef6bf08ecde http://cgit.osmocom.org/osmocom-bb/commit/?id=32462cfd62a25a461d36845e546f1… commit 32462cfd62a25a461d36845e546f150bd8ca0e97 Author: Vadim Yanitskiy <axilirator(a)gmail.com> Date: Sat Jan 20 16:44:19 2018 +0600 fake_trx/burst_send.py: indicate actual burst source Change-Id: I7e45996f4a7a2aacc962ff9b65107c6b04e7bf68 ----------------------------------------------------------------------- Summary of changes: src/target/fake_trx/README | 6 + src/target/fake_trx/burst_send.py | 2 + src/target/fake_trx/trx_sniff.py | 318 ++++++++++++++++++++++++++++++++++++++ 3 files changed, 326 insertions(+) create mode 100755 src/target/fake_trx/trx_sniff.py hooks/post-receive -- The Open Source GSM Base Band stack
