v2.0.0

This release marks the completion of GSMTAPv3 binary format and decoding improvements.

• SCAT now requires Python 3.10 and above. Python 3.9 and below is not supported anymore.
• SCAT now requires bitstring>=4.0.0. This is to simplify lsb0 mode switch. In the future release, bitstring>=4.2.0 will be required for further lsb0 mode switch simplification.
• Type hints on various places with Pylance's help.
• Qualcomm: LTE MAC DL v49, v50, UL v1 subpacket v3, v5, v8, RACH attempt v1 subpacket v49, v50 support. This improves LTE MAC support on Qualcomm 5G modem.
• Qualcomm: Identification of DIAG secure log public key and encrypted log packet. No support for decryption is planned.
• Qualcomm: QSR4 extended message terse support.
• Samsung: Initial support for 5G SA signaling.

Full Changelog: v1.4.0...v2.0.0

v1.4.0

Time for spring cleanup and release on PyPI. More things will come after updating GSMTAPv3 draft for more metadata.

• You can now install SCAT on the PyPI using pip install signalcat. Note that the distribution name is signalcat, not scat. Check out at https://pypi.org/project/signalcat/
• SCAT: Use exit code 1 on failure by @idugan100 in #103
• Qualcomm: add ML1 meas database update support by @jnunez101 in #104
• Qualcomm: use more bitstring to avoid shift operations
• Samsung: fixed on LTE PHY cell info and other cell measurements
• Samsung: support for ICD 9.0 (tested with Pixel 9)

Full Changelog: v1.3.0...v1.4.0

SCAT 1.3.0

A stop-gap release before finalizing GSMTAPv3 specification, hopefully at OsmoDevCon 2024. This release contains some important changes.

• Layer selection support - MAC layer in Qualcomm is now included in the support, PDCP is not thoroughly tested.
• New dependency on bitstring. Note that SCAT utilizes lsb0 mode which is first included in 3.1.7 and officially supported from 4.0.0+. Most Linux distros do not package the recent version of python3-bitstring yet, I recommend installing bitstring and SCAT through pip for optimal experience.
• Qualcomm: the device timestamp won't be included in the GSMTAP header. As this was included previously as an hack to the GSMTAP header, as a consequence, PCAP(NG) files generated with SCAT <= 1.2.0 will be incompatible with the future Wireshark releases. A conversion tool will be provided after finalizing GSMTAPv3 format.
• Qualcomm: Add new NR RRC OTA packet version 0x13, 0x17 + SCell version 0x30003 + MM State version 0x30000 to support S23 Ultra and S24 Ultra by @peacey in #96
• Samsung: Always use UTC for sdm timestamps by @handymenny in #95
• Samsung: Support for ICD 9.0
• Samsung: Support for Trace/ILM item table (no Trace/ILM items are supported yet)

The release is also available at Test PyPI repository: https://test.pypi.org/project/scat/1.3.0/

SCAT 1.2.0

• Introduce libscrc as optional dependency, and turning off CRC check (#85)
• Qualcomm: add option to print a hexdump of LTE/NR CA combo information (to be used by external tools)
• Qualcomm: decode some 5G DIAG items
• Qualcomm: Decode VoLTE DIAG items
• Samsung: Change to ICD version based approach for baseband detection
• Samsung: Enable GSM and 3G items on the mask
• Samsung: Decode VoLTE DIAG items (S.LSI stack only, not available for Galaxy devices)

This release is also available at Test PyPI repository: https://test.pypi.org/project/scat/1.2.0/

SCAT 1.1.0

• Revert USB dev/bus to base 10 which caused some confusion
• Add combined output feature to see stdout as libosmocore log
• Qualcomm: Implement 5G NR preliminaries
• Qualcomm: add SIP log items
• Samsung: Implement 2G, 3G measurements
• Samsung: add SIP to signaling

SCAT 1.0.0
