To properly decode GSMTAP packets generated by SCAT, Wireshark 2.6.0 or above is required.
For older Wireshark releases, we are providing a Wireshark Lua plugin to extend the GSMTAP dissector.
The Wireshark plugin is required to dissect LTE MAC and PDCP packets generated by SCAT version 1.3.0.
The Wireshark plugin is required to dissect LTE MAC and PDCP packets generated by SCAT version 1.3.0, and NR RRC/NAS-5GS packets.

**Warning:** NR RRC/NAS-5GS messages are only available through GSMTAPv3 which is **[work in progress](https://gitea.osmocom.org/peremen/gsmtapv3)**.
SCAT master uses GSMTAPv3 draft version only for NR RRC/NAS-5GS, and the definition of GSMTAPv3 may change in the future.
SCAT does not guarantee data compatibility of GSMTAPv3 packets **until it is finalized**.
Therefore, please also keep the QMDL/SDM files if you need to preserve 5G signaling messages for future usage.
