Python-based SIMtrace2 sniffer — drop-in replacement for simtrace2-sniff.
Single dependency (pyusb), auto-reconnect, GSMTAP/PCAP output, library API.
Modules:
protocol.py — SIMtrace2 USB sniffing protocol parser
device.py — USB discovery + SniffSession with exponential backoff reconnect
gsmtap.py — GSMTAP UDP sender for Wireshark
pcap.py — PCAP file writer (LINKTYPE_GSMTAP)
dump.py — hex dump formatters + file output
__main__.py — CLI entry point
Startup script sniff-start.sh handles udev permission checks and shows
install instructions. udev rule uses TAG+=uaccess (systemd-logind ACL).
