Wrong length of qcdiag.log.nr_rrc_frequency field in Wireshark plugin diag_nr_rrc_dissector.lua #78

Hi,

file Xiaomi.pcap is a .pcap file I've pulled off a Xiaomi 12 phone using --wireshark-live. Unfortunately, the diag_nr_rrc_dissector.lua Wireshark plugin does not decode it correctly: the qcdiag.log.nr_rrc_frequency field seems to be 24 bits long (and not 32 bits, as the plugin assumes). The diag_nr_rrc_dissector.lua file attached produces the correct output.

Best regards Wolfgang

@wolfganghansmann Hi, May I ask how to obtain Xiaomi's baseband logs? Or how to open Qualcomm's baseband logging interface? I cannot obtain logs using adb and modemManager. My phone is Xiaomi k60. Thank you！
