    Default Qualcomm Signaling decode alternative

    As some of the biggest public sharing platform was reported by some dickhead,it becomes very hard to get Qualcomm support tools nowadays,like QXDM/QCAT,for signaling decoding ,there is an alternative open-source method that can well handle LTE message so far,possible NR in the future.
    Stop wasting time in finding usable QXDM/QCAT toolsets

    For Windows, you have to install libusbK driver for diag port.
    Code:
    1- Download and install “Python 3.8” from Microsoft Store https://www.microsoft.com/fr-fr/p/py...ot:overviewtab
    2- Download and unzip “scat-master.zip” in “C:\” from https://github.com/fgsect/scat
    3- Download “pyusb 1.0.2.tar.gz” from https://pypi.org/project/pyusb/ , copy in “C:\scat-master” and rename it “pyusb.tar.gz”
    4- Download “pyserial 3.4.tar.gz” from https://pypi.org/project/pyserial/ , copy in “C:\scat-master” and rename it “pyserial.tar.gz”
    5- Copy your “qmdl log” from your phone in “C:\scat-master” and rename it “1.qmdl”
    6- Press Windows+R to open “Run” box. Type “cmd” and then click “OK” to open Command Prompt.
    7- run ”cd c:\scat-master”
    8- run “pip install pyusb”
    9- run “pip install pyserial”
    10 -run “python scat.py -t qc -d 1.qmdl -F 1.pcap”
    Now you can use Wireshark and find UE Capability Information message .
    
    Execute “Wireshark.exe” and open file “1.pcap” in “c:\scat-master”

    this is the static capture way,you can check the dynamic diag port with libusbK driver

    Thanks, but I can't find qmdl file. The only availablr is qmdl2, I think this is new format. Do you have any idea for qmdl2 file?

    I didn’t check it, I just found it in Google
    Scat
    This is program to convert qmdl, qmdl2 and dlf file to pcap file. This program requires python to be installed to your local computer.
