Qualcomm Signaling decode alternative

[freeinfo123]

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.

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”

Power enough for 3GPP standard OTA signaling analysis

Appreciate your efforts but mind your language.Can you explain step 5 a bit more.

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.

It says working well with qmdl2,but I got CRC error when test

It claims to coperate with qmdl2,but actual not

I can obtain OTP to put Most Samsung Galaxy Device into Engineering mode, and setup it to capture HDM, QMDL, QMDL2 files. But this python is no longer able to convert UE BIN to PCAP. I am getting CRC error. On the older Galaxy 7, I can actually see the SIBs and MIBs messages.

If any one need to put Samsung Galaxy *.* into engineering mode, pm me.

I need to find other method do read these Binary Samsung UE Logs (I think that chipset may decides the format of the files.

thanks
