Xiegu G90 App for "путін хуй" Xiegu GSOC mod.

g90puhuApp - Tools, examples and CAT for Xiegu G90 and Xiegu GSOC

tools/catsniff.py

This tool was used to sniff CAT communication between Flrig and G90. Created just to get familiar with CIV commands.

Prerequisites

• Linux
• socat
• Python3
• Flrig
• G90 + CAT cable
• Permission to create /dev devices and read/write access to serial devices

    C<-->D["catsniff.py"]
    D<-->E["/dev/ttyUSB0"]
    E<-->F["G90"]

Setup

• Prepare virtual serial devices:

$ socat -dd pty,link=/dev/ttyG90OUT,raw,user=root,group=dialout,echo=0 pty,link=/dev/ttyG90IN

• Start the sniffer

$ python3 catsniff.py

• Start Flrig, setup and init.

Rig: Xiegu-G90
Serial: /dev/ttyG90OUT
Setup: 19200 1

tools/g90sniff.py

This app is a main tool used to sniff communication between GSOC application and G90 main unit. It is based on research found here.

Note: xiegug90head.py header is taken from this repository.

Prerequisites

• GSOC device with custom Linux
• socat
• Python3
• G90 main unit
• Remote access via SSH (for output)

graph LR;
    A[GSOC]<-->B["/dev/ttyVGSOC(*ttyS1)"]
    B<-- socat -->C["/dev/ttyGSOC"]
    C<-->D["G90sniff.py"]
    D<-->E["/dev/ttyG90"]
    E<-->F["G90"]

Setup

Due to closed source nature of GSOC application the setup requires some tricks to make it work as expected. During the research it turns out that GSOC uses /dev/ttyS1 for communication with G90 main unit using head<>body protocol. As for now there is no known method to pass other port as a parameter for a command line. GSOC application is also very picky as it won't accept a link as a device type. It's recommended to start g90sniffer.py using SSH connection as the output requires big console terminal.

GSOC application has also possibility to accept CIV commands on /dev/rfcomm0 port. The same picky nature was observerd here. In order to trick application to listen to command it's required to create non-link entity. In this repository, this method won't be researched as its main goal is to provide CAT sever without GSOC application.

• Rename /dev/ttyS1 to /dev/ttyG90

# mv /dev/ttyS1 /dev/ttyG90

• Create virtual serial ports

# socat -dd pty,link=/dev/ttyVGSOC,raw,user=root,group=dialout,echo=0 pty,link=/dev/ttyGSOC

• Mount /dev/ttyVGSOC as /dev/ttyS1

# mount -o bind /dev/ttyVGSOC /dev/ttyS1

• Start g90sniffer.py (over SSH)

# python g90sniffer.py

• Start GSOC application

# /usr/local/gsoc/gsoc_app_v1

Output

Click on the image below to view sniffer in action:

app/g90app.py

This is just example application that may control G90 main unit. The only supported features are:

• volume - +/-
• PTT - toggle with Space
• modulation - ]/[

Prerequisites are the same as for g90sniffer.py

Usage:

# python g90app.py

header/xiegug90head.py

This header file is required by g90sniffer.py and g90app.py. Just put it in the same folder as python application. All creditis for this one go to developers from this repo
