# FreeDATA
My attempt to create a free and opensource TNC with a GUI for [codec2](https://github.com/drowe67/codec2) to send data over HF channels.
## Under development
This project is still a prototype and not usable at this time.
Build steps for other OS than Ubuntu are provided, but not working, yet.
## Credits
* David Rowe and the FreeDV team for developing the modem and libraries -
FreeDV Codec 2 : https://github.com/drowe67/codec2
* xssfox, her repository helped me a lot in an early stage of development -
xssfox : https://github.com/xssfox/freedv-tnc
* Wolfgang, for lending me his radio so I'm able to do real hf tests
## Running the Ubuntu app bundle
Just download the latest developer release from the releases section, unpack it and just start the ".AppImage file". No more dependencies
## Manual Installation Ubuntu
### 0. add user to dialout group to access serial devices without root
```
sudo adduser $USER dialout
logout / login
```
### 1. Install dependencies, codec2 and FreeDATA
```
sudo apt install git build-essential cmake npm
npm cache clean -f
sudo npm install -g n
sudo n stable
sudo apt install python3 python3-hamlib portaudio19-dev python3-pyaudio python3-pip
pip3 install psutil crcengine ujson pyserial numpy
git clone https://github.com/DJ2LS/FreeDATA.git
cd FreeDATA/gui
npm i
cd ..
cd tnc
git clone https://github.com/drowe67/codec2.git
cd codec2
mkdir build_linux
cd build_linux
cmake ..
make
```
### 2. starting tnc
```
cd /home/$USER/FreeDATA/tnc
python3 daemon.py
```
A successfull start looks like this.
```
running Hamlib from internal library
running Hamlib Version - Hamlib 4.4~git - from precompiled bundle
SRV | STARTING TCP/IP SOCKET FOR CMD ON PORT: 3001
Client connected...
```
### 3. starting gui
There will be an error on startup, that "daemon" can't be found, This is because the gui is looking for precompiled tnc software. This error can be ignored, if you're running the tnc manually from source and should occur if you're using the app bundle.
The gui is creating a directory "FreeDATA" for saving settings in /home/$USER/.config/
```
cd /home/$USER/FreeDATA/gui
npx electron main.js
```
If you're starting the gui, it will have a look for the daemon, which is by default "localhost / 127.0.0.1". The main window will stay blured as long as it can't connect to the daemon.

If you want to connect to a daemon which is running on another host, just select it via the ethernet icon and enter the ip address.
![gui disconnected](https://raw.githubusercontent.com/DJ2LS/FreeDATA/main/documentation/FreeDATA-connect-to-remote-daemon.png "TNC disconnected")
As soon as the gui is able to connect to the daemon, the main window will be getting clear and you can see some settings like your audio devices and connected USB devices like a USB Interface III or the radio itself.
You can also set advanced hamlib settings or test them. Your settings will be saved, as soon as you start the tnc.

If you set your radio settings correctly, you can start the TNC. The settings dialog will be hidden and you can control the TNC now.
