# codec2 | 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. 
The TNC itself will be completely controllable via network.

## Under development
The project is still a prototype and not usable at this time.
Build steps for other OS than Ubuntu are provided, but the bundle is only running on Ubuntu

## Manual Installation Ubuntu
### 1. Install dependencies and codec2-FreeDATA
A folder "codec2-FreeDATA" will be created in /home/[user]
codec2-FreeDATA needs codec2 to be installed within codec2-FreeDATA/tnc folder.
```
sudo apt install git build-essential cmake
sudo apt install npm
sudo apt install python3
pip3 install psutil
pip3 install crcengine
pip3 install ujson
pip3 install pyserial
pip3 install numpy

wget https://raw.githubusercontent.com/DJ2LS/codec2-FreeDATA/main/tools/install-codec2-FreeDATA.sh
chmod +x install-codec2-FreeDATA.sh
./install-codec2-FreeDATA.sh
```

### 2. starting tnc
You need to set the "--debug" option. Otherwise daemon.py is looking for precompiled binaries which causes an error
```
cd /home/[user]/codec2-FreeDATA/tnc
python3 daemon.py --debug
```

### 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

The gui is creating a directory "codec2-FreeDATA" for saving settings in /home/[user]/.config/
```
cd /home/[user]/codec2-FreeDATA/gui
npx electron main.js
```
