In these instructions the operating system is installed and configured for headless operation
Python software FortiusAnt downloaded (with LED support) and installed
Autostart set up
LEDs connected
Hardware Requirements:
- PC
- Software to write the operating system to the SD card. Download from this address https://www.raspberrypi.org/software/
- Rasperry, preferably Raspi4, because it is much faster when compiling. (RP3 also works, Zero ???)
- Fast SD card with at least 16GB. The install process is taking a long time
- Network cable
- ANT + dongle
- TacxTrainer
- Head Unit T1932
- For Rouvy/Swift you need a tablet with an integrated ANT+ or a second ANT+ dongle for the mentioned PC
Installation of the system without use of additional keyboard and screen.
With autostart and status LEDs. With optional connection via VNC. The graphical user interface still freezes. However, this does not matter because the headless operation still works perfectly.
Write the Raspberry PI OS (32-bit) image to SD card (1.1GB) Remove the SD card and insert it again so that the PC reads the SD card partitions again. The boot partition can be read normally by the PC. To get access via SSH for the installation, the trick is a "dummy" file to activate SSH server. Copy an empty file called "ssh" (without any extension) to the SD-card in the PC. You put it to the boot partition of the SD card.
Then put the card into the Raspi. Connect Power supply and network cable to the router.
Open the command window on the PC and enter the following command. ssh pi@raspberrypi
password: raspberry
Since the dummy ssh file is automatically removed from the boot partition, the SSH server must be switched on permanently. Start the raspi-config program and activate the SSH server
sudo raspi-config
3 Interface Options Configure connections to peripherals
P2 SSH Enable/disable remote command line access using SSH
sudo apt-get update
sudo apt-get upgrade -y

Bus 001 Device 006: ID 3561:1932
Bus 001 Device 007: ID 0fcf:1009 Dynastream Innovations, Inc. ANTUSB-m Stick
In this example the first number is the Tacx Trainer, the second is the Antstick. The ID's can differ from model to model. Create the file and adapt the ID's in the file (1932/1009) !!
sudo nano /etc/udev/rules.d/ANT_USB.rules
Copy and paste the following text into nano editor.
SUBSYSTEM=="usb", ATTRS{idVendor}=="0fcf", ATTRS{idProduct}=="1009", RUN+="/sbin/modprobe usbserial vendor=0x0fcf product= 0x1009",MODE="0666", OWNER="pi", GROUP="dialout"
SUBSYSTEM=="usb", ATTRS{idVendor}=="3561", ATTRS{idProduct}=="1932",MODE="0666", OWNER="pi", GROUP="dialout"
Then exit with: Control X Safe modified buffer? y Complete with return
In the previous rules, the USB interfaces were assigned to the “dialout” user group. Therefore the user “pi” must be added to the Dialout group to be able to access this devices.
sudo usermod -aG dialout pi
Download and unzip the special "FortiusAnt" software
wget https://github.com/decodeais/FortiusANT/archive/Raspi-Status-LED.zip -O tmp.zip
unzip tmp.zip
rm tmp.zip
python3 -m pip install --upgrade pip
!!!!!!!! build wheel for wxPython takes hours (Raspi 4 2h, Raspi Zero is rumoret to take 23h). If the Raspi hangs, "reboot" (command: sudo reboot) and repeat the step
Stop the unnecessary X-Server with the command "sudo pkill x". To save resources while compiling.
sudo pkill x
It also helps to increase the size of the swapfile. To do this, the following file must be edited.
sudo nano /etc/dphys-swapfile
CONF_SWAPFILE=1000 von 100auf 1000 ändern.
Call up the new setup to apply the change
sudo dphys-swapfile setup
sudo /etc/init.d/dphys-swapfile stop
sudo /etc/init.d/dphys-swapfile start
Since wxPython has to be recompiled for the Raspberry the required dev packages have to be installed. The FortiusAnt program could not be started with any older version of wxPython
sudo apt-get update
sudo apt-get install dpkg-dev build-essential libjpeg-dev libtiff-dev libsdl1.2-dev libgstreamer-plugins-base0.10-dev libnotify-dev freeglut3 freeglut3-dev libwebkitgtk-dev libghc-gtk3-dev libwxgtk3.0-gtk3-dev -y
sudo apt-get install python3.7-dev`
pip3 install -r ~/FortiusANT-Raspi-Status-LED/pythoncode/requirements.txt
Make the startupscript executable
chmod a+rwx /home/pi/FortiusANT-Raspi-Status-LED/StartUp/FortiusAntHeadless.sh
Create a file with the editor and insert the code:
sudo nano /etc/xdg/autostart/antifier_.desktop

Access to the graphical user interface via RealVNC. Start the raspi-config program and activate the VNC server
sudo raspi-config
3 Interface Options Configure connections to peripherals
P3 VNC Enable/disable graphical remote access using RealVNC
Change monitor setting for VNC without monitor. Otherwise the VNC server will not work if no monitor is connected.
sudo nano /boot/config.txt
Remove the commet marks in the “/boot/config.txt” file for the following options.
framebuffer_width=1280
framebuffer_height=720
hdmi_force_hotplug=1
The Raspi4 can be switched on and off optionally with a button. The button must be switched between GPIO pin 3 and GND. To do this, add this line to the Boot.txt file.
