Setting up Raspberry Pi for EduROV with a fresh image

-Install the official Raspberry Pi Imager tool

• Insert your SD card into a card reader
• Use the tool to install Raspberry PI OS (32-bit) onto the card
• Don't forget to configure the image to use SSH before writing it
• Insert sd card to Raspberry Pi
• Connect via ssh to raspberrypi.local
• Via raspi-config:
  • Under Interface Options
    • Enable camera
    • Enable Serial Port:
      • We do not want a login shell to be available.
      • We do want the serial port hardware to obe enabled.

• Install pyedurov3 with sudo pip install pyedurov3
• Call sudo pyedurov3 --runatstartup --name=yourname to set server to start at boot with "yourname" as the advertising name.

Building package (and tips for developers)

For development, you will have to build modified versions of the package from source. Make sure the newest version of pip is installed: pip install --upgrade build Then navigate into the upper pyedurov3 folder and run python -m build (you might have to use sudo for that).

In development it can be helpful to quickly reinstall the package without debendencies. A helpful command is this: python3 -m pip install --upgrade --force-reinstall --no-deps dist/pyedurov3-0.0.0.tar.gz. The source code can alos be run from the run.py file so you don't have to rebuild the package every time you change something. Just navigate into the upper pyedurov3 folder and type python3 -m run.py
