Run the Python script on startup using crontab. Make sure you run it from within a virtual environment. Check the old Raspberry Pi (run crontab -e).

I followed this guide and ran this command sudo crontab -e and added this line @reboot python3 /home/bzzz/Desktop/bzzz/raspberry/read_sbus/read_sbus_from_GPIO_receiver.py at the end of the file.

@gunturiCM just be careful with sudo. You may or may not need to use it. Does it work now?

Had some issues. But everything is fixed now. The Python script in a virtual environment starts after powering up as expected.

This is for future reference

The modifications were: In crontab, the above line was changed to @reboot sleep 10 && /home/bzzz/Desktop/run_sbus_rx.sh and the shell script from the previous setup was modified and added to the desktop. The contents of the bash script are.

#!/bin/bash

pushd /home/bzzz/Desktop/
source bin/activate
python3 /home/bzzz/Desktop/bzzz/raspberry/read_sbus/read_sbus_from_GPIO_receiver.py
popd

Then python virtual environment support was installed sudo apt-get install python3-venv

Then create and activate the venv.

sudo python3 -m venv /home/bzzz/Desktop/
source bin/activate

Change permissions to allow pip to be able to install modules in venv sudo chmod -R a+rwx ~/Desktop/

Install the required modules inside the venv

python3 -m pip install bitarray
python3 -m pip install pigpio
python3 -m pip install pyserial

Yes, professor, it works now.
