InfoCom Drone Project - Part 2 - Microservices

Install the required Python packages if not done already (you probably did this in the previous assignment):

sudo apt update
sudo apt install python3-socketio
sudo apt install python3-engineio
sudo apt install python3-flask-socketio
sudo apt install python3-flask-cors

Go to /webserver, start your Redis server (if it is not already running, which it probably is – test using redis-cli) and run the two flask servers:

1. Run server for writing data to the redis server

export FLASK_APP=database.py
export FLASK_DEBUG=1
flask run --port=5001

2. Open a new terminal, go to /webserver and run build.py

export FLASK_APP=build.py
export FLASK_DEBUG=1
flask run

Open a web browser (e.g. Chromium) on your Raspberry Pi and enter the following URL. You should see a map of Lund as in the previous assignment. Make sure you see a red dot representing the drone at the LTH location.

http://localhost:5000

Open a new terminal, go to /pi and run the Pi controller:

python3 pi_controller.py

You can replace pi_controller.py with the one you created in Part 1, but keep SERVER_URL the same as in the file provided in this lab. Make sure you can move the drone on the map using pi_controller.py.

Note: Don't use python3 build.py or python3 database.py to run the webservers, since this does not provide all the functionality required by the application.
