Reverse-engineering Nespresso Prodigios ble interface and creating flask api on Raspberry pi 4 (4gb).

Contributions are very welcome.

Running the solution:

1. Build docker image
2. Kill bluez on host machine: sudo killall -9 bluetoothd (see source 5)
3. Run docker container: docker run --rm --net=host --privileged -it myimage:mytag

The api currently support /status (current status of nespresso machine e.g. "OK", "Brewing..." or "Slider error") and /brew/<string:brew_type> for brewing coffee.

• Add support for remaining machine alarms and status codes.
• Cleanup and commenting of code :)
• Use Class to handle machine state instead of dict.
