Raspberry Pi WiFi management using FastAPI

Description

An open source system for managing WiFi file wpa_supplicant.conf on the Raspberry Pi.

WARNING: This repo is for education and does not comprehend security practices around a file you really need to protect. Haven't gotten there yet. Feel free to contribute.

You've been warned.

Why do this?

There were two goals:

Learn more about FastAPI
Hating to modify the wpa_supplicant.conf file by hand
Get better at detecting "off by one" errors

Setup and prerequisites

Current Raspberry Pi as of this writing is Bullseye.

python3 -m venv venv3
. ./venv3/bin/activate
pip install -U pip
pip install wheel
pip install -r requirements.txt

Usage

There is a run-wpa.sh shell script containing the run command for uvicorn

uvicorn wpa_supplicant_api:app --reload --host 0.0.0.0 --port 8089

N.B. 0.0.0.0 opens the API to all outside of the host.

There is a command line version of the program. To get help for it

python wpa_update_cli.py

Settings

The file config.py contains the class Settings for

File path location for wpa_supplicant.conf
Environment variable prefix
The .env file if it exists

N.B. the file /etc/wpa_supplicant/wpa_supplicant.conf is root access only. Take this into account.

Future

The Raspberry Pi OS may switch to a different WiFi management methodology at any time.
