Hi everyone, im working on a color analysis project where my Raspberry Pi captures images and analyzes color changes. I built a Flask web interface to control the system (start analysis, see results, etc.).
Right now, everything works fine only when my Raspberry Pi and my PC are on the same Wi-Fi network. I access it via the Pis IP running the Flask application as a development server.
However, i want to make the Raspberry Pi behave more like a "gadget".
Ideally id like it to:
- Run the Flask app automatically on boot (For this i can running it as a service via systemd).
- Connect to it directly from my phone or laptop via USB, Bluetooth, Wi-Fi etc.
- Let me open the web interface.
- Work without needing internet or my home router.
Im new to networks, linux, raspberrys and all things in relation with the project, haha. I tried searching on internet and have found about "gadget mode" and about making the Raspberry itself an "access point" (this is like making it the router, right?).
So my question is: What’s the best way to turn a Raspberry Pi + Flask web app into a device.
Any guidance, examples, or recommended setups would be really appreciated! I guess that it exists multiple ways to do this, but as i said im kind of lost.
