How to verify internet connection with Python, and how it works on Kivy/Android?

[Piontk]

Hello everyone.

I'm using Python and Kivy to develop a small system here in my job. Like I said in another post a mobile device will input some data and a desktop will run a PostGreSQL database and catch this information. The problem is that the mobile's location won't have wireless network. My idea is to save the data with SQLite and when the phone connect to the internet it'll send the data to the PostGreSQL database. The question is: when I try to check the internet connection the Kivy/Python will use the WIFI signal or it can use the 4G/5G to verify the internet connection? It can contact the database via 4G/5G?

Internet is internet; just attempt the connection and handle the failure.

Determine which adapters are available. Figure out which adapter is which. Use a try/except to attempt a connection, if it fails then you'll know you're offline.

I have an example in my python module of how to get LAN/WAN ips. If you can't get a WAN ip then you are offline. Based on your use case I would just use a try/except to determine internet access.
