The question may seem highly specific, but I didn't seem any answer anywhere.
Accessing the internet via a bluetooth access point sounds like an odd choice, but I believe it's the right one in my case, where a very small machine with a small battery running debian, should be able to connect to the internet every time once in a while at a low battery cost.
I have, at my disposal, android and ios devices that are able to share an internet connection via bluetooth.
My own device has a micro controller that also has a bluetooth chip. It can normally scan devices, pair to them, and connect to them via bluetooth (done using bluetoothctl), but I couldn't find how to establish an internet connection via a BT device I am connected to.
In fact I don't even know how to test it: can I just leave the bluetoothctl prompt and ping google? Is that even a thing that can be done, provided an internet connection was established?
Thanks in advance.
