Hi Alan,
I’m now realizing that I may have misspoken before. Sorry about that, I must need more coffee today. I just want a local connection between the phone and Pi.
In summary:
- Pi acts as AP
- phone connects to Pi
- Pi sends data locally to the phone
- Phone sends data to cloud using its cellular
The way I’m doing this on Raspbian is by having the Pi effectively black hole any packets it receives. So the phone connects to the Pi using the standard wifi menu in settings. Once connected, it realizes that the AP isn’t connected to the internet and uses its own cellular. I can still access the web on my iPhone, and I can run a simple program on the Pi to send data to the phone. I apologize if I’m being confusing. Let me know if I can clear any of this up.
