Stupid me, thank you MaFu for the clarification. Now I understand how the system would work, but I am still not very happy with the idea. Afaik, the esp would be connected to the rpi trough a serial connection and I have doubts about the transfer speed.
Changing a bit the subject, I've just got to a
post which for somebody's question about internet availability while connected to GoPro wifi states that: 'As a workaround, you should keep cellular data activated on the phone. Then the Wi-Fi will be connected to the camera signal but you'll still be able access the internet via the phone's data plan'. So seems that answer for my question #1 is 'yes'
Now I would need to find out what app should I write on the phone, to answer my question 2.
For a little more clarification, here's how I would see the whole system working:
- user accesses a webpage from anywhere in the world. This webpage is stored on the Android phone, so Android phone should run a webserver.
- the main page displays a list with names of all pics and movies residing on the GoPro
- user clicks one movie or pic name and the image or the movie is displayed in the web page
Also, there should be a way for the user to see in the webpage the current stream the GoPro is filming.
