I got a RPI4 and I would like to use it outside, where there is not always an avaiable Wi-Fi connection . I would like to create a sort of an headless machine and control it with a smartphone, without having to reconfigure it everytime I use it.
1) What are the ways I could use to control it "wirelessely" ?
2) Should I try to turn it in a hotspot and connect to it via Wi-Fi with the smartphone ?
3) Or should I try to make it connect to the hotspot of the smartphone ?
4) Can I use Wi-Fi direct with a RPI4 ?
