I'm trying to work out a way to use my iPad to connect to as my Raspberry Pi 3 B+ before a network is set up.
There're ways I can think of:
- Use bluetooth network tethering to create a local network - my iPad is Wifi model, so not possible
- Use a portable 4g wireless router - extra device to take, so not favorable
- Exploit External Accessory Framework to make an app to use pi as an external accessory through HDMI to lightening port - viable but may be impossible to do so
Is it possible to make a terminal app that uses an HDMI output source? All HDMI to lightening connectors available seem to output from lightening but not taking input, do I have to make my own connector?
