Issues with Android 11

[thomasjetzinger]

I'm trying to use the WiFi NTRIP Master as a Socket Server to connect the MapIt GIS Spatial application to a simpleRTKBlite board. On Android 10 everything worked as expected, because the hotspot IP address was always the same and I was able to enter a fix IP in the MapIt application. But on Android 11 the last two areas (/16) are changing if we reenable the hotspot. Therefore I'm not able to set a fixed IP anymore and always have to reenter the address, which is very annoying.

1. Is there a way to enable some kind of DNS in order to be able to enter the hostname in the Android app?
2. Is there another way to get this working?

@thomasjetzinger Please edit title to "Hard to use with varying IP address due to Android 11 hotspot random network prefix" or something like that.

I've also run into this, and find that while the third digit changes, the last (host) digit remains the same. So I open up Termux, run ifconfig, and then edit the IP address. Not great, but workable in 30s.

I'm not sure what the fix should be. I think it could be one of:

• bluetooth support - see Add bluetooth support for obtaining NMEA #48 - to avoid WIFi for the SimpleRTK*/phone connection
• add a feature to make outbound connections to the router, rather than a fixed address, so that software which can listen (which includes Vespucci) can work without configuration.
