Go to the setting page, then type in the IP address and the port number of the computer for FlightGear. In this case, we can use 23333 as the port number. Click Save.

Type in --generic=socket,in,20,,23333,tcp,from_fgyoke in settings when launching FlightGear.

Start FlightGear, and click on the switch icon in the app. If it stays on "On" position, the connection was successful.

Tips to reduce latency in iOS version

There may be some latency due to a bad Internet environment. If you have a lightning cable, you may make use of the Personal Hotspot.

After connecting your iPhone/iPad to your computer, switch on the personal hotspot of your phone and check the Internet settings of your computer to make sure it is connected (In MacOS, there should be an iPhone USB tab in settings). Then either check your IP address in settings or using ifconfig/ipconfig depending on what system you are on.

This method could also be used when there is no Internet available for FGYoke.

Haven't been tested, but the Android version should also work in the same way.
