On your computer, install and run the free program OpenTrack.
Press the Windows key -> type "Firewall" -> "Firewall & Network Protection" -> "Advanced
Settings" -> Inbound Rules -> New Rule... -> Program -> Program Path to opentrack.exe
(probably "c:\program files (x86)\opentrack\opentrack.exe")
Right click on your network symbol at the bottom right of Windows, choose "Open Network & Internet
Settings" -> Change Connection Properties -> Choose "Private" instead of "Public" (this will make
your PC discoverable to your mobile device)
Press the Windows key -> "Command Prompt" -> type "ipconfig". Find your local IPv4 address (normally
starts with 192.168... but maybe 10.0... or theoretically something else)
Now restart OpenTrack.
In Input, choose UDP and open up the settings and note the port (probably 4242).
As Output, choose "Freetrack 2.0 Enhanced" and "Both" in its settings.
In Options, bind a hotkey of your choice to "Center" (say, F10)
Press Start in OpenTrack.
On your mobile device:
(If you have more than one wifi around you to connect to, then in your phone, set any other wifis
"Auto-Join" to "off")
Now restart SmoothTrack.
As "IP address" in SmoothTrack, enter the local IPv4 address from above.
As "Port", enter the port from above.
If the octopus is moving, you are good to go!! Launch your game that supports TrackIR and it should work.
Email support is provided if there are any issues.
Here is an example OpenTrack config that I find works pretty well for me with FS2020: Put this file into
your Documents/opentrack-2.3 folder: default.ini
