Having recently found a way to get the apps to communicate with each other has been a great milestone. It has allowed the below updates to be possible.
Now communicates with Nuzzi Race Engineer App (v2.4 or higher.) This will allow the Race Engineer to know when DRS has been enabled/disabled.
Now communicates with Nuzzi Rolling Start App (v3.2 or higher.) This allows this app to automatically know when a rolling start is set so the DRS can be enabled one lap later.
Now communicates with Nuzzi Race Engineer App (v2.4 or higher.) Now the Race Engineer automatically knows when using standing or rolling starts.
Now communicates with Nuzzi FIA DRS App (v2.2 or higher.) Now DRS is automatically one lap later when using rolling starts.
Now communicates with Nuzzi FIA DRS App (v2.1 or higher.) Race Engineer now reacts to FIA Enabling/Disabling DRS.
Now communicates with Nuzzi Rolling Start App (v3.3 or higher.) Race Engineer now automatically knows when rolling/standing starts are being used. There are some new voice lines for rolling starts too.
Thanks again everyone for your support. :)
