Configuration

Requirements

• Emotiv Headgear (Plugin tested with INSIGHT)
• Emoiv App (Emotiv Installer)
• Java 15.X (Plugin tested with Java 15.0.1, Download Page)
• Apache Maven 3.X (Plugin tested with Apache Maven 3.6.3, Download Page)
• Spigot Server (Tutorial)

Download the latest stable release to your plugins directory of your server. Rename this file to CortexPlugin.jar. Add another directory plugins/CortexPlugin and create a file plugins/CortexPlugin/credentials.json containing the following (retrieved from your cortex account):

{
	"clientId": "your client ID here",
	"clientSecret": "your client secret here",
}

Your server directory should look like the following

.
├── plugins
│   ├── CortexPlugin
│   │   └── credentials.json
│   ├── CortexPlugin.jar
│   └── ...
└── ...

Run the server. You may have to accept the connection request from the Emotiv App on the first attempt. If a connection error occurs, try restarting the server.
