});
DeviceEventEmitter.addListener("OnReceiveMuseDataPacket", args=> {
	var [type, channelValues] = args;
	console.log(`Type: ${type} ChannelValues: ${JSON.stringify(channelValues)}`);
	// ex: "Type: eeg ChannelValues: [0.0,728.901098901099,998.0586080586081,1517.838827838828,-1000000000,-1000000000]"
