There are 3 options for EEG Dev Kit data output:
Stream mode (MQTT)
In “stream” mode device publishes data to server (broker) using MQTT protocol in real time.
MQTT is an Internet of Things (IoT) protocol, provides a lightweight method of carrying out messaging using a publish/subscribe model. EEG Dev Kit is a MQTT client, connects to a MQTT broker and publishes data at specific topic. The broker then pushes the information out to those clients that have previously subscribed to the client's topic. So, any computer that runs a MQTT library can receive data from EEG Dev Kit in real time.
Please, refer to chapter 3.9 "Using Your Own Server" if you want to use your own MQTT broker.
