Universal USB Receiver (Dongle)
The universal USB receiver (dongle) uses a proprietary 2.4 GHz protocol to stream data
from the headset. We recommend using this to connect to your headset on a PC or Laptop;
once connected it remembers the serial number of the headset pairs to allow easy
reconnection. The dongle pairing also allows multiple headsets to co-exist and provides a
reliable high speed connection over Bluetooth Low Energy (BLE).
The headset supports BLE which allows connection to mobile devices (Android/iOS) and
some computers. EmotivPRO does support the native BLE radio on MacOS devices (2015
or later). On PC's however the implementation of Bluetooth varies by manufacturer and it is
not guaranteed to work and so we recommend using the dongle.
There are two green LED's on the top surface of the dongle and plastic lies at the bottom.
The following table explains about LED's.
