Understanding the data transfer

When your subjects spend nights with your headbands, records are stored in the headband. To make sure that data is transferred to the Viewer (or Quality Check Portal), make sure of the following:

  1. The headband is plugged to a socket wall
  2. Wifi has been setup in the setting section AND headband is plugged near the wifi router

Depending on your Wi-Fi connection, data transfer time can vary from 10 minutes to a few hours. 

Here is an overview of how data is generated on the server:

What you want: your records to appear in blue-gray or in dark-grey. This means that H5 files and EDF files are available for you to download.
