General information about Callibri
The Callibri sensor connects to an external device
(desktop computer, tablet or mobile phone) with
the help of Bluetooth Low Energy (BLE) wireless
technology. The quality and stability of this connection
depends in large part upon the operating environment
and proper procedure by the user.
To ensure a stable connection between Callibri and
the external device, follow these recommendations:
• Do not cover Callibri or the external device with
your body or other objects; preserve direct line of
sight between devices. This requirement is due
to the fact that Bluetooth Low Energy uses a 2.4
HZ radio frequency. At this frequency, radio waves
have difculty passing through obstacles.
• For use with desktop computers, use a high
quality BLE adapter (recommended model Asus
USB-BT400, product not included). It is also
recommended to bring the BLE adapter into close
proximity with Callibri using a USB extension cable
(product not included).
• While Callibri is in use, disconnect all other
Bluetooth devices – especially multimedia
(headsets, etc.) devices – to avoid reducing the
bandwidth available to Callibri. The fewer devices
connected via Bluetooth, the greater Callibri’s
