The NAO® BlueListener device is part of Pole Star NAO suite.
The new generation NAO® BLueListener is a single, secure device that can be used simultaneously as a beacon and a listener, meeting all the needs of the NAO suite.
The NAO ® BlueListener collects data from BLE tags in the vicinity, performs measurements on received signals and sends reports to Pole Star NAO Cloud platform over Wi-Fi or Ethernet connectivity.

The NAO BlueListener is a component of the NAO Suite. It is part of the NAO Track solution for real-time BLE tag localization, presence detection and geofencing.
The NAO BlueListener can also be used to densify an existing infrastructure based on BLE-enable wifi access points. As such, it contributes to the concept of a Unified Indoor Location Infrastructure.


The NAO BlueListener device can be easely and securely wall-mounted or ceil-mounted using two screws
As an alternative, double sided adhesive tape (not provided) can be easily stuck on the large flat back-plate.
