Quality of Service in the e-vive™ device is entirely managed by the
Bluetooth Standard Technology and does not require you to configure
any settings to perform device functions.
The coexistence of the e-vive™ wireless system has been tested for up
to forty wireless and microwave devices near the 2.4 GHz band,
including 5 e-vive™ devices operating simultaneously within a 50
meters radius.

The e-vive™ system utilizes encrypted Bluetooth wireless data
transmission to protect information. Additionally, the e-vive™ system
uses Wi-Fi or cellular data connections to transmit usage information
via web service data transmissions that are encrypted and decrypted,
see security note for details.
The QR code of the e-vive™ controller provides a unique controller ID
address (6-character alphanumeric code) that allows only mobile
devices that have been paired to the e-vive™ controller to connect to
and operate the e-vive™ device. To prevent any un-authorized access,
only provide your QR code or controller ID to persons that you may
allow to access or control your e-vive™ device.
Note: Web service data transmissions use TLS 1.2 protocol with AES-
256 cipher encryption.
