Bluetooth
The Bluetooth interface uses the same ID as the default Wi-Fi AP SSID.
For security purposes there is a 10 minute window from initialisation where the Bluetooth interface is available for pairing. After this window expires it will disappear from device lists. Active connections will not be affected by this. If you wish to make the Bluetooth interface visible again for a further 10 minutes you will need to completely remove and reapply the power (including USB). The Bluetooth interface supports data streaming to seven devices simultaneously.
There is also an option to completely turn off Bluetooth if required.
The Bluetooth interface is not supported by Apple devices.
