10.2 Connection Quality
The SMA Bluetooth Repeater can only display the connection quality if it is integrated into an existing
SMA Bluetooth network. The Bluetooth network is only established by master devices
*
. A device
always shows the connection quality to the device that established the connection to it.
* Master is a network engineering term. In a network, a master is a device that requests other devices (slaves)
to receive or send data, for example. All communication products (e.g. Sunny Explorer, Sunny Beam with Bluetooth) are masters
in an SMA Bluetooth network.
