■ For a Bluetooth v2.1 (or above) phone the device pairing is without a PIN code
Proximity pairing is based on finding and pairing with the closest phone. To do this, the device finds the loudest phone
by carrying out RSSI power threshold measurements. The loudest phone is the one with the largest RSSI power
threshold measurement, and it is defined as the closest device. The device then attempts to pair with and connect to
this device.
Proximity pairing is configurable using the Headset Configuration Tool available from www.csrsupport.com.
16.1.9 Proximity Connection
Proximity connection is an extension to proximity pairing, see Section 16.1.8. It enables the device‑user to take
advantage of the proximity of devices each time the device powers up and not just during a first time pairing event.
Proximity connection enables a user with multiple handsets to easily connect to the closest discoverable phone by
comparing the proximity of devices to the device at power-on to the list of previously paired devices.
