CONNECTING WITH HOST DEVICE
There are four ways to connect Nordic ID EXA with host device, being the third one (Nordic ID Smart
Pair) the most advanced and easiest way to connect wirelessly.
1.
Connect without pairing via Bluetooth
Nordic ID EXA21 will advertise itself via Bluetooth allowing the host device to connect. Bluetooth
connection remains active until the host device closes the connection. Once the connection is
closed Nordic ID EXA21 will start advertising again and allowing any host device to connect.
Most applications will not require pairing with the host device. Without pairing, Nordic ID EXA21
can be connected to any host device which can see its advertisement. When Nordic ID EXA21
disconnects from host device, other host devices are available to connect as long advertisement
is seeing from the Nordic ID EXA21.
2.
Connect with secure pairing via Bluetooth
Pairing Nordic ID EXA21 with a specific host device increases security by preventing other hosts
to connect to the paired Nordic ID EXA21. When paired, applications (like Nordic ID RFID Demo)
connect to the device automatically. The connection remains active as long the host device is in
Bluetooth range. Entering a passcode in the host device is needed to allow pairing. The passcode
can be changed and reset to factory defaults by using Nordic ID RFID Demo application (see
section 0).
3.
Connect with Nordic ID Smart Pair feature
The new awesome Nordic ID Smart Pair feature provides an exceptionally easy way to connect
and disconnect host device to our EXA readers. Just select
“
Nordic ID Smart Pair
”
from
“
Connection
”
listing in Nordic ID RFID Demo and host device starts looking for the EXA readers.
Smart Pair works only when EXA is not paired.
4.
Connect via USB
The Nordic ID EXA21 can connected with the host using USB-C type data cable. When connected,
Bluetooth advertising stop and blue led is continuously on. Advertising start again when USB
cable removed.
