3.2.1. Discover the device
This is performed in Brainboxes Windows software by first opening the “My Bluetooth Devices” window and
clicking the discovery button. This sets the software to display all the Bluetooth devices it can find “in range”.
Assuming that your BL-521 is switched on and in range you should see it displayed (perhaps alongside other
Bluetooth devices in range) in the main screen.
3.2.2. Secure the relationship
This is where you must “Bond” or “Pair” with the device. This is a feature of Bluetooth, which allows secure
communications to take place. It is also used to stop other devices from performing unauthorised connections.
You can start the bonding process by selecting and right clicking on your BL-521 from the main screen. This
brings up a context menu from which you should select the “Bond” option.
