Broadly, this process requires the following steps that are detailed below.

a) Discover the device

b) Secure the relationship (unless you’ve set BL-521 to a low security setting)

c) Connect to the Serial Port Profile

d) Connect your application to the COM port.

5.2.1. Discover the device

This is performed in Brain Boxes 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.

5.2.2. 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.

If you have configured your BL-521 from the menu to use a low security mode (and thus not require bonding)

then this step can be skipped and you can jump straight to section “5.2.3 Connect to the profile”.
