BLUETOOTH

By default, the Bluetooth module acts as a slave and the PC or smartphone is the master. You connect to the Bluetooth
module using the Bluetooth device manager, which varies depending on your smartphone or computer's operating system.
In all cases, the process is the same:
• Discovery: In the discovery phase, the Bluetooth module broadcasts its name, profile support, and MAC address. It is
ready for other devices to pair with it. Discovery is only availoable in slave mode.
• Pairing: During pairing, the Bluetooth module and the Bluetooth master validate the pin code. If the pin code validates
successfully, they exchange security keys and a channel hopping pseudo-random sequence. Successful pairing results in
the module and master establishing link keys.
• Connecting: Before connecting, the Bluetooth devices must have paired successfully. The master initiates a connection,
the master and slave validate the link keys, and a Bluetooth link is established.

7.4.4.1 DISCOVERY

When you turn on the Bluetooth module, it is discoverable. Open your PC's Bluetooth device manager and choose to add a
new device. The Bluetooth device manager's icon is located in the bottom right corner of your screen in the taskbar for
Windows operating system. The Bluetooth device manager displays a list of discoverable Bluetooth devices (see Figure 1-
3). Instrument "UvilineXXX YYYYYYYYY" should be visible where XXX is the type of Uviline instrument and YYYYYYYY is
the instrument serial number.

7.4.4.2 PAIRING

To pair with the module, double-click the module's name (i.e., Uviline940 150620001) in the list. The firmware automatically
stores up to 8 pairings from remote hosts in a first in, first out fashion. Choose to enter the module's pairing code (see
Figure 1-4) and enter the default pin code, 1234. When the Bluetooth device manager completes pairing, it issues a
message that the Bluetooth device is installed on COMX where COMX is unique to your computer. In some cases, the
Bluetooth device manager creates two COM ports; in this situation, only use the COM port labeled "outgoing."
