Using blueM
Once the blueM software is installed on your Palm, you are ready to begin
making connections to other Bluetooth equipped devices.
There are two main stages in getting Bluetooth devices to work together:
• Firstly, one device must discover the other, and
• Secondly, the devices then swap security passkeys in order to become
paired.
Once paired, the two devices can request and supply information or services as
required. For each set of devices, the pairing process need only be carried out once
and from that moment they can call directly to each other as necessary (providing
they are within range, i.e. within ten metres).
The discovery and pairing characteristics of your Palm (and blueM) are controlled
from the standard Palm Preferences application.
The reason for discovery and pairing
From its initial conception, the Bluetooth standard has been designed with security in
mind. Obviously, when your Palm can theoretically be accessed by any other Blue-
tooth device, you need to be sure that you are in control of how, and by whom it is
being accessed. For this reason, the process of getting most Bluetooth devices to
work together is divided into two distinct stages - Discovery and Pairing.
To understand the process, imagine a group of people in a dark room. Person A
wants to find someone to talk to among all the others. So person A calls out if
anyone is there (discover). Person B does not want to be discovered so they don’t
reply (non-discoverable). However, person C does want to be known (discoverable)
and shouts out their name, possibly along with many others. Person A then chooses
person C from a number of responses and asks them directly for more details.
Person C then asks for a secret password (passkey) before the conversation gets
any deeper. Providing the right number or word is given, they form an instant
trusting relationship (pairing) and from that moment on, whenever they need to
share information, they simply call each other by name.
Controlling Bluetooth with Preferences
On your Palm, the central point for controlling basic Bluetooth operation is within
the Palm Preferences application. During the software installation a new
Bluetooth page was added to Preferences and from this new page, you can:
• Begin a search to discover new devices,
• Set your Palm to be discovered,
•View or delete existing paired devices, and
• Alter various settings.
To display the Bluetooth Preferences page:
1 Tap to locate the icon.
2 Tap the icon.
3 If the Bluetooth Devices screen
is not already showing, tap the
in the top right corner and
select Bluetooth from the drop
down
list !
4 Using this screen you can now
control the basic Bluetooth
capabilities of your Palm and
blueM combination as covered
