How can I send short messages using Bluetooth?

A. It's actually quite easy to use this wireless medium to send messages to each other, perhaps as a way of communicating during a meeting, with the content unseen by everybody else in the room? (A SMS text message might take a while to be delivered and would cost real money) All the basic functionality you need for Bluetooth communications is built-in, don't worry.

Somewhere on your main applications menu (often in the 'Extras' folder) will be a shortcut to 'Notes'. Use 'New note' and type in the message to your friend or colleague in the normal way. When ready, use 'Options' 'Send' 'via Bluetooth' and pick the recipient's device from the list of Bluetooth equipment in your environment. If the recipient's device is already paired with yours then he or she won't have to explicitly 'Accept' your Bluetooth transmission.

On the recipient's smartphone or PDA, their Messaging/Inbox application will leap in and allow them to view your message, which will have been transferred as a simple text file. Most devices can display text files without needing third party software.
