Bluechat is chat between two or more users, where every one utilizes a bluetooth device (i.e. a modern mobile phone or a PDA) and names it (it will be the user's nickname).

The device is generally used in a public and populated space (like a pub, a street, plaza and so on).

To initiate chat a user goes to the connectivity menu on their device and turns on the bluetooth port. Next, they should discover new bluetooth devices (to add your bluetooth co-chatters).

To send the messages, the user goes to the organizer program, creates a new note and sends it via bluetooth to the other device/user.

In any case, the device can be visibly hidden and vibrating alert feature used.

It is common for users to put presentation items (age or age range, sex, sexual orientation, language, and so on) in their nick names or, if too long, in a general profile note. Users can also send contact items, for example email addresses.

In some premises, the admin can create a bluechat-LAN (i.e. in a hotel, hospital and so on), for a wider bluechat network.

Palm OS based devices have a Bluechat application. For Pocket PC OS and Windows Mobile some freeware are available, including ProximityMail (www.proximitymail.com)
