The FireBat adds AAA battery capability to the FireFly Serial adapter- the world's smallest, lightest and most capable Class 1 Bluetooth serial adapter. Rechargeable AAA Batteries and Power Supply Optional.

FireBat uses the standard Bluetooth Serial Port profile and is compatible with all clients running under Windows™, PalmOS™, PocketPC™ and other Bluetooth enabled platforms.

There are three ways to utilize a FireBat:

1. Direct to a Bluetooth client: the client creates a SPP connection to the unit and uses a virtual COM style interface. Data is sent and received on the client exactly as if a serial cable was connected to a real COM port on the client.

2. Cable replacement: Pair two FireFlies, or BlueportXP's dongles with simple Dip switches.

3. MASTER mode. FireBat is configured to connect out over Bluetooth into a remote client or an access point or Bluetooth server.
