The Firefly is a Bluetooth to RS232 serial adapter. It attaches to a RS232 serial port making it a Bluetooth Class 1 wireless connection, capable of transmitting your serial data up to 100 meters (330 feet) away. You can use the Bluetooth Firefly with another Firefly in "cable replacement mode" to make your RS232 cable wireless, or you can pair it with a BluePort XP (battery powered), FirePlug(USB serial adapter) or BluePlug (USB adapter). The Firefly Bluetooth serial adapter may also be paired with any other Bluetooth device that supports Bluetooth SPP (Serial Port Profile). Note that many devices with built-in Bluetooth (e.g. PC's, Laptops, Handhelds and phones) utilize Bluetooth Class 2 radios, which only has a range up to 10 meters, so if you use a Firefly with a Class 2 device, you will only get the effective range of the Class 2 device and not the Firefly.

The Firefly supports the latest and greatest Bluetooth specification 2.0 (which provides faster Enhanced Data Rate (EDR) and lower Bit Error Rate (BER)), but is also compatible with devices supporting the older 1.x specifications.

The Firefly has dip switches to make set-up of the most common serial baud rates quick and easy. It also supports "AT" commands which allow you to change the firefly settings with messages sent through the serial port.
