The FirePlug is a Class 1 Bluetooth™ to USB - serial adapter. It attaches to a USB port on your PC, but presents itself as a Serial Port. No Windows Bluetooth drivers or stacks needed!
Unlike standard Bluetooth USB Adapters, this adapter has more than just a Bluetooth radio in the USB housing. It has an intelligent bluetooth serial device, capable of being permanently "Paired" with another bluetooth serial device, such as the BluePort XP (battery powered) or FireFly (RS232 adapter). With the FirePlug's onboard memory, you no longer need to rely on Windows to remember the connection. You can reboot your PC, turn it on and off, upgrade to Vista, you can even move the FirePlug from one PC to another - it doesn't matter. The FirePlug has the power to run the Bluetooth SPP (Serial Port Profile) on its own with no help from Windows, and it stores its bluetooth pairing information in its onboard flash memory. So set it up once and forget it!
With the FirePlug's Class 1 Bluetooth Radio, you can transmit your serial data up to 100 meters (330 feet) away. FirePlug utilizes the latest in USB to serial conversion circuits. Just plug it into your USB port, and Microsoft certified drivers are installed automatically. Windows will create a serial COM Port, and then you can configure and control the FirePlug using simple ASCII strings (AT Commands) over the COM port, no GUI or API drivers into Bluetooth stacks need to be used or written. By using the simple COM interface, a more reliable and stable connection can be made and maintained.
The FirePlug 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.
