Bluetooth TM 2.0 (EDR) Serial Adapter
Roving Networks, a leading developer of wireless intelligent network appliances,
introduces the FireFly Bluetooth serial adapter. This device gives any RS232 or 422 serial
port Bluetooth capabilities.
True Plug-and-play
Smaller than a business card, FireFly easily attaches
to RS232 or 422 serial ports via DB9 male or female
connector. Often no software configuration is needed,
just plug it on and start connecting!
Tri-mode Operation
Three connection modes are available:
• Slave Mode- Bluetooth clients, such as Palm/Pocket PC PDA’s, laptops, scanners, cellphones directly
connect to FireFly via Bluetooth Serial Port Profile, creating a Virtual COM port on the client.
•Instant Cable -matched pair of FireFlys link to each other for a wireless cable replacement.
•Master Modes- FireFly can automatically (or manually via software control codes) discover and
connect to other Bluetooth SPP devices in master mode. FireFly can also trigger on incoming data and
auto disconnect when data transfer is complete to minimize power.
