The Bluetooth specification is a low-cost, low-power radio standard that is used for wirelessly connecting devices. Global acceptance of this specification has helped incorporate limited range wireless communication into everything from automobiles to web players. Based on a nifty time-sharing architecture featuring frequency-hopping and tiny packet sizes, Bluetooth uses the 2.4GHz radio band with a range of approximately 30 feet.
Apple PowerBook G4 portables were the first big time, mainstream computers to offer Bluetooth 2.0+ Enhanced Data Rate (EDR). At that time, other computers were saddled with the older Bluetooth 1.x support. Bluetooth 2.0+EDR, while backwards-compatible with Bluetooth 1.x, is up to three times faster than the older standard. A maximum data rate of up to 3 Mbps is possible with Bluetooth 2.0+EDR. This throughput plus the peripheral nature of the connectivity feature has enabled some vendors to describe Bluetooth as wireless USB.
Lucky for you, the iRobot Create can be equipped with a Bluetooth Adapter Module (BAM) for enabling wireless control from any Bluetooth-equipped host. In fact, with very little technical expertise you can replace the Create USB serial cable with BAM for piping Open Interface (OI) command strings wirelessly to your Create. Take that:
