1 Choosing a Communication Target We begin by showing how to choose a communication target. py from bluetooth import * target name = "My Phone" ¯ target address = None ¯ nearby devices = discover devices ( ) ¯ ¯ for address in nearby devices : ¯ if target name == lookup name ( address ) : ¯ ¯ target address = address ¯ break if target address is not None : ¯ print "found target bluetooth device with address" , target address ¯ else : print "could not find target bluetooth device nearby" A Bluetooth device is uniquely identified by its address, so choosing a communication target amounts to picking a Bluetooth address.

A server application waiting for an incoming Bluetooth connection is conceptually the same as a server application waiting for an incoming Internet connection, and a client application attempting to establish an outbound connection behaves the same whether it is using RFCOMM, L2CAP, TCP, or UDP. For this reason, extending the socket programming framework to encompass Bluetooth is a natural approach. This section gives a brief introduction to the essential concepts behind socket programming without any distracting code.

The later half of the chapter can be considered more advanced. Several topics are addressed, including asynchronous and audio communications. 1 Choosing a Communication Target We begin by showing how to choose a communication target. py from bluetooth import * target name = "My Phone" ¯ target address = None ¯ nearby devices = discover devices ( ) ¯ ¯ for address in nearby devices : ¯ if target name == lookup name ( address ) : ¯ ¯ target address = address ¯ break if target address is not None : ¯ print "found target bluetooth device with address" , target address ¯ else : print "could not find target bluetooth device nearby" A Bluetooth device is uniquely identified by its address, so choosing a communication target amounts to picking a Bluetooth address.
