The invention discloses a technique that enables a device lacking master-slave switch capability to establish a connection with a piconet and becoming a slave. The invention is particularly suitable for applications where a role exchange is required, such as when a requesting device attempts to access a Bluetooth LAN access gateway where the gateway needs to maintain master status and the device slave status. In an embodiment of the invention, a first device sends an inquiry (300) to a second device followed and receives identifying information of the second device. The first device pages (310) the second device using the received identifying information to establish a first connection thereby establishing the first device master of an ensuing piconet. The first device terminates (320) the first connection which signals to the second device to initiate a connection with the first device. The second device pages (325) the first device using the identifying information from the previous inquiry (300) to establish a second connection (330) and thereby making the second device the master and the first device a slave in the piconet.
