Abstract
A system and method for switching master and slave roles of devices for use in wireless communications. The method includes: establishing a monitoring link for communications between a master device and a host device; and initiating a role exchange request, in which a time point for role exchange is appointed, by the master device or a slave device via the monitoring link when role switching between the master device and the slave device is triggered, and replying with a request receipt acknowledgment packet for the receipt of the role exchange request by the other device via the monitoring link. The system includes the master device, the slave device, and the host device, wherein the master device includes a master processing module; and the slave device includes a slave processing module. The role exchange between the master device and the slave device keeps energy consumptions of the two devices evened out.
