Abstract
A BLE system includes a network controller, peripherals, and centrals. As one of the peripherals begins to roam, the current central in a connection with the peripheral detects when the peripheral device is moving away from the current central and reports the roaming to the network controller. The peripheral receives a request from the current central to advertise for handoff evaluation during the connection and the other centrals receive requests from the network controller or from one or more of the centrals to scan for handoff evaluation purposes. The centrals determine the received signal strength from the received advertising packets and send the received signal strengths to the network controller. The network controller determines a next target central based on the received signal strengths. The network controller then causes the peripheral to disconnect from the current central and the current central advertises and establishes a connection with the next target central.
