Abstract
Method, apparatus, and computer program product enable devices to advertise an existing connection to other devices so that they can synchronize to the connection and listen to the information exchanged, in a listen-only mode. In example embodiments, after a slave device has joined a piconet by completing a connection with a master device using for example the Bluetooth Low Energy protocol, the slave device possesses all of the information needed to advertise the existing connection to other devices so that they can synchronize to the connection and listen to the information exchanged, in a listen-only mode. The slave device may assume the role of an advertiser of the existing connection and may begin transmitting an advertising channel packet/PDU to inform third party devices about the existing connection. When a third party device receives such an advertising channel packet, it may adopt the connection parameters from the packet and synchronize to the existing connection to start receiving packets in the connection, in a receive-only mode.
