Abstract

According to an aspect, there is provided a first radio device comprising means for performing the following. The first radio device transmits, using a connectionless mode, an advertising message. Subsequently, the first radio device receives, from a second radio device at a second reception time instance measured by the first radio device using the connectionless mode, a scan request. The first radio device transmits, to the second radio device, the scan response using the connectionless mode. Finally, the first radio device performs an auxiliary activity involving wireless communication between the first and second radio devices. The performing of the auxiliary activity is initiated at a first starting time defined to occur at a pre-defined time interval following an anchor point corresponding to the second reception time instance or to a subsequent timestamp generated in response to the receiving of the scan request at the second reception time instance.
