1. A first radio device comprising:
at least one processor; and
at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the first radio device to perform:
transmitting, using a connectionless mode of the first radio device, an advertising message;
receiving, from a second radio device at a second reception time instance measured by the first radio device using the connectionless mode, a scan request requesting transmission of a scan response, wherein the second radio device is a device which received the advertising message;
transmitting, to the second radio device, the scan response using the connectionless mode; and
performing an auxiliary activity involving wireless communication between the first and second radio devices, wherein 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.
