Abstract
According to an aspect, there is provided a first radio device for performing the following. The first radio device causes wireless transmission of one or more first advertising messages at one or more advertising radio frequencies using a connectionless mode of the first radio device. The radio device receives, for at least one first advertising message, a first scan request from a second radio device and transmits, for each first scan request, a first scan response to the second radio device. Based on one or more received first scan requests, the first radio device performs bi-directional channel sounding with the second radio device at one or more sounding radio frequencies. The first radio device receives, from the second radio device, at least one first message comprising information on second channel sounding measurements and transmits, to the second radio device, at least one second message comprising information on first channel sounding measurements performed by the first radio device.
