https://devzone.nordicsemi.com/f/nordic-q-a/123670/about-timeslotHi, I&#39;m currently trying to use the Timeslot feature in the nRF SDK 5 and have a few questions: Can Timeslot be used during the advertising phase? Specifically, during the BLE advertising phase, can I use the radio for some private tasks? en-USTelligent Community 13Wed, 13 Aug 2025 13:37:14 GMThttps://devzone.nordicsemi.com/thread/545537?ContentTypeID=1Wed, 13 Aug 2025 13:37:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d4503dfa-352e-4afe-847b-88f3eb236db6Sigurd<p>Hi!</p> [quote user=""]Can Timeslot be used during the advertising phase?

Within one connection interval, approximately how much idle time (Timeslot) can I request to perform private tasks? Is this duration stable? Is the length of granted time consistent each time a request is made?[/quote] <p>There should be a few ms left for the timeslot. But&nbsp;<span>it&#39;s variable and not guaranteed to be consistent, as <a href="https://docs.nordicsemi.com/bundle/sds_s140/page/SDS/s1xx/multilink_scheduling/timeslot_api_timing.html">Radio Timeslot API timing-activity is scheduled independently of any other timing activity, hence it can collide with any other timing-activity in the SoftDevice.</a></span></p> [quote user=""]Do the nRF54 series and nRF Connect SDK support the Timeslot functionality and its related APIs?[/quote] <p>Yes.
