https://devzone.nordicsemi.com/f/nordic-q-a/3683/s110-observer-and-broadcasterHi, just for understanding what soft device do i have to use when i want to build an application wich use observer role and broadcaster role at same time? Can i use S110 Timeslot api to do this at the same time or have i to use S130?

I&#39;m sure you could use the timeslot api, but surely it would be easier to use the functionality already provided by the S130 SD?</p> <p>(the broadcaster / observer roles could be implemented &quot;relatively simply&quot; using the raw RADIO API, however getting the timings and other behaviour correct as per Bluetooth standard would involve some work, and you may have a higher testing burden to show compliance with the Bluetooth standard)</p> <p>(the timeslot api is used to allow you to perform operations that disable the soft device interrupts for a short period of time. This can be used to (re-)implement additional radio protocols or implement timing-critical IO. It can&#39;t be used to timeslice the functionality of the softdevice.)</p><div style="clear:both;"></div>
