https://devzone.nordicsemi.com/f/nordic-q-a/60151/ble-observing-with-softdevice-s112Hi everyone： My case is to reveice some useful information form beacon device, but I have no ideal that is the softdevice s112 support observing so far ？ The s132 softdevice is too large for 194K flash room...en-USTelligent Community 13Tue, 14 Apr 2020 09:35:26 GMThttps://devzone.nordicsemi.com/thread/244374?ContentTypeID=1Tue, 14 Apr 2020 09:35:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:04926614-643d-4d68-a528-4dacddb3631eVidar Berg<p>Hi,</p> <p>You have to use s132 v.5.1.0 (<a href="https://infocenter.nordicsemi.com/topic/comp_matrix_nrf52810/COMP/nrf52810/nRF52810_ic_rev_sdk_sd_comp_matrix.html">combability matrix</a> &amp; <a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/the-s132-v5-1-0-is-now-production-tested-on-nrf52810">blog post</a> ) to support the observer role. I don&#39;t think you should have any problems fitting this all in flash if you are making a simple beacon scanner. s112/s113 will not support this role as that would have required a significant increase of its flash footprint.&nbsp;</p><div style="clear:both;"></div>
