We would suggest to use nRF52832 (256kB flash) or nRF52811 (192kB Flash) for that purpose.&nbsp;<br />The reason is that the nRF52810 only has support from S112, S113 and S132 softdevice. In these only S132 has central role but the latest version that S132 supports nRF52810 is v5.1.0 which is quite old.&nbsp;<br /><br />If you use nRF52811 you can use S122 central only softdevice which needs smaller flash size (122kB) compare to S132 or S140.&nbsp;<br /><br /></p><div style="clear:both;"></div>
