https://devzone.nordicsemi.com/f/nordic-q-a/15222/pros-and-cons-s130-vs-s110-vs-s120Hi, We are assessing the pros and cons to port our software to work on S130. We are currently using S110 (Peripheral) and S120 (Central) on nRF51822 rev.3. Based on the specifications the Flash usage on S130 is more than two others, but the RAM usageen-USTelligent Community 13Wed, 20 Jul 2016 07:13:15 GMThttps://devzone.nordicsemi.com/thread/58139?ContentTypeID=1Wed, 20 Jul 2016 07:13:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5c59d833-2ccf-4dcd-8bd3-b299b12bdad2Petter Myhre<p>Great! Then I would appreciate if you could accept my answer. Thanks.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/58138?ContentTypeID=1Tue, 19 Jul 2016 16:10:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e789208b-aad7-4cb7-9181-a1c614ace19aEhsan<p>Thanks Petter. It is more clear now.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/58137?ContentTypeID=1Tue, 19 Jul 2016 15:37:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3b22de92-a1b0-431c-8618-8cf4803c94eaPetter Myhre<p>I confirm. The thing is that with S130 v2.0 the RAM usage depends on a number of things, the number of links, the number of TX and RX buffers on these links and so on. So the minimum RAM usage is very low, but to figure out the actual ram usage you need to look into the RAM usage with a configuration that fulfill your requirements.</p> <p>The current consumption of S120, and only using S130 only as a central should be very similar. The same with S110, and using S130 only as a peripheral. Please see <a href="https://devzone.nordicsemi.com/tutorials/11/">this</a> for how to calculate current consumption.</p> <p>There are no new releases planned for S110, S120, or S130. So we are not working on any potiential modifications for the S130.</p> <p>If you want new features you should consider moving to nRF52.</p><div style="clear:both;"></div>
