Combine multicentral and muliperipheralhttps://devzone.nordicsemi.com/f/nordic-q-a/63613/combine-multicentral-and-muliperipheralDear All: Our team are ready to develop a project with multicentral and multiperipheral The project topology image lists as follow: I want to ask how many ram it will cost at least, Does nRF52832 can fullfill those requirements? Thanks in advanceen-USTelligent Community 13Sat, 11 Jul 2020 01:11:36 GMTRE: Combine multicentral and muliperipheralhttps://devzone.nordicsemi.com/thread/259539?ContentTypeID=1Sat, 11 Jul 2020 01:11:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:009f7ee3-fb69-4bf1-b937-076a36ee7b23Tommy_Li<p>Thanks for your kindly reply</p><div style="clear:both;"></div>RE: Combine multicentral and muliperipheralhttps://devzone.nordicsemi.com/thread/259455?ContentTypeID=1Fri, 10 Jul 2020 13:08:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:54f52f90-9f35-4d79-9e99-de881ee60976tesc<p>Hi,</p> <p>This should be possible on the nRF52832, yes. The s132 SoftDevice on the nRF52832 can handle up to 20 concurrent connections, so the 7 connections are well within limits.</p> <p>A quick check based on the ble_app_multirole_lesc_s132_pca10040 example indicates 2 peripheral + 5 central gives SoftDevice RAM requirement of 0x4A20 = 18976 bytes, or around 19 kB. This may vary depending on size/number of characteristics, etc., and application side RAM requirements are not included.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
