https://devzone.nordicsemi.com/f/nordic-q-a/11151/s13x-2-0-0-8-alpha-peripheral-connection-count-and-ram-formulaI just read the S13x migration guide .. have some work to do :(. I&#39;ll have to read it a few more times to get my head around the bandwidth configuration but it looks super useful. Two questions. Is the periph_conn_count parameter now working soen-USTelligent Community 13Wed, 06 Jan 2016 12:49:54 GMThttps://devzone.nordicsemi.com/thread/41792?ContentTypeID=1Wed, 06 Jan 2016 12:49:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b33e35d2-7947-4906-813e-eafcd76ddcc1RK<p>thank you - I did actually set the number of peripheral connection to 2 to see the delta memory and it dint&#39; break, but I didn&#39;t try to use the second one, it was just a memory test. I&#39;ll keep at 0 or 1 until the release notes tell me we&#39;re good for more.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/41791?ContentTypeID=1Wed, 06 Jan 2016 12:44:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5d4d544f-427b-4f94-a0ac-09af846f0a65Petter Myhre<p>Only one peripheral connection is supported. So you can set it to 0, or 1.</p> <p>The best advice is to read the app_ram_base value returned from sd_ble_enable() and use it.</p> <blockquote> <p>How confident should we be that minor revs to the softdevice won&#39;t need more RAM for the exact same config parameters? I&#39;d always be tempted to round it up a little bit to save having to do a firmware release because a minor softdevice revision wanted 16 extra bytes or something.</p> </blockquote> <p>Good question. We need to look into this. Will update soon.</p> <p>Unfortunately, the documentation will not be available in the Infocenter until the next SDK release.</p><div style="clear:both;"></div>
