The S130 supports up to 8 concurrent connections as a central and peripheral as well as other features that is not present on the S120. See the S130 v2.0 Product Specificaton, found <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s130.sds/dita/softdevices/s130/s130sds.html?cp=3_7_2_0">here</a>.</p> <p>Best regards</p> <p>Bjørn</p><div style="clear:both;"></div>
