It is however soon possible for a peripheral to be aware of other centrals when in a connection, see <a href="https://devzone.nordicsemi.com/question/27990/can-peripheral-find-out-if-another-potential-central-is-present/">this thread</a>.</p> <p>An iphone can however take the role of either central or peripheral. You could configure the device to be a central and then number of iphones to be a peripherals. A nRF51 device with S120 central softdevice can maintain up to 8 simultaneous links with eight different peripherals.</p><div style="clear:both;"></div>
