The example projects use LED&#39;s extensively to indicate the state of the peripheral (advertising, connected, etc.) using the BSP.</li> <li>Use a longer advertising interval (higher value of APP_ADV_INTERVAL in the ble_app_bps project).</li> <li>Consider enabling the DC/DC. See <a href="https://devzone.nordicsemi.com/question/685/ldo-vs-dcdc-nrf51822/?answer=988#post-id-988">this post</a> for details.</li> <li>You can reduce the TX power (using <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s110.api.v8.0.0/group___b_l_e___g_a_p___f_u_n_c_t_i_o_n_s.html#ga0f1931af876bef39520c58de5ac060ca">sd_ble_gap_tx_power_set</a>). However this can increase the time the peripheral must advertise before the central picks up the advertisements, so it may not be a good idea.</li> </ul><div style="clear:both;"></div>
