Sounds like <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.3.0/ble_sdk_app_nus_eval.html?cp=4_0_3_4_2_2_19">ble_app_uart</a> and <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.3.0/ble_sdk_app_nus_c.html?cp=4_0_3_4_2_0_2">ble_app_uart_c</a> are good starting points. In these the ble_app_uart is the peripheral and has the server, while ble_app_uart_c is the central and is the client.</p><div style="clear:both;"></div>
