I use ble_app_hrs_rscs_relay to build a node which has both central and peripheral roles. I can do scan and adv, but when I add eddystone functions "nrf_ble_es_init(on_es_evt)" into the code, it return me an error calld fatal error. do anyone know what's wrong? also I have command out all old adv code.

/**
* @brief BLE Heart Rate and Running Speed relay application main file.
*
* @detail This application demonstrates a simple relay, which passes on the values it receives.
* By combining a collector part on one end and a sensor part on the other,
* the s130 can function simultaneously as a central and a peripheral device.
*
* The following figure shows how the sensor ble_app_hrs connects and interacts with the relay
* in the same manner it would connect to a Heart Rate Collector. In this case, the relay
* application acts as a central.
*
* On the other side, a collector (such as Master Control Panel or ble_app_hrs_c) connects
* and interacts with the relay in the same manner it would connect to a heart rate sensor peripheral.
*
* LED layout:
* LED 1: Central side is scanning. LED 2: Central side is connected to a peripheral.
* LED 3: Peripheral side is advertising. LED 4: Peripheral side is connected to a central.
*
* @note While testing, make sure that the Sensor and Collector are actually connecting to the relay,
* and not directly to each other!
