Slight error in migration document found here:
infocenter.nordicsemi.com/index.jsp
NRF_BLE_OBSERVER(m_hrs_ble_observer, BLE_HRS_BLE_OBSERVER_PRIO, ble_hrs_on_ble_evt, m_hrs);
Should be:
NRF_SDH_BLE_OBSERVER(m_ble_observer, APP_BLE_OBSERVER_PRIO, ble_evt_handler, NULL);
NRF_SDH_BLE_OBSERVER - needs SDH_ in there. This is also wrong in the "Manually register the application as a BLE observer" example code.
