The reason for the behavior is that the GATT module initiates a MTU exchange upon the event BLE_GAP_EVT_CONNECTED. When trying to enable notifications,the MTU exchange is ongoing,and hence,ble_nus_c_tx_notif_enable() returns NRF_ERROR_BUSY.

Enabling notifications when the MTU exchange has finished,solves the problem.(Upon the event BLE_GATTC_EVT_EXCHANGE_MTU_RSP).
