Wired serial communication between ble nano 2 and arduino UNO


Actually my project is interfacing finger print sensor with the ble nano 2 and i have the arduino library for the finger print sensor which uses “softwareserial” for communication between arduino and sensor,But with the BLE NANO 2 It shows error and i came up with that the nano 2 didn’t have software serial port then how can i make the serial communication between them.I spend lot of time to make the serial communication work , but no success,So i need experts the support.Please give me a support.
