SEN0344 Code Issue

Hey, I'm trying to use the library and code along with the HC-05 bluetooth module. When I don't import the module I get the HR and SPO2 values.

As soon as I import the SoftwareSerial library, I don't get any output at all.

Here's the code: 

#include <DFRobot_MAX30102.h>

DFRobot_MAX30102 particleSensor;

#include <SoftwareSerial.h>

SoftwareSerial EEBlue(2,3);
