what do I need to do so I can make the arduino receive data from the bluetooth?
Threaten to take a sledgehammer to the device if it doesn't behave. I'm sure that the bluetooth device will shape right up.
If that should fail to work, I suspect that Mr. Google has other advice that might be more useful.
You know, stupid sh*t like how to connect the device to the Arduino, how to set up a HardwareSerial instance or to create a SoftwareSerial instance so that the Arduino can talk to the bluetooth device, and get data from it.
