Read Data from unknown Bluetooth Device while communicating

I am trying to figure out how the FORA d15b blood pressure monitoring system communicates via Bluetooth. I want to be able to eventually write an Android app that can receive blood pressure data from the device.

More specifically, I want to know the exact data to send to the device in order to request blood pressure information. I also want to know the data that the device sends out. However, I don't even know the format of the data being sent/received.

I know that FORA has a PC app that can communicate with the d15b device via Bluetooth but I don't know what information its sending/receiving over Bluetooth, and that's what I want to know.

Here is Bluetooth information I know about the d15b device: Bluetooth Carrier Frequency: 2400MHz to 2483.5MHz Bluetooth Modulation Method: GFSK, 1Mbps, 0.5BT Gaussian Transmission Power: +3dBm to –20dBm; Power control 4 stage Receiving Signal Range: -88dBm to -20 dBm Receiver IF Frequency: 1.5MHz center frequency Maximum Data Rate: Asynchronous:723.2kbps/57.6kbps; Synchronous: 433.9kbps/433.9kbps

I'm struggling to even find a starting point. Any help is appreciated! Thanks in advance.

I am familiar with C, Java, and Arduino if that helps at all...

NOTE: Unfortunately, I am new to Bluetooth. After doing some research, I am still pretty clueless on how to solve this problem. In the title, I say unknown Bluetooth device because I just want to be able to read what I/O of an unknown Bluetooth device, which in my case happens to be the d15b that I know nothing about. Sorry if the question has been addressed already or if this is an inappropriate place to post this question. I wasn't sure.

Bluetooth data is encrypted. So it's not possible to hack it easily. Forget it.
