Get heart rate data over bluetooth with MATLAB

I am trying to read heart rate data from a POLAR H7 bluetooth device with ASUS BT400 dongle.

Device is paired allready with my computer.

I can see it from MATLAB

b=instrhwinfo('Bluetooth')
b = RemoteNames: {2x1 cell}
    RemoteIDs: {2x1 cell}
    BluecoveVersion: 'BlueCove-2.1.1-SNAPSHOT'
    JarFileVersion: 'Version 3.3'

b.RemoteNames
ans = 'Polar H7 1001A1'
      ''

But I can't see how many channels it has

instrhwinfo('Bluetooth','Polar H7 1001A1')
ans = 

           RemoteName: []
             RemoteID: []
ObjectConstructorName: []
             Channels: []

Neither open any channel

bt = Bluetooth('Polar H7 1001A1',1)

Bluetooth Object : Bluetooth-Polar H7 1001A1:1

Communication Settings 
  RemoteName:         Polar H7 1001A1
  RemoteID:           btspp://0022D01001A1
  Channel:            1
  Terminator:         'LF'

Communication State 
  Status:             closed
  RecordStatus:       off

Read/Write State  
  TransferStatus:     idle
  BytesAvailable:     0
  ValuesReceived:     0
  ValuesSent:         0

fopen(bt)

Error using icinterface/fopen (line 83)
Unsuccessful open: Cannot connect to the device. Possible reasons are another
application is connected
or the device is not available.

There is an open post on matlabcentral http://www.mathworks.com/matlabcentral/answers/119338-how-can-i-read-heart-rate-data-from-a-polar-h7-bluetooth-device

But I could not find anything relevant.

Can anyone help ?

Regards

Saddly, the answer is MATLAB supports only BLUETOOTH SPP PROFILE ...

If you check the port of the Bluetooth device in Device Manager, you can use the following code to open the port and access your Bluetooth device.

port=serial('COM40','BaudRate',57600);
fopen(port);
