How to get BP data from external blood pressure devices

Hi Guys,

I'm unable to read data from bluetooth enabled external devices through bluetooth i'm using using standard  GATT services.

service uuid "00001810-0000-1000-8000-00805F9B34FB"

Error which is showing "Error while socket connecting: Not found"

Simple description of my code

Step 1: Scan Device
    Working fine
Step 2: Connect Device
    Working fine
Step 3: Create device bonding
    Working fine
Step 4: Reading data <Here I'm stuck >
device.connectToServiceByUUID("00001810-0000-1000-8000-00805F9B34FB", function(sock) {
                console.error('socket connected');
                var data= sock.ReadData();
            }, function(error) {
                console.error('Error while connecting socket: ' + error.message);

I'm using tizen bluetooth api
