Getting manufacturerData from custom uuid device

Hello Everyone!!

I have been trying to get advertisement data from a custom ble device(with nRF52832 chip) that has been advertising ambient pressure every 5 minutes.

When I use the below code snippet ,

// Start scanning
packets=10;
NRF.setScan(function(d) {
  packets--;
  if (packets<=0)
    NRF.setScan(); // stop scanning
  else
    console.log(d); // print packet info
});

I could get the following

BluetoothDevice: {
  "id": "90:6d:0f:4b:89:b4 public",
  "rssi": -76,
  "data": new Uint8Array([x, x, x, xx, x, x, x, x, x, x, xxx, xxx, xx, xxx, xxx, xx, xxx, x, xx, xxx, xx, x, x, xx, xx, xx, xx, xx, xx, xx, xx]).buffer,
  "shortName": "xxxxxxxx",
  "services": [
    "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
   ]
 }

But I could not get the manufacturerData that has been advertised, which can be seen in "nRF Connect" mobile application.

Simply I could not get the manufacturerData of 30 bytes, which is again shown in Raw data: part in mobile app.

Any help is greatly appreciated

Thanks in advance!!
