Well Madhumati,
your flow looks good. It is similar to my flow I used with my sensorbug BT device last year. So basically the BT communication over Node-RED on netPI works on your unit.
The further communication is now a matter of attributes you can read from your mobile phone. But as I told you ... you need the GATT specification of a Bluetooth device to know which UUIDs can be read or written.
I am pretty sure that NOKIA will not tell anybody their secrets about the attributes in the phone that can be read. It is a consumer product and not an "open" Bluetooth product with a detailed specification a developer like you need. So in my eyes a mobile phone is not a good device to test Bluetooth communication and reading attributes cause of missing GATT list. You need a real Bluetooth sensor with open specification and then you read the attributes from it over Node-RED.
Thx
