How to get the Serial Number of the Remote Device over Bluetooth?

Question

In my application, I discovered bluetooth devices and thus got the following ---

• Name of Bluetooth Device.
• Hardware address of Bluetooth Device.

This is done by getting BluetoothDevice object for each discovered device and calling object.getName() and object.getAddress().

I also want to get the Serial number of each discovered bluetooth device.

I know to get the serial number of my own device as ---

android.os.Build.SERIAL

Many bluetooth low energy profiles provide a service called Device Information.
Assigned UUID: 0x180A
https://www.bluetooth.com/specifications/gatt/services/

Under this service there is a Serial Number String characteristic which can hold a serial number specific to the Bluetooth low energy device.
Assigned UUID: 0x2A25

This is optional though and not all BLE profiles will have it, and you have to connect to the device to retrieve this information.
