How to get rename bluetooth printer name in app?

I have used zebra ZQ110 SDK in my app. When I have a search device I have got zebra printer name in the Bluetooth list. But when I rename the zebra printer I have not got rename name when I again scan I have got old name of Bluetooth.

Under “Settings” go to Bluetooth and find an available device.

After pairing the device, tap on the gear to access the option to rename the device.

Now open my app again and search for available Bluetooth devices through ZQ110 SDK. Now I have got old Bluetooth name XXXN15-29-0114

instead of ZQ110.
