Bluetooth Audio (Bootcamp-windows 10) not working with Bose wireless speaker

I have windows 10 on bootcamp version 6 in my macbook pro (late 2013 model, 13 in)

I was able to pair my mac with the bose soundlink mini 2 wireless speakers, but when it comes to windows 10 (bootcamp) , the first time it successfully pair and then there is no audio from the speaker. After the first attempt, the connection is always in "paired" status, but no audio.

I checked on web and found the below links which tells you its an age old problem with no fix from apple.

Its 2015, and bluetooth connectivity to wireless speakers is a given. But that does not seem the case.

I am not sure which dirver to install, if it has to be done manually , since all it says in the hardware properties is "apple broadcom built-in bluetooth driver".

Anyone else faced a similar issue or is it just me ?
