Windows bluetooth adapter firmware for nRF52840 dongle

[KevinResoL]

Are there any out-of-the-box firmwares that can turn a nRF52840 dongle into a generic bluetooth adapter (e.g. for connecting speakers, game controllers, etc) for windows?

Hi, 

Unfortunately, there is no such FW as your requirement on our (Nordic) side.

Thank you, but then can you recommend any documentation / reference on how create one?

Not possible either. There is an USB HCI example in zephyr - but it only works in Linux.

Windows drivers error out - I tested that - because the USB dongle does not support BT classic. Missing bt classic also prevents usage as "speaker".
