LEDnet bluetooth control via OpenHAB

I have to create some smart home app for my customer who bought a house last month.
Today I’ve found some bluetooth lights - named as LEDnet which I can easy control via app from Apple Store. However I would like to control them using Openhab. Should I buy a type of dongle like Bluegiga? Or it’s even not possible?

Thanks for any suggestions.

I would stay away from bluetooth and go the zwave or wifi route, if was you.
