Default Polar IWL (WearLink) Bluetooth Heary Rate Monitor and Nexus 5 Any success?

So I though it might be the battery in my device, so i replaced it... still no go.

The polar wearlink bluetooth heart rate monitor will not even show up on my nexus 5.

Any ideas? any known bluetooth issues with other devices?

Anyone else have this issue?

I'm on stock rooted nexus 5.

Link below to the polar site for the product.

Thanks all,

P.S.- the polar wearlink appears to be bluetooth 2.0, it should still work on the nexus 5 bluetooth 4.0 right?
