Hi!

There's this awesome crowdfunded project called Angel sensor. It's a wristband to check heart rate and other variables, the interface is just LEDs, sound and vibration (no display though). But I think it'd be great if it could communicate with something similar to sports tracker (which works fairly well in N9).

They'll support iOS and Android, but they promised it'll work with any PC or device with bluetooth 4.0.

I understood that N9 has bluetooth 4.0 but it's not enabled. The specs say it's BT2.1.

So, my questions are:
+ Is there any driver or trick to enable BT4.0 in Nokia N9?
+ Can the BT2.1 of the N9 communicate with the BT4.0 of the Angel sensor?

I'm aware it'll require sometime to actually code something cool out of it but there're endless possibilities (mostly related with sports and making pretty plots *-*). I've been just a user for quite a while and I'm very happy with the default apps and a couple extra ones, so I didn't have the need to go any further, I hope this will be fun
