It works okay: it drops around 10% of the data due to reception issues, but I think it might be related the parameters I have set for the gain on the software defined radio.
I need to position the receiver to have line of sight.
I use Bluetooth for lights which actually does work through the stone about 10 meters away, which doesn't make sense to be, but that's been my experience.
