Can't get heart rate from Zephyr HxM BT on Endomondo & Z10

App Version - Endo Pro
Phone - BlackBerry Z10 10.1
Carrier - Rogers
HRM - Zephyr HxM BT

Hello,

I have received my new Zephyr HxM heart rate monitor, and I was able to get it paired with my Z10 very easily. After that though, even after a reboot, I cannot get Endomondo to display heartrate, I only get a heart with an x on it. I have properly charged the Zephyr, and have run the band under water prior to putting it on. I have rebooted the phone many times not to avail.

Is there some known problems with running it on the Z10? Anybody with the same setup?

I am quite dissappointed...
