Question [Q] GPE - Polar H7 (Bluetooth smart) hart rate monitor

I'm running GPE on my Moto G. Today I've received my new Polar H7 (Bluetooth Smart) hart rate monitor. It works well with my Nexus 7 device (running CM10.3) and Polar Beat app.

The Bluetooth device isn't detected in any fitness app on my Moto G with GPE but my wifes Moto G with stock firmware detects it properly.

Is the GPE not supporting Bluetooth Smart 4.0 technology? Is this a bug?
