I tried to pair Fenix 2 and Android Connect program. 
When I click on Pair device window - I can see on the pair connection code and Connect searching and searching for device. 
In 1-2 minutes I've got message Connection timeout. - "Timeout while connecting" 
Please watch video example -

Any idea how to fix this problem? 
P.S. I tested my smartphone
I connected to my Bluetooth headphones without problem. This mean - Bluetooth connection is ok.  :-)
Connection via USB cable - works great.
