I have a Digi i.MX6UL starter kit and a HRM strapped to my chest. If I fire up bluetoothctl I get:  
root@ccimx6ulstarter:~# bluetoothctl  
[NEW] Controller 00:04:F3:06:D8:AF cc6ul [default]  
[NEW] Device 00:15:83:EC:AA:39 RWOODHAM2  
[NEW] Device 62:80:E1:00:7B:88 Geonaute BLE HRM  
[bluetooth]#  
[bluetooth]# connect 62:80:E1:00:7B:88  
Attempting to connect to 62:80:E1:00:7B:88  
[CHG] Device 62:80:E1:00:7B:88 Connected: yes  
Connection successful  
[CHG] Device 62:80:E1:00:7B:88 Paired: yes  
[Geonaute BLE HRM]# list-attributes  
[Geonaute BLE HRM]#

i.e nothing

I can get the Geonaute to work with a competitor product (so I think the chest belt is working OK), why not on yours?

#Version 5.41

On the competitor the version is 5.43 I think, so not so very different.
