Lenovo mirage solo - how to connect bluetooth controller/gamepad

HI, I’m trying to pair bluetooth controller for VR, exactly esperanza emv101, but it has option for gamepad, and it is working with almost all android devices. I have been using this controller fine in gearvr and ue4 recognizes its input ok.
Problem is I can’t find a way to pair this device with lenovo mirage solo.
Have somebody succeed pairing some gamepad with mirage solo by bluetooth?
Regards
Daniel
