hi, just got triggertrap mobile dongle for my em-5. how this thing suppose to work? i've connected it to my phone and i can see there is some connectivity. when the lcd goes dim from no interaction i press the big red button in the app the lcd becomes full bright, but there is no shutter release. what am i doing wrong here? i've set the camera to manual focus and my phone is nexus 5, so the android os is not an issue. thanks in advance.
