There are two things to consider: -
Do you have the new Clevershare 2 receiver app installed on your Android Module? To check this please open the Clevershare app, then open Menu and About, you should have at least v22.214.171.1243 but preferably 1.0.5.x.
With this new Clevershare 2G dongle it requires both the USB (black and white stick) receiver and the dongle to plugged into USB ports that the Android Module can see. Our recommendation is to plug the USB receiver into one of the Android Module (not mainboard as per the original Clevershare) USB ports and then plug the Clevershare dongle into any of the USB ports into the bezel of the Clevertouch.
Checking both of these points will ensure pairing commences.
