If you can get a short green flash, your TouchPoints™ simply need to be "hard-paired" to your phone once. Open your phone's settings menu to the Bluetooth section. Then turn on your TouchPoints™ so you see the short flash. Your TouchPoint™ is technically on and it should show up for you to be able to "hard-pair."
Once you pair it through the Bluetooth menu you should be able to go to the TouchPoints™ app and connect to the TouchPoint™ without any issue. This will also clear the short flash so that going forward your TouchPoints™ will flash green if pairing and show a solid green light when paired.
