Issues detecting my beacon on iOS app

I can’t see my beacons using Estimote iOS app or a BLE Scanner. Any help?

Are your beacons linked to you Estimote account? Do you see them in the Estimote Cloud (

Maybe they’ve run out of battery? How old are your beacons and what settings where they set to? Can you try detecting them with another device, to rule out the possibility that something’s wrong with your phone?
