Unable to detect beacons on estimote app

Hi team,
I have a set of 9 beacons. Even if i place the beacons next to my phone with location and bluetooth on i am unable to detect any beacon.
Kindly let me know if i am missing out something.
Thanks in Advance.

Did you try with Estimote App? (https://play.google.com/store/apps/details?id=com.estimote.apps.main)
