I saw the article that "How to change the proximityUUID using Estimote SDK?".
So I tried to modify my beacon's UUID (major, minor) value .
I created ESTBeaconManager object and message 'startRangingBeaconInRegion:' with ESTBeaconRegion object
In 'beaconManager: didRangeBeacons: inRegion:' method, I messaged 'connect' ESTBeacon object.
After that, I called 'writeProximityUUID:completion:' to it.
But I can't get anything about changing beacon's info.
I used Estimote demo app to modify UUID. But, 'Saving UUID failed' error occurred.
My beacon's info
OS : Estimote OS A2.1
Hardware revision : D3.3
SDK version : 2.0
What is the problem in my procedure? I want to know that.
