Using https://github.com/welbesw/iBeaconExamples I created an app that monitors for a specific UUID, as given in the source. It works perfectly when I use two iPhones, one as broadcaster and one as monitor.
When I however change the UUID to the one I set up my Gimbal iBeacon with (using Gimbal beacon discovery), it cannot find the beacon. Also when I register the UUID (which I specified in the "manage configurations" bit in the Gimbal Manager) in other apps such as BLExplr or Locate IB (Radius Networks) it can't be found. BLExplr does find the beacon's Bluetooth Service UUID (iOS iBeacon: How to get all of proximityUUID programmatically?), so it's definitely broadcasting...
Does anyone have an idea what could be the solution here?
