Troubling with integrating estimote iBeacon with IOS passbook

As per Apple's guidelines, I provided proximityUDID ie B9407F30-F5F8-466E-AFF9-25556B57FE6D to server end and the same is included in required json to create pkpass. I'm getting the same pass and add it to device passbook but it seems concept of iBeacon is not working as pass not comes to the device screen when entering within the beacon region.

I've tried different combinations like keeping the passbook in background, etc with negative expected result.

I hope someone surely guide me to make the passbook feasible with the estimote iBeacon.

Hi there—could you provide a snippet of your pass.json (remember to leave all the sensitive information out!) for me to take a look at? I'm mostly interested in the Relevance keys, i.e. "beacons", "locations", "maxDistance" and "relevantDate".
