LTE Beacons
1

App:

Estimote Version: Im running version 0.10.7 “The one with the Bugfixes” #FriendsFans
enableDebugLogging: true
setBackgroundScanPeriod: estimote default
Beacon range: 70mt max (and its sitting on my desk with all the testing phones in the same desk.
Beacon OS: A3.2.0 **Hardware Revision:**D3.4
Advertising interval: 427ms

Problem:
This is happening on a Sony Xperia M2 dual and Samsung Galaxy S5, same results in both phones, about 40 seconds apart from enter and exit.

I am running the same code in my Samsung Galaxy S6, and its running fine, it does not exit the region unless i move away or flip the beacon over

We describe this problem in great detail here:

https://github.com/Estimote/Android-SDK/blob/master/DOC_monitoring_scanning.md#dealing-with-many-onexitonenter-events

Long story short, some Android devices are simply better / more responsive in detecting beacons, and some will consistently “lose” the beacon signal. Can you try further reducing adv interval, see if it helps, and also playing with the backgroundScanPeriod and exitExpiration (maybe increase them a little bit), see if that helps?
