Estimote app keeps connecting and disconnecting from Location Beacon

I’m using iPhone 6 with iOS 12.2.
When I launch the Estimote app it detected the Location beacon but when I try to connects to it, the app will keep connecting and disconnecting from the beacon. It will only stay connect for like 1 second then disconnect the cycle keeps repeating.

I have tested the bluetooth it is working as I’m able to do sharing with another phone.
Please advise what is the cause and how to resolve it.


Have you done any testing with another device?
