Search for surrounding beacons

Hi everyone,

I just started playing with the Estimate iOS SDK but I am unable to search for surrounding beacons (list all beacons near the device).

Do I need the ESTDeviceManager class? (startDeviceDiscoveryWithFilter?). How do I implement the ESTDeviceFilter protocol?

Best regards,

I have having same issue. Using platform and Can not see any Eddystone URLs.
Thanks,
J
