Help! Not found my beacons

Stop trying my beacons by one month and now does not detect from an iphone or android

My beacons are missed? or I should do some previous settings ...

The only thing I could have done is to update the app on both devices Estimote

Hi Diego,

Do you remember what was the last known battery level or your adertising interval/broadcasting power settings? If you cannot see beacons on any device, it's most likely the battery. You can replace it after cutting the enclosure open - drop me a line to if you need any help with that. Also, we will send you new enclosures for free :)
