Hi HN, this is Jakub, founder of Estimote, Inc. (YC S13).

We just released a new revision of our Location Beacons. We implemented new, low power Nordic nRF52 chip and extended range to 200 metres (+10dB).

Beacons can simultanously advertise both iBeacon and Eddystone packets as well as telemetry & sensor data + they have built-in GPIO slot.

There is also 1Mb EEPROM, so you can read/write data directly in the beacon.

You can read more on our blog: http://blog.estimote.com/post/149362004575/updated-location-...

I will be more than happy to answer any questions here.
