Bleam scanner is an inverted Bluetooth low energy (BLE) beacon communication protocol. In the inverted communication scheme beacon serves as a scanner, taking this role from a phone that in its turn is responsible for advertising. The main benefit of such a design approach is its ability to function extensively in the background, monitoring RSSI levels. See: https://github.com/Connax-Oy/Bleam-Scanner-2
Nice idea - but the "Unsolved problem" seems to be a showstopper:
It's not really a showstopper, but a point to consider. Currently we've been using this system on one of the gas stations and it seems that with ECO mode beacons can survive more than a year. Let's see, maybe in a new version of the protocol it will be solved even further. I hope guys can comment more on that.
Yes, this problem is not a showstopper. The main thing we encountered was a faster discharge of beacons in the outdoor at a temperature of -30. There are several solution options here: as even greater code optimization and/or the use of more outdoor protected beacons

On what battery?
How does that compare to "conventional" beacons?
eg, this one claims 1 year - and also does temperature logging:
We use RuuviTags with CR2477, they dwell approximately 11 months when used frequently.
