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
Hello! Perhaps the section naming is overdramatised. The problem of power consumption is an ongoing problem for all battery-powered active beacons. If one was to put this project to test in an environment of a crazy throughput, say a mall on Black Friday, or a busy highway, they would really need to consider additional power saving options, and this section meant to encourage developers to come up with solutions. A regular everyday setting would not warrant immediate power saving measures, although any kind of power saving is always useful.
I will reiterate this in the project description. Thanks for the feedback!

On what battery?
How does that compare to "conventional" beacons?
eg, this one claims 1 year - and also does temperature logging:
