@shk It is pretty magic. In the lean days just after the #OG #dotcomboom I was at an #embedded company for a year, and I would have done just about anything for #ble instead of our home-grown #900mhz "thesis-style" protocol. Being able to follow a tag between the sensors is 100% one of the main products we brutalized ourselves trying (and failing!) to build. Now, it costs $20 for the tracker and $5 for the sensors, on my porch overnight, with batteries that last a year.

Anyone out there doing #900mhz #915mhz #HaLow #wifi experiments?
