I can attest coming across the same issue recently: disconnect in case of weak signal and never connect again, staying in the green light blinking mode. Running OS 1.1.0 for a few months. I also observed a little different behavior which I would like to draw attention to, I described in another post: Boron thinks it's online, console disagrees.
I’m about to place an order on 100 Borons for our pilot run of connected devices and it’s important to know we can proceed with the launch confidently as the product’s successful reception depends on it.
