This time of year, when I haven't had the bike out for quite a while, when I'm in the garage my BT always has the green light on solid, no flashing. I guess it is doing its thing. But, once in a while, just to try and check it in some manner, I will unplug it from the wall outlet in the garage. Just a few seconds later I will plug it back in. The red light will come on for anywhere from 10 to 60 or so seconds, then the green light starts flashing and within a minute, sometimes maybe three minutes, the flashing green goes to solid green. All good. I guess that from time to time the BT kicks in for a short period of time then goes to solid green but I've never seen that happen. Every time I'm going in or out of the garage I look at the BT and its always the solid green light on.
