So my HAT has been working great, but I noticed the other day that L1 and L2 are flashing white pretty steady about 5-10 seconds. I also have lost any response from S1 and S2, been using the same battery and it checks out OK, but swapped to another known good one and still same problem. I don’t see anything that says what flashing white LEDs means, only red, yellow, and green.
The UPS portion does work, but I would like to understand what’s going on with the board that could have caused the LEDs and buttons to go wacky like this.
