I am working with an Arduino MKR WIFI 1010. It is powered by an USB (no Li-Po battery) to the current. (I am attaching a picture for better explanation). I saw that after some hours of working the LED (CHRG) of the Arduino starts blinking. This not affect my project but I am just worried that I am doing something wrong. I read a bit online but I didn't find a good explanation and also the datasheet did not help me. It states that the LED is related to the charging (but I am not using Li-Po external batteries) and that in particular the blinking is related to "input over-voltage, over-temperature, time fault". Does someone have idea?
I am attaching the sketch of my project (a simple Smart Garden) as well.
Did you ever find any sort of fix or explanation? I'm encountering the blinking as well, and when the CHRG LED blinks, my computer is unable to detect the Arduino on the list of COM ports to upload to.
No, I'm sorry. Since no batteries are connected and the voltage/current should be stable, the only reasonable thing is that LED blinks for "Timer fault" (whatever means). So, a first solution could be rest every tot hours (e.g. 24h) the board. But it is just an hypothesis and I don't know really why. I am still investigating. If someone find the solution, please will answer here
I am having the same problem with my unit. @lorenzoscavarda mine starts blinking after couple of hours, so resetting is not be a feasible option.
From what I can observe, there is a time difference when its powered through USB vs when it's powered through regulated 5V VIN pins. Forgot though which one takes longer though.
