Unable to turn of the power state LED

[roderik-maker]

I have succesfuly compiled and uploaded the SY6970 example (and added the PMU.disableStatLed(); line to setup) but the green LED continues to flash, am I doing something wrong, or have I run into a bug?

The S3 Long is a great module but the bright flashing green led makes it un-usable for my use case. Worst case, can I just snap the led of the board?

Thank you in advance!

Ps. here is the "SY6970_Example.ino" file I am building

This LED light is the charging indicator for the SY6970. It will not light up when used solely with a battery. When the battery is not connected and the device is powered by USB, the green LED will flash. During charging, the green LED will stay on continuously. You can disable this LED function in the SY6970's registers.
