General issue report

https://components.espressif.com/components/espressif/led_indicator https://docs.espressif.com/projects/esp-iot-solution/en/latest/display/led_indicator.html

if i define a looped Blink: like this one:

https://github.com/espressif/esp-iot-solution/blob/6359293fbe0727767bd3431c26e33044c3144057/components/led/led_indicator/src/led_indicator_blink_default.c#L15

then i call led_indicator_stop, then it is that the LED is on or off randomly. depending if it was in the on or off state when the stop came in.

the Customer of a stop await that the LED is off in any case.

any solution ?

Thanks, Franz

i found a possible Solution:

after Init start a lowest Prio looped OFF, and never stop it. 

when the blinking ends the lowest prio off jumps in.

You are correct. The 'stop' control logic doesn't actually turn off the light; it simply stops controlling the light. If you want to turn off the light when stopping, you can use the led_indicator_set_on_off function. Manually set the light to the off state during the 'stop' operation.
