Question 1I know I can control the LEDs by writing ASCII strings to /sys/class/leds/aw2013_right_red/brightness

I wanted to know the range of values I can write. I tried to read from /sys/class/leds/aw2013_right_red/max_brightness
but got Permission Denied.

Can you tell me the range of Brightness values please.


Question 2
I have also teste the Red LED Blink.
Is it possible to change the speed that the LED blinks so there is 1 flash per second


Hardware is DSJ-HISZ1A10280526
Serial Number 8474aa0d Body Camera

Thanks
Roger
