https://devzone.nordicsemi.com/f/nordic-q-a/20006/turn-off-pwm-ledI have a BLE device that is using Nordic SDK 8.1 and uses PWM to control an LED. Now I want to turn the led off with PWM. To do this I set the duty cycle to 0 and printed to the led. Yet when I do this the led stays on. What could cause this?

I&#39;d like to not update everything if possible since it would take a while.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/77846?ContentTypeID=1Sun, 26 Feb 2017 17:03:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:eb4b8c45-fb49-4998-97cb-04fdfe500b95Daniel Wang<p>Try with a newer SDK, the old SDK 8 PWM library have a lot of bugs.</p><div style="clear:both;"></div>
