Hi,
I am using
- nRF52840
- SDK 15.3.0
- Keil IDE
- The soft device is S140
- JLinkRTTViewer for debug
I am using app_timer to control the LED On time.
the app_timer works correctly without SD event.
However, when an SD event (e.g disconnect) occurs, the LED is turned on for a shorter time than the app_timer value.
Question 1
Why does this happen?
Is it because app_timer priority is lower than SD event?
Question 2
Which timer should be used to be less affected by SD events?
Please advise.
