request for review of app_timer2 backport to SDK14.0

[Allen]

Hello,

We are in production with a nRF52832_xxAA device using SDK 14.0

Recently we started experiencing some timer anomalies. It appears that others have also had problems with app_timer. The new app_timer2 was introduced in SDK 15 and is now the production timer library in SDK 16.

I backported app_timer2 from 15.2 to 14.0. A patch containing the backport modifications is attached. Perhaps someone could unit test app_timer2 with SDK14 and this backport. This did not fix our problem so I need to verify I did not make an error in translation.

Hi,

I looked over the patch, and it seems fine to me, however, I cannot test it with the application since I do not have your project available.

Are you facing the same issue that you had with the old app_timer, or are you not able to make the app_timer2 work with SDK 14 at all? From the changes you have made, app_timer2 should clearly be the one used. If everything else works as expected, and you still see the same issue, we need to look into this deeper.

Best regards,
Jørgen

Thank you Jorgen,

I was hoping you had access to the unit tests used to verify the new implementation. In fact, adding unit tests to the SDK is a great idea.

Best Regards,

Allen

Were you able to confirm that apptimer2 backport resolved issue for you? We are facing similar situation.
