Hello I recently updated my project from 17.0.2 to 17.1.0.
I found a problem while checking the full functionality after the update.
In my project, there is a buzzer for an alarm, and it was confirmed that the operation time was doubled.
I'm using app_timer2 for buzzer control, I ask if there are SDK fixes related to app_timer2.
In the code I wrote, it is enough to input the buzzer operation time by 1/2, but I would like to know the fundamental solution.
I'll be waiting for the reply.
I've modified the two examples by adding a callback handler to the app timer module, so that I can toggle a GPIO when the app timer starts and when it has completed in the handler. This lets me measure the elapsed time of the app timer.
Comparing the two:
SDK v17.02 ble_app_template_17_0_2.zip:
Using the debugger I check the timeout parameter that is passed to app_timer_start() and see that it's set to 100 (ms).
By measuring the toggling interval of the GPIO, I see that the timeout time of the application timer corresponds to the timeout that is passed to app_timer_start():
SDK v17.1 0 1856.ble_app_template.zip
Using the debugger I check the timeout parameter that is passed to app_timer_start() and see that it's set to 100(ms):
By measuring the toggling interval of the GPIO, I see that the timeout time of the application timer corresponds to the timeout that is passed to app_timer_start():
Result: In both cases I can see and verify that the timeout is set to 100 ms.
I could therefore not reproduce your observations.

hello
It's terribly strange that you can't verify.
It is also confirmed with LED control, not PWM control like your example.
Please check the picture and code below again.
