nrf52840 app_timer2.c 322 line,APP_TIMER_SAFE_WINDOW timeout

[kun]

I used multiple software timers, all of which were timed repeatedly. After running for a few hours, it appeared ASSERT(app_timer_cnt_diff_compute(drv_rtc_counter_get(p_instance), drv_rtc_compare_get(p_instance, 0)) < APP_TIMER_SAFE_WINDOW); overtime
Why here, how should I investigate

Hi!

What SDK version are you using?

How much over APP_TIMER_SAFE_WINDOW are you ?

[xueyi]

The SDK  version is 17.1.0. We use the default APP_TIMER_SAFE_WINDOW is APP_TIMER_TICKS(300000)

1) Could you print the value of app_timer_cnt_diff_compute(drv_rtc_counter_get(p_instance), drv_rtc_compare_get(p_instance, 0)) ?

2) Do you have any log output from when this happened?
