Questions about APP_TIMER of nrf52832_SDK_15.3.0？

[Mars Zhang]

Hi,

#define TIMEOUT_INTERVAL               2000            // Two second.

     Sometimes starting app_timer_start(motTimeout_trigger_time_id, APP_TIMER_TICKS(TIMEOUT_INTERVAL), NULL), the interrupt is executed immediately, 

and it does not take two seconds.How to solve this problem?

Hi Jørgen, 

I try to replace the source file app_timer.c with app_timer2.c and drv_rtc.c, but compilation error.

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrf_sortlist_add (referred from app_timer2.o).
.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrf_sortlist_next (referred from app_timer2.o).
.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrf_sortlist_peek (referred from app_timer2.o).

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrf_sortlist_remove (referred from app_timer2.o).

Where are the following functions defined?
