nRF5_SDK_12.2.0.
app_timer_freertos.c
app_timer_stop() call xTimerStop/xTimerStopFromISR with timer_id parameter.
It seem to must use hTimer parameter.
sorry for late reply. I did not understand your question correctly. Are you saying that the app_time_stop function does not use the correct parameter, so it does not work?
When call app_timer_stop(), app_timer is seem to stop.
but If timer is cyclic-timer, associated FreeRTOS timer is running yet.
As a result, current consumption is high.
