Use the USE_SCHEDULER parameter of the APP_TIMER_INIT() macro to select if the Scheduler should be used or not. This will be the case, for example, when stopping a timer from a time-out handler when not using the scheduler. Timers can be grouped together for organizing and linking. Features such as Linked timers, which allow for timers sequences and Voice notification required app to be running in foreground. Timers use scheduled toast notification which enable notifications to happen in background even if app is not running.
#Itimer app code#
Since the SWI0 interrupt is running in APP_LOW, if the application code calling the timer function is running in APP_LOW or APP_HIGH, the timer operation will not be performed until the application handler has returned. Setup multiple countdown timers for tracking activities. The actual timer start/stop operation is executed by the SWI0 interrupt handler.
#Itimer app software#
When calling app_timer_start() or app_timer_stop(), the timer operation is just queued, and the software interrupt is triggered. Both interrupt handlers are running in APP_LOW priority level.

List handling is done using a software interrupt (SWI0). Checking for time-outs and invocation of user time-out handlers is performed in the RTC1 interrupt handler.
