RE: Best way to reload an app timer with a new value?

The solution to this is to use the event scheduler so that the timer actually stops before it is re-started (as app_timer_stop and app_timer_start will now be executed from the main context).

Event function:

void reset_idle_timer_event(void * p_event_data, uint16_t event_size)
{
reset_idle_timer();
}

Scheduling event:

// Reset idle timer
err_code = app_sched_event_put(NULL, NULL, reset_idle_timer_event);
APP_ERROR_CHECK(err_code);

Reset timer function:

void reset_idle_timer(void)
{
    uint32_t err_code;
    
    // Stop timer
    err_code = app_timer_stop(m_idle_timer_id);
    APP_ERROR_CHECK(err_code);

    // Start timer
    err_code = app_timer_start(m_idle_timer_id, APP_TIMER_TICKS(idle_timer_val*1000, APP_TIMER_PRESCALER), NULL);
    APP_ERROR_CHECK(err_code);
}
