Scheduling time of Nimble stack

[WangJiacheng]

Hi, 

I’m trying to find out a free time slot between Nimble scheduled events.

I try to go through  all items on the schedule queue  global variable 
“g_ble_ll_sched_q” to find out all the scheduled LL events near future, 
function as
/********************************************************************************/
uint32_t ll_eventq_free_time_from_now(void)
{
  struct ble_ll_sched_item *sch;
  uint32_t cpu_time_now;
  uint32_t time_free;
  uint32_t time_tmp;
        
  time_free = 1000000000;
  cpu_time_now = os_cputime_get32();

  /* Look through schedule queue */
  while ((sch = TAILQ_FIRST(&g_ble_ll_sched_q)) != NULL)
  {
    time_tmp = sch->start_time - cpu_time_now;
    if  (time_tmp < time_free)
    {
        time_free = time_tmp;
    }
  }     
        
  return (time_free);
}
/********************************************************************************/

Does above function make sense to find out the free time at any given time 
point? or any suggestion to find out the free time slot between LL events?


Thanks,
