You need to read Schedule handling library and Scheduler API docs.

Is there any sample application codes available ?

I checked many a files which use app_scheduler.

All the files calls " APP_SCHED_INIT(SCHED_MAX_EVENT_DATA_SIZE, SCHED_QUEUE_SIZE);" and then calls "app_sched_execute();".

Is the above said things are sufficient or we need to do anything else.

In my current approach, I am using the following priorities in addition to softdevice.

1. App_timer (Soft RTC & Reads switch ) assigned priority 2

2. SPI flash uses priority - 4

3. Sensors (TWIM & GPIO interrupt) -- 2

4. ADC -- priority - 3

5. Clock is assigned priority - 6.

Will changing the interrupt levels help me?

thanks & regards,

Thanks for prompt reply.

Let me try the scheduler approach.

You need to adhere to the SoftDevic specification's Interrupt priority levels.

I then suggest you use Priority 7 and use the app_scheduler to schedule your tasks, there you can set priorities for the individual tasks where they will still execute in priority 7.
I believe the underlying HW drivers use prio 6, so that they can execute whatever they need to, when they need to. Use the HW driver's callback function to schedule your tasks.

If you don't have very tight timing requirements, you could use the app_scheduler and schedule all your functions through the app_scheduler. You can even change the configuration of the app_timer library to schedule it's callbacks through the app_scheduler.
