Hello Wojtek can you share any sample Peripheral code for SDK 11 prepared by you. It would be great help from your side. If you want i can share you my Email ID:- jayesh1.embedded@gmail.com Right now i am using soft device "s130_nrf51_2.0.0_softdevice" for SDK 11. But while debugging i am not getting yellow pointer on 1st line of Main routine infact i am not getting only yellow cursor. Am i using wrong soft device ?

Ok I was a bit wrong - it doesn't calculate number of timers initialized, but actually every APP_TIMER_DEF reserves ram for static timer instance.

But on what basis IDE automatically calculates number of timers, any idea Wojtek??

You are absolutely right. It's fixed now.

I think there is a typo at using the comparison expressions. Shouldn't it be "SDK <=9 to SDK >= 10" ?

There was a change in the application timer API from version 9 to 10. This change is explained in the Application Timer Tutorial. There also a Scheduler Tutorial that describes how to use the scheduler together with the application timer. The tutorials are written for SDK version 9 and 10, but is equally valid for version 11.

In short this is the changes you have to do when going from SDK <=9 to SDK >=10:

Create the timer ID with APP_TIMER_DEF().
APP_TIMER_INIT does no longer need the max number of timers a a parameter.

In addition, if you are using the scheduler you should initialize the application timer using APP_TIMER_APPSH_INIT().

I don't know about scheduler, but I think APP_TIMER_MAX_TIMERS is not needed as IDE automatically calculates number of timers used and reserve exact amount of memory needed to handle them.
