Very clear, thanks! After adding scheduler to my project I can clearly see more stable timings in current consumption and also some current peaks are a little bit reduced!

Hi Davide

Yes, you are correct, the purpose of using the scheduler is to have your code execute in the main context, which is the lowest priority. The motivation for executing code in the lowest priority is to not let your code execution block other tasks that need to run with minimum latency. When you i.e. get a callback from the softdevice which has ARM priority 3, execution of that callback handler will block other softdevice callbacks. It is therefore a good practice to call the scheduler instead of executing a long task in the callback handler. An introduction how the priorities work is given on these threads (1) (2).
