Hi,

New App Timer: examples\peripheral\cli

Old App Timer: examples\peripheral\twi_master_with_twis_slave (CLI with old APP timer is used in the example)

Hi Jakub, sorry for late reply. I looked on SDK15 files and it appeared that AppTimer 1 is used by default. AppTimer2 present in experimental subfolder. I tried to move to it by enabling

#define NRF_SORTLIST_ENABLED 1
#define APP_TIMER_V2_RTC1_ENABLED 1

However, firmware hanged. I stoped trying to fix it.
As far as I know current App timer uses RTC1 too. Can you link me to an example using of different version of timer?

Hi,

Yes you are not able to step application and work with breakpoints. I apologize but I do not remember details regarding root cause. I kow it was related to the fact that App Timer v2 is using RTC instead of casual timer. When application hits a breakpoint there is some problem with synchronization.

App Timer v1 sources are still available within SDK15. I think you need to only change source file of app timer in your project.

Thank you jakub, I will try this example on. About debugging, do you mean jtag step by step code execution and breakpoints? Can you link me to description what exect behaviour during debugging with app timer 2?to cange to app timer 1 I need just to set define or port piece of code fromprevious sdk version?

Hi,

Please check peripheral CLI example. It has configured 3 backends at the same time: uart, USB and RTT. You will be able to use console and log over RTT.

There is problem with debugging (stepping/traps) due to used version of app timer (v2).

If you would like to use traps and stepping you need to change app timer to version 1.
