S212 ANT+ examples Timer problem

Hi,

I tried use app_timer in ant bpwr tx project in SDK15.3. and it worked. Timeout handler was called every time it expired. I checked if there are some differences between config.h files in sdk15.2. and sdk15.3. but they were the same. I also tried download "clear" sdk15.2. again in order to work with not modified sdk and again, app_timer didn't work - timeout handler wasn't called when it expired. In "clear" sdk15.2. I add timer in the same way as it was in sdk15.3. where it worked. So I think there should be some issue in app_timer library when using with s212 v5.0.0.. Please, can you try add simple repeated timer with its handler to ant bpwr tx project in sdk15.2. with s212 v5.0.0. to see, if there is some bug or if I am wrong?

Thanks a lot

Pepam

Likely there may be some missing in sdk_config.h.

Have you tried to for instance open \nRF5_SDK_15.2.0_9412b96\examples\ant\ant_plus\ant_hrm\hrm_tx\main.c and look at how app_timer is included/used there?

Seach for 'm_tick_timer'.

Hi,

yes, i am calling app_timer_create().

I think the problem is in nrf_clock driver, because now it is not enabled in config.h. When I enable it, there is error when building the project. Please see error call.

Are you calling app_timer_init?

Have you verified the calls to app_timer_create and app_timer_start are returning NRF_SUCCESS?
