Hey, guys!

Just wanted to share with you that I was finally able to merge libuarte example into the application that contains SoftDevice and app_timer.

Given that fact that SoftDevice requires RTC0 and Timer0 and app_timer library consumes RTC1, I used RTC2 and Timer2 for libuarte implementation:

NRF_LIBUARTE_ASYNC_DEFINE(libuarte, 0, 2, 2, NRF_LIBUARTE_PERIPHERAL_NOT_USED, 255, 3);

The numbers 2, 2 in the above line of code mean RTC2 and Timer2 are taken for libuarte. At the same time, you should have enabled those ressources (RTC2, Timer2) through the sdk_config.h file.

Also, I removed everything related to UART from sdk_config.h file and included drivers from libuarte example:

Finally,

      <file file_name="../../../../../../components/drivers_nrf/nrf_soc_nosd/nrf_nvic.c" />
      <file file_name="../../../../../../components/drivers_nrf/nrf_soc_nosd/nrf_soc.c" />

lines should be replaced with:

      <file file_name="../../../../../../components/softdevice/common/nrf_sdh.c" />
      <file file_name="../../../../../../components/softdevice/common/nrf_sdh_soc.c" />

I did not touch NRFX_PRS_BOX_4 from sdk_config.h file even if it was suggested in this thread.

Cheers!

Bojan.
