Hi Vyacheslav,

You can find the example code for printing log via UART in mesh my last reply here: https://devzone.nordicsemi.com/f/nordic-q-a/59428/adding-uart-code-to-the-light-switch-server-project
It's made for SDK v4.0 but should be straight forward to port to v4.2

With second question about blochek UART.

I patched SDK16 wiles with:

104:

#ifdef BLOCKED_UART
    uint32_t err_code = nrf_drv_uart_init(&app_uart_inst, &config, 0);
#else
    uint32_t err_code = nrf_drv_uart_init(&app_uart_inst, &config, event_handler);
#endif

because call nrf_drv_uart_init without calback is syncronus. So, after patching uart call in interrupt calls stay OK.

I think it is bug in sdk16, please accept bug report.

Yes, i know what i need. I added more then 10 include and source files. I set ~10 defines. It's really hell task!!! Do you have a working code that output log to uart (or app uart) in mesh examples?

With alternative, i got the soft UART to work! Call in main loop is ok, but in event button_event_handler is blocking!!! I don't undertand why?!

Please, by priority, answer first question.

You need to include the files that it is asking for. Does it work when you do the same with the "new error"?

all examples compiles and working with no changed sources.

But i want see logs via uart in mesh sdk examples.

Please See the first message:

Set option NRF_LOG_ENABLED 1 => error No such file or directory #include "nrf_memobj.h"

CMakeLists was modified by attach needed sources including nrf_strerror.c => new error.

You can reproduce error if try to do that with clear installed sdk.

Hello,

[quote user=""]Also i tried attach uart like SDK16 sample, i can't link neaded libraries.[/quote]

Does that mean that the examples doesn't compile even if you don't modify them?

Let's take one of the errors:

/home/shubin/electronic/firmware/nrf/nRF5_SDK_16.0.0_98a08e2/components/softdevice/common/nrf_sdh_ble.c:133: undefined reference to `nrf_strerror_get'

This is defined in SDK16\components\libraries\strerror\nrf_strerror.c

and it is "protected" by

#if NRF_MODULE_ENABLED(NRF_STRERROR)

which is a macro saying:

#if ((defined(NRF_STRERROR_ENABLED) && (NRF_STRERROR_ENABLED) == 1)

So,

1: Is nrf_strerror.c included in your project?

2: What is NRF_STRERROR_ENABLED in your sdk_config.h file set to?
