Nothing changed, compile error. What is wrong? Please, help.
Also i tried attach uart like SDK16 sample, i can't link neaded libraries.

[Edvin]

Hello,

 

Also i tried attach uart like SDK16 sample, i can't link neaded libraries.

 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?

[VyacheslavSS]

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.

[Edvin]

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

[VyacheslavSS]

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.

[VyacheslavSS]

see reply

[VyacheslavSS]

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.
