how to set NRF_LOG_STR_FORMATTER_TIMESTAMP_FORMAT_ENABLED active ?

Hi there

I met an error down below.

nrf_log_str_formatter.c(86): error:  #29: expected an expression

if (RF_LOG_STR_FORMATTER_TIMESTAMP_FORMAT_ENABLED)

nrf_log_str_formatter.c: 0 warnings, 1 error

What is the meaning of expected an expression? It is about the sdk_config.h?

Here is the Nordic r eference.

Hi,

 

your if-sentence seem to be incorrect. There should be NRF_LOG_STR_FORMATTER_TIMESTAMP_FORMAT_ENABLED.

If it still gives an error, please check if your sdk_config.h has this defined:

#ifndef NRF_LOG_STR_FORMATTER_TIMESTAMP_FORMAT_ENABLED

#define NRF_LOG_STR_FORMATTER_TIMESTAMP_FORMAT_ENABLED 1

#endif

 

Best regards,

Håkon

Hi sir

Another question.

I replace the Nordic example from ble_app_uart sdk_config.h to  direct_test_mode.

Of course, I also add the header file and enable DTM, but the error occur.

What is the meaning of the undefined symbol?

Hi,

 

You should add the corresponding .c files to your project. You are lacking the SEGGER_RTT files, memobj, atomic, and fprintf libraries. If you look at one of our ble-examples, they shall have all these already added to their project. I'd recommend that you use that one to see which files you'll need to add to your own project. Note that these libraries needs to be enabled in your sdk_config.h.

 

Best regards,

Håkon
