NRF_LOG MACROS to SEGGER_RTT?

I think define NRF_LOG_ENABLED and NRF_LOG_BACKEND_SERIAL_USES_RTT in makefile is better way to go as that is indicated from the sdk_config.h. change them directly in sdk_config.h is not recommended.

I could not get this working until i called NRF_LOG_FLUSH() after each call for some reason?

You just need to cast it into uint32_t, nrf_log_push() has different usage. See the documentation

Weird, if I try

NRF_LOG_INFO("Info with integer parameter %d\n\r", 10);

it works, but

NRF_LOG_INFO("Info with string parameter %s\n\r", "some string");

I get:

error: #167: argument of type "char *" is incompatible with parameter of type "uint32_t"

EDIT:

Nevermind, nrf_log_push() seems to take care of that.

yes, NRF_LOG_INFO (and similar) are printf-like.

@Catalin

The nRF5_SDK_12.0.0_12f24da doesn't have the nrf_log.c.

However, it has components/libraries/log/nrf_log.h.

The NRF_LOG_INFO, NRF_LOG_ERROR, NRF_LOG_WARNING, and NRF_LOG_DEBUG is defined in that header file.

Is NRF_LOG_INFO (and the other NRF_LOG____ functions) handling OK "printf-like parameters"? Since from what I can see that no longer seems to work somewhere in the macro expansions and the old NRF_LOG_PRINTF that I was using in SDK11 does no longer seem to be present :(

I no longer see a nrf_log.c in SDK12, where do you have that file?

Yes, nrf_log supports RTT as one of possible backends. In sdk_config.h you can find an option NRF_LOG_BACKEND_SERIAL_USES_RTT that needs to be enabled (NRF_LOG_BACKEND_SERIAL_USES_UART should be unset then).

nrf_log.c allows logging to RTT since it was created (SDK10 i think). In SDK12 just change options in sdk_config.h, in previous versions set NRF_LOG_USES_RTT=1 define and make sure that there are no other NRF_LOG_USES_XXX defines.
