We have just added support for SES. Hopefully a CMSIS Configuration Wizard will be built into SES by default in the future.

Thanks! how could I have missed that.

But why is this step not included by default?

Also maybe you might know what NRF_LOG_FLUSH(); function does that's what it says in the info center page: "Macro for processing all log entries from the buffer. It blocks until all buffered entries are processed by the backend."

That step is explained in the video SEGGER Embedded Studio - CMSIS Configuration Wizard: www.youtube.com/watch

Ah yeah thanks but there is a step in the video I can't preform sins when I right click sdk_config.h it wont show me the CMSIS configuration wizard option in minute 2:45 of the video.

Now the question is where can you see them?

With SES you can see the RTT messages in the built-in debug terminal:

With the examples in the SDK, make sure that you in sdk_config.h have NRF_LOG_BACKEND_RTT_ENABLED and NRF_LOG_ENABLED set 1.

All this is covered in our Youtube video "SEGGER Embedded Studio - Basics of debugging", it can be found here: www.youtube.com/watch

Segger RTT gets the data from SWD. The chapter on RTT in the JLink user guide provides more detailed API info on RTT usage: ~\SEGGER\JLink_V612e\Doc\Manuals\UM*_JLink.pdf

So I understand that inorder to read the data coming from this function you have to connect an external device? what is RTT? can it cast data like this from the SWD port?

about the inforcer I see there is some info about functions I wanted to read about which is nice.

Now just waiting for an answer about the other library question

Thanks!

I suspect the nrf_log_info() dumps the data to the uart (Nordic folks can correct me if I'm wrong here). You may also consider using the segger RTT in case the uart is already used to connect to another peripheral (eg. a GSM module).

The infocenter has the API description for various SDKs: infocenter.nordicsemi.com/index.jsp
