# Getting NRF Logging to work in Segger Embedded Studio

Getting NRF logging to work in Segger Embedded Studio

Segger Embedded Studio is a lightweight IDE that is used for Nordic devices. Getting logging to work with the 15.3 SDK has been a long journey though, so I thought I might write down my process in getting the debug terminal to print out RTT messages.

## Ensure flags have been set

Ensure that RTT logging has been enabled in sdk_config.h:

#define NRF_LOG_BACKEND_RTT_ENABLED 1

and

#define NRF_LOG_ENABLED 1

## Use the correct sdk_config.h

For some reason the example code for the TWI scanner did not work for me, and copy-pasting code from TWI sensor for the sdk_config.h file worked. Check by launching Segger RTT viewer. If the flags have been set and the correct config file is used, then you should start to see some output.

## No output on the debug terminal?

Close the RTT viewer since you can only have one RTT viewer open at any point in time.

## New lines printed on the debug terminal but no text?

This is actually a bug with the SDK. Check it out here on the Nordic forums, but essentially you have to set this line to 0 in sdk_config.h

#define NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED 0
