Turns out i did not quite initialize nrf log quite well in the other project. For nrf log to work properly the main function must contain the following codes:

 APP_ERROR_CHECK(NRF_LOG_INIT(NULL));
 NRF_LOG_DEFAULT_BACKENDS_INIT();
     NRF_LOG_INFO("Blah\r\n");
     NRF_LOG_FLUSH();

This project you recommend works! Now I need to figure out what made the other project not working.

Thank you very much!

To begin with, could you try the following:

Open C:\Nordic\nRF5_SDK\nRF5_SDK_16.0.0_98a08e2\examples\peripheral\temperature\pca10056\blank\ses\temperature_pca10056.emProject
Replace C:\Nordic\nRF5_SDK\nRF5_SDK_16.0.0_98a08e2\examples\peripheral\temperature\pca10056\blank\config\sdk_config.h with the following file:devzone.nordicsemi.com/.../sdk_5F00_config.h
Connect your nRF52840 DK (pca10056) to your computer and turn it on
Open a debugger session in SES
- Debug-->Go
Check if you see the RTT logging in the Debug Terminal:

Best regards,
