RTT viewer not always showing all hex strings

[Wim]

RTT is a very strange beast. It looks that, depending the printed binary content, the output in the viewer can be displayed - or not. It seems that the rtt viewer acts on some byte sequences. I attached 2 pictures.

Picture 1 seems to print nothing after "Net TX:"

But there is invisible content, you can select it with the mouse; and it highlights in blue.

This problem can pop-up everywhere - it just depends on hex strings.

Hello,

This is probably not related to the nRF, but rather Segger's RTT Viewer?

It may be that for some reason, you are logging with text color (=black)? Is that the case?

In your sdk_config.h file, what is NRF_LOG_USES_COLORS defined as? 

Have you tried using Segger Embedded Studio, and monitor the log there? Does the lines sometime disappear there as well?

Hi Edvin,

you are right, it is the viewer itself. I set up JLinkExe / JLinkRTTClient (telnet) which works perfectly.

Thanks,

Wim
