RE: How can I implement logging in mesh light switch example

Hi Jonathan,

When I was running the mesh example some week ago, I managed to print out information, by using printf, to the terminal. In order to get the prints in the terminal it was only required to add some printfs in the code and then run JlinkExe;

Install J-Link Software and Documentation Pack
Open up a terminal
The first board run in terminal
JLinkExe -device NRF52 -speed 4000 -if SWD and after Connect
Open a second terminal and write JLinkRTTClient
As for the second board open up another terminal and write now
JLinkExe -device NRF52 -speed 4000 -if SWD -SelectEmuBySN WRITE-SN-HERE(Can be found on the dev kit) -rtttelnetport 9999 and after Connect
Now open up another terminal and write JLinkRTTClient -rtttelnetport 9999

The explanation to first command is to set up a server where the terminal will listen to and the other one is the client where the prints will appear, so you should get the prints in the JLinkRTTClient if everything works correctly.

Hope it helps!
