Hi,

In gps sample, the prj.conf file is:

 And I can use Putty or Serial.app (on my Mac) to view the output 

In our application the prj.conf file is the following:

NOTE: I haven't written the original code, just took over and continuing developing on it. 

I have tred to set all the settings from the GPS Sample code in our prj.conf-file ... cleaned the solution, closed & re-opened the solution ... to make sure the prj.conf is "applied" in SEGGER ... and freshly re-built the code ... 

But It doesn't seem to work. 

I'm guessing there's a one / few settings that maybe are overriding each other? (if you enable option-x, then option-s won't work ... etc etc) 

Does someone have a clue to what's going on?

----------------

PS - Yes, if I enable RTT in our prj.conf it works ... but I'd like to use serial-console-logging.
