If you follow the RTKLIB tutorial at http://www.emlid.com/navio-rtklib, you need to do some changes in the rover-single.conf file, downloaded from https://github.com/emlid/RTKLIB/archive/master.zip
inpstr1-type =spi
should be
inpstr1-type =tcpcli
and
inpstr1-path =/dev/spidev0.0
should be
inpstr1-path =127.0.0.1:5000
The tutorial claims that these changes has already been made in the rover-single.conf file, but it has not.
Thanks!
