I followed the instructions on the section “Connecting the GPS-RTK to a Correction Source”. I got a userid/password from UNAVCO as required. When I press the “Start” button the second box from the left at the top blinks green. The fourth box is a solid green. However, I don’t see anything else happening. I’ve tried various RTCM3 locations, but I get the same results. P807 is my closest server and it is 125 miles from me, if that matters. Is this normal?

Hi, I think it will be easier for the Sparkfun employees to understand and answer if you share your screenshots.
