Help with ZED-F9P Basestation/Rover Project

GPS/GNSS Development Boards
1

I work in a research lab and bought two ZED-F9P GPS modules (https://www.sparkfun.com/products/15136) and configured them exactly according to this guide (https://www.youtube.com/watch?v=FpkUXmM7mrc). For whatever reason, when I connect the TX port of the basestation to the RX port of the Rover, the Rover does not receive the correction data. I followed the hook-up guide (https://learn.sparkfun.com/tutorials/gp … 1590512638) and ran into similar issues. Any idea on what’s going wrong? Any assistance would be greatly appreciated.

(P.S. I know this isn’t a designated GPS forum (sorry!), but the GPS forum had been locked)

If you can use an oscilloscope to verify that signals are being sent to-and-fro then I might suggest reaching out to Ublox via their forums to see if it’s a software issue. Are you porting the correction data to the correction module via Ucenter?

Did you connect a ground between both boards as well?
