Hello,
I got some issues with the configuration of my F9P receptor. I would like to use it with RTKnavi (http://www.rtklib.com/) with real time processing and I can’t manage. My F9P receptor is connected to a PC by an USB link. I think the problem come to the F9P configuration file / fireware. Have you already encounter this kind of problem ?
Thank you 
Hi there,
Did you try to configure the Receiver Messages on u-center?
Maybe, you must enable the UBX-RXM-RAWX (Multi-GNSS Raw measurement data and UBX-RXM-SFRBX (Subframe Data NG).
u-center > Configuration View > Messages > UBX > RXM (Receiver Manager). Then you may be able to work with RTKNAVI.
Also, you may follow this video to configure your GNSS module (if you are using the NTRIP protocol):
Best Regards,
