Hi there!

First of all, thank you for sharing the code! CORs network: Swift Navigation Board: Ardusimple budget (Zed-F9p)

I ran into a issue of not receiving RTCM data from the server when running NTRIP client. I checked that /ntrip_client/nmea is publishing by running the fix2nema.

Any ideas on why? One thing I noticed is the /ntrip_client/nmea isn't consumed by anything

I assume you've figured it out by now, but the ntrip client needs to subscribe to the /ntrip_client/nmea topic in order to get the data to send back to the NTRIP server. That topic is publsished by the fix2nmea node which pulled the data from the ublox node, which received rtcm data from the ntrip client. The connections should look like a loop. The node graph should look something like the below, though probably without the namespace groupings. RTKNodeGraph
