CAN I USE RTK EXPRESS BASE TO SEND CORRECTIONS TO MI ROVER VIA NTRIP?

Can I somehow cast corrections from my RTK Express in base mode by connecting it through cell phone data to RT2GO?

What I mean is that there is a possibility of communicating via NTRIP my RTK Express base with my RTK Express Plus rover.

Yes, this is a common setup.

See setting the base up as a NTRIP Server: https://docs.sparkfun.com/SparkFun_RTK_ … rip-server

And rover as NTRIP Client: https://docs.sparkfun.com/SparkFun_RTK_ … rip-client

Using your phone in hot spot mode is a quick/easy way to get the base on the internet.
