I am currently experimenting with a RTUX11 and a GPS Receiver capable of RTK correction. I configured Teltonika NTRIP Package to forward NTRIP data via usb connection to my receiver. Via ssh and cat command I can see that receiver answers with rtk fixed position data. How can I forward that to other devices connected via ethernet to my rutx11? There is a serial over ip function, but the receiver is exclusively locked by NTRIP package. Do I have another option to enable both? Sending NTRIP data to receiver and receiving NMEA data back?
The NTRIP client package on RUTX11 takes exclusive control of the USB serial interface connected to the RTK receiver, which means you cannot directly use the built-in serial-over-IP function on that same USB port simultaneously. This is a known limitation because the NTRIP package acts as the client streaming correction data to the receiver and locks that serial device.
To send NTRIP correction data to the receiver and receive NMEA data back simultaneously, you need either:
A second serial interface on the receiver for NMEA output, connected to the router and forwarded via serial-over-IP or TCP/UDP, or
Custom software on the router to duplicate and forward serial data if the port can be accessed concurrently.
There is no built-in option to both run the NTRIP client and forward the same USB serial port data simultaneously on RUTX11 without additional hardware or interface separation.
If your receiver supports outputting NMEA data on a separate interface (e.g., Ethernet, Bluetooth, or a second serial port), using that for forwarding NMEA data over Ethernet is the most straightforward solution.
