NTRIP Configuration UART2 for WiFi NTRIP Master

Hi,
Sorry in advance for the basic nature of this question.
I have a base and rover with LR radio, and have added the Wifi NTRIP MAster.
I’m just wondering why the CFG-UART2OUTPROT-NMEA is needed to be set to true? the LR is only set to send CFG-UART2OUTPROT-RTCM3X.
Is it a requirement of the NTRIP caster? I’m just wondering, as I’m trying to limit the amount of data being sent and received.
Regards
Denis

Hi,
I configured to send NMEA to rtk2go.com and received the following advice from them.

“ Also, there is no need to send NMEA-183 messages to the Caster, these are in fact wasteful and can affect SNIP’s ability to extract the RTCM3 content that your rover devices want and need. Setup your base to not send these.”

I duly removed the NMEA from the output stream and everything is working well.
As an aside they said the normal frequency for pushing out messages was every 5 or 10 seconds.

I hope it helps.

That’s very good feedback, I suggest that you open an “issue” directly at github: https://github.com/nebkat/esp32-xbee/issues, as the software of the WiFi NTRIP Master is supported by a third party.
Thanks again!

Just to clarify on the info page (https://www.ardusimple.com/product/wifi-ntrip-master/ ) for the product on your site you states “ – P.S: Don’t forget to enable NMEA on UART2 at 115’200bps on your simpleRTK2B.”

I would suggest it should be RTCM3X rather than NMEA.

We changed it to: don’t forget to enable NMEA if you use it as a client, and RTCM if you use it as a sever/caster.

Thank you.
I was probably being pedantic.
Thanks for the update.
