NEO-M8P-2 GPS RTK RTCM issue

GPS/GNSS Development Boards

I am currently working on Sparkfun GPS-RTK( u-blox neo-m8p-2) module and I am facing some issues.

I have configured 1 module as base as instructed in hook up guide too

  1. Configured the time mode

  2. Base in survey in mode (300,2m)

  3. Enabled all RTCM messages that I need (GPS,Glonass,Beidou)

After doing all this when my survey gets complete with 300s,2m but it still not transmits any RTCM correction that needs to be sent to rover so that it can work in RTK mode. I am still seeing the regular NMEA messages on UART1 and not the RTCM steam.So I need help to find whats the issue?

Thanks

There’s a good example included with the SparkFun Ublox Library (https://github.com/sparkfun/SparkFun_Ub … no_Library). You can grab the library via the Arduino Lib Manager by searching ‘SparkFun Ublox’.

I’m not sure what would be causing the issue. I would recommend using the Ublox software first, and follow their guide (https://cdn.sparkfun.com/assets/6/e/7/1 … 31066_.pdf) as best you can. Once you get it working under U-center, only then would I move on to Arduino (u-center makes it easier to see what’s going on).
