SparkFun RTK Profile Questions

GPS/GNSS Development Boards
1

I have a SparkFun RTK Express running System Firmware: v3.2-Mar 8 2023.

When I scroll through the options by clicking on “setup”, I am presented with the following:

mark

rover

base

bubble

config

e-pair

ap mode (profile)

wifi mode (profile)

Profile3 (profile)

Profile4 (profile)

My first question is what does “e-pair” mean and how is it used?

My second question is how can I delete the entries “Profile3” and “Profile4”? I created four profiles, but now I only need the first two (ap mode and wifi mode). I can reset profile 3 (Profile3) and profile 4 (Profile4), but I canont delete either profile name. When I try to delete the profile name, I am presented with the following error message: “Error: Must be 1 to 49 characters”

Thanks for any guidance on either of these questions.

what does “e-pair” mean and how is it used?

E-Pair is a way to pair two units for RTCM transmission using the internal 2.4GHz radios: https://docs.sparkfun.com/SparkFun_RTK_ … nu_radios/ It’s limited range, but it’s free/built-in hardware.

My second question is how can I delete the entries “Profile3” and “Profile4”?

Use the Profiles Menu: https://docs.sparkfun.com/SparkFun_RTK_ … _profiles/

Do you happen to know what MARK does ?

I dont see any special marks in the SFE_Facet_XXX.ubx files.

That creates a separate file containing the coordinates of the mark that was just created. It’s basically a shortcut to avoiding using GIS software and just ‘go headless’.

The Marks feature is enabled using the serial configuration. Select the “Configure Logging” option and then enable option “7”. See https://docs.sparkfun.com/SparkFun_RTK_ … -interface

When the Marks feature is enabled a file is created on the micro SD card with the file name “Marks_date.csv”, specifically “Marks_year_month_day.csv”. As an example: Marks_2023_10_19.csv. This file contains comma separated data with the first line being the header containing the column names. Each line of data includes:

  • - Year-Month-Day
  • - Hour:Minute:Second
  • - Latitude
  • - Longitude
  • - Altitude in meters
  • - Number of satellites in view
  • - Horizontal position accuracy in meters
  • - Battery level (percentage)
  • - Battery voltage

    • Each time the Mark entry is selected using the “Setup” or “Power” button, a line is written to this file.
