OpenLog Compatibility with NEO-M9N and Recommended NMEA Log Viewer Software

GPS/GNSS

Hey! Struggling here with a few technical questions regarding the compatibility and data handling of your OpenLog data logger ( https://www.sparkfun.com/sparkfun-openlog.html ) when used with the SparkFun NEO-M9N (One with SMA connector) module. ( https://www.sparkfun.com/sparkfun-gps-breakout-neo-m9n-sma-qwiic.html )
From what I understand, OpenLog is capable of logging NMEA output from the GPS module into .txt files. I would like to confirm the following:

So questions…
Is the OpenLog fully compatible with the NEO-M9N module, especially in terms of logging complete and accurate NMEA data streams?

Do you have any software recommendations for reading and visualizing these NMEA .txt logs?
Ideally, I’m looking for something with a graphical interface that can display satellite signal data, map positioning, and perhaps other telemetry – something functionally similar to u-center, but that can work with .txt NMEA logs instead of .ubx files.
My own searches have not yielded any solid results in terms of suitable NMEA log viewer software. If you have any preferred or internally used tools, I would greatly appreciate your guidance.

Lastly, would it be possible to provide a sample NMEA .txt log file recorded using OpenLog (ideally from a NEO-M9N module)?
This would help me understand the expected formatting and ensure that any third-party tools I test can properly parse the file.

Thank you for attention and help. I highly appreciate that.
If I mentioned something wrong - sorry. I am just enthusiast.

Hi @rz_rz ,

Welcome!

I can’t comment on how well the OpenLog logs a continuous stream of NMEA data. I don’t have one… But that is what it was designed to do, and it has been selling well for years.

PyGPSClient should meet your needs in terms of either displaying and logging live data from the NEO, or replaying a previously logged NMEA TXT file.

I hope this helps,
Paul

Thanks for your message, Paul. I am very grateful for it. At least you mentioned software))) You still helped me a lot! Thanks again!

uCenter should be able to open a .LOG or .TXT file. And a .UBX can contain ASCII text in the form of NMEA Sentences. The extension just allows for the OS to associate an app with the file type.

Thanks a lot. Didn’t had such idea) But checked out with Notepad. True!
