Why NMEA.VI dosent active to extract data form Visa read ?

[Jakkapong]

         Why NMEA.VI dose not  active to extract data form Visa read ?  On the  front panel , GPS data do not  have any information . 

For several day before , I have tried to extract data from GPS sensor ( NEO-6M U-Blox)  as I get the code but it hard to extract the data so 

I choose to use NMEA.VI that it  easy to extract the data from the GPS . 

Sorry for gramma mistake .I hope you understand these above . Thank you advance .

When there is a problem with that NMEA VI, then you should attach that VI, too! (Or atleast tell us, where you got that VI from…)

What's so hard to read/parse GPS messages? They are formatted quite nicely using commas as separators between their datafields! (Think of SpreadsheetStringToArray when talking about "comma separated values"…)

In oyur image the GPGGA message is shown: do you know what data is contained? Certainly there are no longitude/latitide data in a GPGGA message, so your NMEA VI is right when it outputs NaNs instead…

Your doing it wrong... Notice there is no "Bytes at Port" in my VI.

You should watch this: VIWeek 2020/Proper way to communicate over serial

My main GPS vi

Here is how you parse an NMEA "GGA sentence"...

You are just parsing strings at this point...

I have attached a GPS decode project I started a long time ago and never finished. You can use it as a template or finish it as is. I think I had the GSA and GGA sentences completed.

NMEA VI that form Robotic Modules .  

Now , I learn to build the  AGV for pulling 200 kg as I seek the information to compare ROS (Robot Operating System) and Labview Robotic  modules that both  advantage and disadvantage to use in AGV . If you have experience that relate those , Please give me some suggestion . Thank you Sir .

This is a new topic, so start a new one.

[Jakkapong]

OK , I will abide by .

Sorry, I can be a little terse sometimes.  The reason why you'd want to start a new topic is because using the same thread for a new topic will cause confusion, and the fact that the topic already has an accepted solution will cause many members to overlook the topic when browsing the forum.  🙂

Thank for  clarify , I am a new USER sometimes .  If I do wrong , you can expostulate to me . 

Best Regard Jakkapong J.
