How to enable GPGLL on Teseo-Liv3F module ?

[YJain.1]

I am working with Teseo-Liv3F to test NMEA0183 strings over BLSP UART 12 on my board.

1. wanted to know how reset and wakeup are used to monitor UART transfers ?
2. How can we enable GPGLL, GPVTG on the module to obtain NMEA strings?

To test the antenna used is : FR-01-S4-224 ,also gpsmon application and gpsd daemon .

I am unable to get location fixed , only empty strings are coming.

Is there any info about ways to check firmware file is updated, or to flash the binary on the Teseo-Liv3F module ?

Thanks in advance.

Hi

> Is there a Linux variant of the Teseo-Suite application ??

No . there isn't any Linux variant.

In any case the standard NMEA message (GPGGA... GPGLL etc... ) should be parsed by gpsd standard linux program.

> Since in my case the UART port from module is linked to processor without having output FTDI onnection.

both the board EVB-LIV3F and X-Nucleo-GNSS1A1 provide I2C port access to the LIV.

On the I2C port LIV3F proves the same NMEA stream available on the UART.

Hope this helps

Yes, I opt to test it over UART and the log file from Teseo-Suite is :

In the NMEA decoding window:

On sending $PSTMGETPAR

The system didnt print any logs

Is there anything basic I'm might be missing ?

Hi

Sorry but you have to configure and enable the 'Ctrl port'

You can follow the presentation @ https://www.st.com/resource/en/product_presentation/evb-liv3f-presentation.pdf

Hi,

I have got the UART port working, it was issue with the PIN assignment.

I am finally getting UART prints from : tio /dev/ttyMSM3

Is there any existing application/method to parse the values coming from UART, so that I could print Latitude & Longitude values from the GPGLL/GPGSA values printed constantly.

Hi

ST doesn't provide any Linux application.

But on internet there is available GPSD program which could fit your needs: https://gpsd.gitlab.io/gpsd/index.html

Hi @Francesco Virlinzi​ 

I am testing with gpsmon application, getting wrong latitude and longitude values(tried almost for 20mins). Is any tuning/calibration required for this GPS module? If tuning required please let us know the procedure to do the same.

Thanks,

Yash

Hi

Looking the $GPGLL message... in this message the position is reported... all the fields are zeroed.

The module is not evaluating any Position.

More probably you have some problem with antenna.

I assume you are testing outdoor. Is it?

Thanks

Ciao
