Problem with LC86G for the first position

I am trying to get my GNSS module to work, but I cannot obtain the position within a normal time frame. It takes about 5-6-7 minutes to get the first position, sometimes even longer. This is the firmware version

$PQTMVERNO,LC86GLANR12A02S,2023/12/26,09:53:00*3B.

I can’t find any configuration that would allow it to take an acceptable amount of time to obtain the first position.

Can you share NMEA logs?

Ci sono diverse anomalie, sembra anche uno script eseguito ciclicamente, descrivi meglio l’installazione… comunque:

anche se non dovrebbe essere un comando usato per LC86G

se usa una antenna integrata, meglio una esterna…

meglio metterlo in $PAIR080,0*2E ; Set navigation mode = normal

bypassa tutto e dialoga direttamente con il modulo:
$PAIR003*39  Power off the GNSS system, including DSP, RF, PE and clock
$PAIR512*3C   Clear all data 
$PAIR514*3A  Clear the current configuration and restore the pair settings.
$PAIR023*3B   Reboot 
$PQTMRESTOREPAR*13   Clear all data to default
$PAIR007*3D  Perform a cold start and clear system/user configurations.

Hi Ludovice_Lervolino,

$PQTMANTENNASTATUS,3,1,2,1*52 this message shows the module worked with passive antenna(patch antenna).
Did you test indoors? From $xxGSV message, it showed that module had completely no satellites in view. Please move to an open sky area for GNSS performance evaluation.
For a quick GNSS test, you can do it by the window. But usually the signal level will also be bad.

Best regards.
