Dear Support, I have GNSS L76-l module and I am trying to see the recommended package with line below
torizon@verdin-imx8mm-07022050:~$ echo -e’$PMTK314,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0*29’ > /dev/ttymxc2
but the response is incorrect, as shown below.
I really appreciate it if you can help me.
Best regards,

Dear Martin,
After you sent the command $PMTK314,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0*29, it’s right to output only RMC sentence. What would you like to output?

Dear Cassiel,
Thank you so much for your reply.
yes, correct I send that command, and as you can see below the time is not correct, I am using the evaluation board for L76-L V2.01

In the output, each second should not be printed accurately.

Best regards,
Martin

Dear Martin,

Reading from from tthe output RMC, why are there a few lines of space? Is this original output from Uart port of EVB? Could you save and send the original logs to me?

Furthermore, Please send commands and send me the response to check its frequency. $PMTK40036 // to query the rate of position fixing activity
$PMTK41433 //to query the current NMEA sentence output frequencies

Cheers
