GNSS on EC25E EVB not throwing position data(NMEA)

Hi,

Thanks!

I am working on GNSS over EC25E EVB interfaced with i.MX8. I could enable GNSS via AT command & see the logs, but all the time GPGGA values are empty only. Below given are the logs:

$GPGGA,0,66
$GPRMC,V,N53
$GPGSV,1,1,02,06,14,17,45,009,2642
$GPVTG,T,M,N,K,N2C
$GPGSA,A,1,1E
$GPGGA,0,66
$GPRMC,V,N53
$GPGSV,1,1,02,06,14,17,45,009,2743
$GPVTG,T,M,N,K,N2C
$GPGSA,A,1,1E
$GPGGA,0,66
$GPRMC,V,N53
$GPGSV,1,1,02,06,14,17,45,009,2541
$GPVTG,T,M,N,K,N2C
$GPGSA,A,1,1E
$GPGGA,0,66
$GPRMC,V,N53
$GPGSV,1,1,02,06,14,17,45,009,2642
$GPVTG,T,M,N,K,N*2C
$GPGSA,A,1,*1E
$GPGGA,0,*66

I changed position of antenna multiple time but same result. Used "AT+QGPSLOC"command to get current location but its showing CME error 516. Can you suggest any input on this?

Dear Sir

From the GSV statement, there are too few search satellites. It is recommended to test it in an open sky environment.

Best Regards

Hi Chen,

Thanks!

I will re-position Antenna properly.
