GPS fix error and Initialization String Question

0 votes
Hello, I want to use GPS function on WR41v2, but it's always show no fix or invalid in position page.

I enable local monitoring checkbox and type 'at/gps' command in serial port monitor, but it always show:

$GPRMC,,V,,,,,,,,,,N*53
$GPVTG,,,,,,,,,N*30
$GPGGA,,,,,,0,00,99.99,,,,,,*48
$GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*30
$GPGSV,1,1,00*79
$GPGLL,,,,,,V,N*64

what should I do?

Also, What should I type in the GPS Module Initialization String? Like $GPS_START or something else? Any string list?

Thanks!
