Hi,
I’ve just purchased my LS20031 GPS received, but can’t get a lock on sat’s. 
The LED pulses once at power on then remains unlit. I’ve given this several minutes in open sky and still nothing.
The NMEA sequences are being transmitted at 57600 baud, but also indicate no lock…
$GPGGA,190355.159,0,0,M,M,*4E
$GPGLL,190355.159,V,N*7C
$GPGSA,A,1,*1E
$GPGSV,1,1,01,22,37*7C
$GPRMC,190355.159,V,0.00,0.00,100811,N*42
$GPVTG,0.00,T,M,0.00,N,0.00,K,N*32
I believe this indicates no lock and no sat’s - right?
Help !
Steve.
