Hi, I received a new GPS NEO M9N with an ANN MB 00 00 antenna.

when powerin it, the pps led turns on once at the start and then does not flash again

I connect de GPS module via I2C to a SamD21 mini breakout. Connection is ok. I use ‘basic nmea read’ example.

I tried the 'reset to factory default example without changes.

the output is as this:

$GNRMC,V,N,V*37

$GNVTG,N*2E

$GNGGA,0,00,99.99,*56

$GNGSA,A,1,99.99,99.99,99.99,1*33

$GNGSA,A,1,99.99,99.99,99.99,2*30

$GNGSA,A,1,99.99,99.99,99.99,3*31

$GNGSA,A,1,99.99,99.99,99.99,4*36

Have you tried testing the GPS outdoors under an open sky?

Yes, of course, I forgot to mention this. Tests were performed outdoors, under clear sky. The GPS was there for half an hour at least

It’s either a bad antenna or a bad GPS. If you have another GPS antenna, give that a try and see if you’re able to eliminate the receiver as the faulty component. You might need to return both to sparkfun for them to test.
