I can only read ""Still Waiting: No Valid Fix"" from the serial monitor.
What are the reasons for this problem?
I tried retrieving the GPS data outdoors but also failed.
Btw, i tried using the RAW_GPS_TESTER and it works.
I am able to read data like A0,A2,0,5B,29, .... ,B0,B3.
But when I moved on to EM406_Tester,
I could not read any data from the serial monitor except "Still Waiting: No Valid Fix"
Any one knows what might be the cause?

Are these values read from the serial monitor correct?
Are these values accurate?
If the alt is altitude, why does the values changes so much?
and I am somewhere level 6, which means cannot be 70metres above the ground.
How does GPS read ground speed?
Is your GPS module's red LED on?
