I am using GPS Neo6M V2 module with Arduino Mega. I have done this several times in past 5-6 years and not new to this.
However for a latest project I bought 3 new GPS modules and none of them seem to get a fix on satellites. Neither the led blinks at all nor does I get output using Fullexample code of Tinygps++ library. However they are sending NMEA sentences which I verifies using Serialpasstrough example. When I connect old GPS it works even now.
So what I have done is that using Serial pass through sketch I captured the NMEA output of the new GPS module with and without antenna. I am also attaching screenshot of the output I received using "Full Example" of tinygps++ library.
Can anyone suggest what is going wrong? Are the new modules junk?
Serial Pass through output WITH ANTENNA
Serial Pass through output WITHOUT ANTENNA
Full Example code output of Tinygps++ library.
Thanks in advance
