Gps problem on arduino

Projects General Guidance

Hello. We have project about an GSM Shield. We are tying to send the location of our device using SMS via a GPS through the GSM shield. We don't have any technical problems altough we get an empty message every time we try to get the location from the GPS. We are not sure about which Digital Pin we should connect the GPS through.

Forget all the SMS stuff for a moment.

Do the basic example sketches in you GPS library report a fix ?

The TinyGPSplus library is more up to date than the earlier TinyGPS one.

Don't use delay like You do. Those 1 second delays makes GPS messages get lost.

We did try that It still didn’t worked.

Take another look at reply #2 - there is no point messing with texting until you prove to yourself that the GPS is working.
