And this is how i connected GPS
Hello,
So it seems that the GPS engine was successfully started and there is some NMEA data.
However the fix is not possible. As I see you have connected the GPS antenna to the wrong connector on the evaluation board - it should not be the middle connector but the upper left one. Additionally I'd recommend you to use some external GPS antenna instead of the one built in the starter kit - because it ***** to be located outside the building to receive the satellites signals properly.
Best regards,
Bartłomiej
Hello,
I got reasonable results with the evaluation board passive antenna. In that test I didn't use assisted GPS,just the basic one, see
EHS8testresults.pdf. Here is a link to a conversation of the EHS8 GPS usage:

The evaluation board was just behind my window.

Hi,
Another GPS example of a PH8 Rel3 with assisted GPS/Glonass and the antenna is inside the room by the window

Dear Antero,
Thanks for quick replay.
But how is the connection from GPS to the extern Antenna using the connectors
Dear Peter,
enclosed you will find a picture of how to connect an external antenna to the evaluation kit.
You can use a U.FL to SMA pigtail cable for the connection.
In my example I have a combination antenna GPS/GSM/WiFi, with only GPS connected.
