January 21, 2019 - 2:15pm, 1849 views

Dear all,

Currently, I am trying to get a board with a PDS8 to work with GPS. First some information:

 
Cinterion
PDS8
REVISION 03.001
A-REVISION 00.000.13

OK 
 
+CCLK: "19/01/21,12:56:27" 

The clock is set to UTC

Settings for the gps:

 AT^SGPSC?
^SGPSC: "Engine","0"
^SGPSC: "Nmea/Output","on"
^SGPSC: "Nmea/Freq","1"
^SGPSC: "Nmea/Data","GGA,GSA,GSV,RMC,VTG"
^SGPSC: "Nmea/Interface","usb5"
^SGPSC: "Power/Antenna","off"
^SGPSC: "****/Antenna","0"
^SGPSC: "Assist/Address","","",""
^SGPSC: "Assist/Data"
^SGPSC: "Assist/Connection" 

When enabling the engine to **** 3, I see the output below,

When using gpsmon, I will not get a fix and after approximately 150 seconds, the engine turns off and I need to reenable it. I did this a couple of *****, but after the same amount of time it will turn off again. All help is appreciated to get the GPS to work.

FYI: the test is conducted outside with a direct line of sight to the sky.

Thank you in advance.
