GPS hard error

by Capture Thu Jun 25, 2015 2:52 pm

Hello everybody,
I encounter the following problem after flashing geoloc_fix & geoloc_fix_move examples :

Code: Select all
Movement detected
Starting fixing
[TRAP] Time:0.00:00:17.347 : 25:GPS hard error | Param:0x00000000(0)

Is it a hardware related problem ?

Best regards,

Hi,

You need to set this header in order to power the GPS:

Thanks for the input Loïc.
Problem is partly solved. Everything works with the provided Antenna and another active antenna (Taoglass AP10E). However, we encounter the same error while plugging an FXP.611 from Taoglass. I'm unsure as to why. My guess is that it's because it is passive. Played with the jumper with no luck and din't find any mention of it in the docs. Any idea ?

Best,

Stanislas.

Hi,

Not sure why a passive antenna does not work but anyway you need an active antenna to get proper gps performance.
