Freematics ONE+ Model B - No GNSS data

Hi everybody,

just received this little gadget and pushed telelogger firmware in it.
This model comes with built in GNSS antenna.
I correctly configured "config.h" parameters so it connects to APN and sends data to my traccar server.
But... no GPS data!
These are logs:

Never got a message with GPS fix.

Is it normal?
Need an external antenna? I brought this just for the embedded antenna...

Where is the device located? Did you test on your desk?

Used on my desk with USB to check logs.
Then in my car (Toyota Auris) for a couple of days.
No GPS signal at all.
Today i'll receive a OBD2 cable to try put ONE+ in a better position (is under the steering, on the left, now).

Also try using 80Mhz CPU clock.

Ok, 80Mhz did nothing but an OBD extension did the trick. it sits on top of car dashboard with good and fast GPS link.
Now i'm asking something different: is it possible to block data transfer to traccar if GPS cords are 0? Because this gets rid of the routes and speeds calculated by traccar, indicating trips to the gulf of guinea. :lol:
