nRF9160 DK GPS connection problem

[Bergmann]

Hi, I have a nRF9160 and I am currently working with the gps example: ncs\nrf\samples\nrf9160\gps

When I run the example, I only see 

all the time. I went out on a big field under a cloudy sky and let it run there for 5 minutes several times. Somethimes the Tracking: 0 changes to Tracking: 1, but only for a few seconds, than it changes back to 0.

Do you have any ideas how I can get data in, do I maybe have to use an external antenna? 

Thanks for your answers!

Hi,

 

What version of the nRF9160-DK do you have? Version 0.8.2 and order has a non-optimal GPS antenna match, unfortunately:

On these older DK versions, an external antenna is recommended.

It can take several minutes to get a GPS fix, especially if the sky is cloudy.

 

Kind regards,

Håkon

Hi, sorry for the delay.

I have the 0.8.2 version with the 1.1.0 Modem Firmware, that explains, why it doesn't work. So I will get a GPS antenna.

Should the example work on the Thingy91 or does the Thingy91 also need an external antenna?

Thanks for your help!

I tried it now again with the Thingy91 and it worked, I get now correct GPS Data.

Thanks for your help!
