Hello. I have a problem getting a position via GPS. My dev board is placed in a good place, but can't get a position after more than 1 hour.
I am using you new SW version v1.0, and HW version 0.8.5 with firmware version 1.0.
The GPS example code works, sometimes I get a position after 1 hour.
Hi Miro,
From the GPS documentation:
From the GPS Tutorial:
"It can also be very practical to attach an external GPS antenna when doing development and test indoors. That allows you to put the GPS antenna near a window in order to see satellites."
Hello Martin. Yes i know it. I have a board on the window. On the same position different GPS module is work
Hi Martin.
Yes, I'm use same Molex helix GNNS antena. With external antena I have same problem
Hello Martin.
- Yes, switch position is on the internal antenna, and i'm use internal antenna. I'm use same antenna with U-Blox ZOE GNSS module, without GPS amplifier, and all is works.
This is my console output

Hi Miro,
Please try to use the "Molex helix GNNS antenna" connected to the nRF9160DK and set the switch to the correct position.
(so not the internal antenna)
I'm use my external "Helix GNSS antenna", and I had a fixed position after ~20min minutes. With internal antenna I had a fixed position after ~2-3hour. And with external big RHCP antenna, I had fix GPS position after several minutes.
But I have on the same position other GPS module with my external Helix antenna, he has a fixed position in a few minutes.
You prototype board have problem with HW ? Or this is SW problem ?
