Hi,
I am trying to get a GPS reading on the NRF9160DK. I have tried both the GPS sample (no SUPL client) and the A-GPS sample, but with neither sample projects I manage to get a GPS fix.
Information:
- NCS: v1.7.1
- MFW: mfw_nrf9160_1.3.1
- Sim card: iBasis
- DK version: 1.0.0
- Location: Noord-Brabant, The Netherlands
I have tried the following:
- GPS sample: Both indoors and outdoors in open sky (very cloudy weather), tried both with external antenna enabled and disabled. All test gave the same output.
Output:

- AGPS sample: Both indoors and outdoors in open sky (very cloudy weather). Both test gave the same result.
