Problems getting the SDK up and running

[jitter]

I just got my nRF9160 DK. Unfortunately the out of the box demo didn't work: 

LTE LC config ...
[00:00:01.029,876] [1;31m<err> net_if.net_if_init: There is no network interface to work with!

However I saw on the forums that this was a known issue in The Netherlands since 2 months ago... iBasis didn't fix this yet?

So my next step was to try to build and flash the firmware. I also ran in to trouble here.
I followed this guide to install the SDK: http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_ins_linux.html#installing-the-required-tools

I checkout out the master branch. Ran `west update`. Then i tried to open a project in Segger Embedded Studio(SES). This is where it fails.

Segger gives me the following error message:

Looks like some configuration mismatch between repositories? So I tried reverting to the latest tag: v0.3.0. However then there is no `west` available. Checking out all repositories manually for that tag. Zephyr doesn't have that same tag.. and I couldn't find versions that work together.

So now I am stuck. Which versions are supposed to work together? Is it even supposed to work? 

I am on macOS 10.14.3

Could you please download nrf connect for desktop & run the nRF Getting Started Guide like described here (Section Getting started with development). In the documentation you provided, there is this note:

"The latest state of development is on the master branch of the fw-nrfconnect-nrf repository. To ensure a usable state, the fw-nrfconnect-nrf repository defines the compatible states of the other repositories. However, this state is not necessarily tested. For a higher degree of quality assurance, check out a tagged release."

The nRF Getting Started Guide installs the v0.3.0 tag of Nordic Connect SDK. Then, you should be able to build via Segger Embedded Studio.

Thank you, I managed to import and compile the project with the following tags:

nrf: v0.3.0

nrfxlib: v0.3.0

zephyr: v1.13.99-ncs2

When I run the asset tracket demo I do not get the error anymore, but the board also does not seem to connect to a network. With the AT firmware the LTE icon just keeps blinking yellow-red(connecting). However the device does find two networks:

- KPN NL

- Vodafone/Libertel

I assume the iBasis SIM is supposed to roam on one of those? Is there anything I can do to force a connection? Otherwise I will just check back later when a new release is available. 

[Bjørn Kvaale]

Yes, the iBasis SIM should connect to one of those two base stations in theory. With the at_client hex file programmed to the board (just program the example via SES, SES will automatically do a sectorerase of the flash), you should be able to connect. You could try watching this video, resetting the board via the RESET button and/or pressing the AT+CFUN? button to speed things up. Also, it may be necessary to press Ctrl + R to refresh the link monitor application if you reset the board.
