I performed a reboot of my pc, and I have also changed the location of my build folder (shortening the path to the build folder). I am now able to successfully build both asset_tracker and at_client.

I hope that was it, and that I can continue to build in the future.

Oh no... I am getting new errors when trying to build the at_client sample, see below...

What could be the cause this time?

Hi Amanda,

I am able to build the project now, which is great :)
I did as suggested, and changed the "requirements.txt" file. I was then able to complete the installation with no further issues.

I also didn't have any issues flashing my merged.hex to the DK. However, I don't seem to be able to get a connection. I am running asset_tracker, in an attempt to add the DK to my nRF Cloud, but only LED 3 blinks. Should I open a new thread on this topic?

Nevertheless, thank you for your help :)
Jesper

Hi Jesper,

Please see Bjørn Kvaale's suggestion in this post:

changing hub == 2.0 to git-spindle == 2.0

Hi,

I deleted the nsc folder, and performed the commands as per instructions in Section 2.
I had no issues cloning the nRF Connect SDK, nor any when using a tagged version (v1.0.0).
But when I tried to install the required modules for Zephyr, I get the following error:

Collecting hub==2.0 (from -r zephyr\scripts\requirements.txt (line 10))
  ERROR: Could not find a version that satisfies the requirement hub==2.0 (from -r zephyr\scripts\requirements.txt (line 10)) (from versions: 0.0.1, 0.1.0, 0.1.1, 0.1.2, 0.1.3, 0.1.4, 0.1.5, 0.1.6, 0.2, 0.2.0.1, 0.2.0.3, 0.2.0.4)
ERROR: No matching distribution found for hub==2.0 (from -r zephyr\scripts\requirements.txt (line 10))

When trying to install hub==2.0 manually, I get the same error.
By the looks of it, there seems to be no version "2.0" for hub. The "closest" version is "0.2".
Should I try to install this version (v0.2) manually?

The requirements for "nrf" and "mcuboot" installed with no errors.

Edit: I have not tried the tutorial mentioned. Will do so soon.

Hi,

Could you delete the ncs-folder and follow the instruction of "Getting Started Assistant" Section 2 again?

This tutorial/Asset Tracker Application section also indicates how to build Asset Tracker on the SEGGER Embedded Studio.

Hi,

Yes, I did run "west update".
I just tried to run the commands again, but with no luck. I am still getting the same errors when I build.

Hi,

Just to make sure, did you also run "west update" after changing the tag?

Please run these commands and build the code again.

git checkout v1.0.0
west update
