My SES was too old.

Thank you!

All is well

We have had issues wrt. ordering of compiled object in SES versions (v4.16 and v4.18), so in these versions you might have to recompile.

Could you try the latest SES version and see if this works better?

Thank you. your suggestion worked.

I had issues with 'west update' which were resolved.

I had to switch to an older version of GNU (x-2018-qx to 7-2018-q2-update) according to getting started assistant. After I did that 'west update' worked fine.

I do have another issue i have to fix now if you have any suggestions or should I open up another ticket?

When I build any sample:

No such file or directory: 'C:/nRFsdk/ncs/nrf/samples/nrf9160/at_client/build/zephyr/CMakeFiles/offsets.dir/arch/arm/core/offsets/offsets.c.obj'

Hi,

[quote user=""]1. I have uploaded 'asset_tracker' onto my PCB and I get error -111. I think this is due to certifications required to connect to nrf cloud. Please confirm or correct me.[/quote]

This is correct. Only development kits have nrf cloud certifications preloaded onto the nRF9160.

[quote user=""]2. I tried using 'mqtt_simple' but compiler cannot find reference to 'net_addr_ntop(family, src, dst, size);' in 'socket.h'. How can I fix this issue?[/quote]

It sounds like the "nrf" revision is not compatible with the other repositories it depends on. When updating "nrf", you also need to run "west update":

cd ncs/nrf

west update

Could you try this, then rebuild the sample?

Kind regards,

Håkon
