Hi,

This might mean that you need to select sec_tag which is not in your current list. You can also use %CMNG command for credentials storage management if you want to write, read, delete and check for existence of keys and certificates. Information about security tags can be found on the TLS/DTLS webpage.

AT+CEREG command can be useful if you suspect network registration issues. You can find example here. You can also use AT+CSCON for signaling connection status notification.

For setting APN manually, you can use CONFIG_PDN_DEFAULT_APN option. The example is given in optional library configuration of the asset_tracker_v2 sample. You can set the status and enable/disable APN using AT command %XAPNSTATUS.

Dejan

Hi Dejans,

Thank you for the pointers, I've follwed these steps (generated new certificates, created a new thing), but still no aws connection..

"4. Select a security tag that is not yet in use.... "
Q: How can I tell whether a tag is in use or not?

PS C:\nordic\myApps\at_client> nrfcredstore COM46 list
Secure tag Key type SHA
24 ROOT_CA_CERT AE106824...........
42 ROOT_CA_CERT 960D85D6...........
16842753 ROOT_CA_CERT 67AA1646...........
16842753 CLIENT_CERT D3EC5AB1...........
16842753 CLIENT_KEY EB05280A...........

4294967294 DEV_ID_PUB_KEY 908D98D2...........

Yes, I do have an AWS account and many other projects working with it.
Yes, I've added these 4 CONFIG_* lines in proj.conf and it is now compiling.

I think the first problem is that it is not connecting to the cellphone network.
How can I check this (Cellular monitor is not working, because Trace is not enabled).
Where do I setup my APN. Are there other service provider cridentials I need to confirm?

Hi,

Setup section of the AWS IoT sample provides information on how to set up AWS and configure permissions. This is required if you want to use AWS IoT Core. You would also need to set up AWS account. Have you performed all mentioned steps?

[quote user="DonP"]

The very first problem is that I can't even compile aws-iot sample app out the box.
I create a new application - Copy sample - Filter nRF9161 DK Non Secure - AWS IoT Sample -> c:\nordic\myApps\aws_iot
Add Build Configuration - Board Target: nrf9161dk../ns
Add Configuration File - prj.conf
Build Configuration

It compiles with error:
pp.a(main.c.obj): in function `on_aws_iot_evt_connected':
C:/nordic/myApps/aws_iot/src/main.c:200: undefined reference to `boot_write_img_confirmed'

A Solution that helped: community.circuitdojo.com/.../4
CONFIG_FLASH=y
CONFIG_FLASH_MAP=y
CONFIG_STREAM_FLASH=y
CONFIG_IMG_MANAGER=y

[/quote]

Are you able to successfully build your project by adding 4 mentioned Kconfig options to your project configurataion?

Best regards,
Dejan

I followed the basic examples: I can successfully build and update a Blink app.
Also programmed "Serial LTE Modem" app using Quick Start using nRF Connect for Desktop.

I looked at some online info on nRF Connect SDK:
docs.nordicsemi.com/.../index.html
Lessons 1 - 5: academy.nordicsemi.com/.../
www.youtube.com/watch

It compiles with error:
pp.a(main.c.obj): in function `on_aws_iot_evt_connected':
C:/nordic/myApps/aws_iot/src/main.c:200: undefined reference to `boot_write_img_confirmed'

A Solution that helped: community.circuitdojo.com/.../4
CONFIG_FLASH=y
CONFIG_FLASH_MAP=y
CONFIG_STREAM_FLASH=y
CONFIG_IMG_MANAGER=y

I've added certificates to directory: C:\nordic\myApps\aws_iot\certs
and updated prj.conf and main.c as per my previous email.

I've tried to use Certificate Manager, but I'm not sure if that's the right route.

I've also searched and found this info:

Hi Don,

Can you provide information how you added the credential to your nrf9161-dk board? Which guide did you follow?

Best regards,
Dejan
