Connecting nRF9160 to google cloud

[Karma]

Hi, 

I've been trying to connect nRF9160 DK to google cloud by running "google_iot_mqtt" following the directions here https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/how-to-connect-nrf91-to-google-cloud and I'm not sure how to edit the Kconfig file as mentioned in README, would you please show mw a sample of how should the Kconfig file look like.

Hi Karma!

In the blog post all the way at the bottom you can download the project code, which is the code used in the blog post to connect the DK to Google Cloud. The Kconfig file should look like this where you need to insert for instance your Google Cloud project name in the second line.

config GCLOUD_PROJECT_NAME
    string "Name of the Google Cloud project"

config GCLOUD_REGION
    string "Google cloud region"

config GCLOUD_REGISTRY_NAME
    string "Name of the Google Cloud reigstry of the device"

config GCLOUD_DEVICE_NAME
    string "Name of the device in Google Cloud"
    
# Include Zephyr's Kconfig
source "$ZEPHYR_BASE/Kconfig"

Best regards,

Heidi

Do I have to create a google root certificate before generating keys? and if yes how ?

Hi again!

If you read the full blog post, there is a link to Google's root certificate and an explanation on how this works. Root certificates aren't created by the user, but retrieved from the given CA, in this case Google.

Best regards,
