Hi,

The errno you are seeing is this one: https://github.com/eblot/newlib/blob/master/newlib/libc/include/sys/errno.h#L147

This is normally because certificates were not properly provisioned, or in some cases; the SIM card is out of data.

Did you provision certificates, as described under "Provision certificates" in the linked blog post?

Kind regards,

Håkon

My device IMEI is: 352656100782559

I generate certificates with custom:
Device ID:352656100782559
PIN/HWID: 123456
I prj.conf is configured as: CONFIG_COMPILER_OPT"-DNRF_CLOUD_CLIENT_ID""352656100782559"

My test results are:
As follows

The resulting certificates are as follows:

How to connect to nrfcloud with your own modules

Hi,

Only Thingy:91 and nRF9160-DKs have preloaded certificates matching the IMEI, and a HWID/pin.

However; you can generate your own certificates, just not name them with "nrf-"prefix.

If you follow this guide, then generate a new certificate which isn't named nrf-*:

https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/nrf-cloud-certificate-update

Follow the guide as you would if it were a nRF9160-DK or a thingy, just that you have given it a new name and pin number.

The "pin/hwid" field can also be freely chosen, just remember it for when you should add the device to your cloud account.

Before compiling the asset_tracker sample, you define "NRF_CLOUD_CLIENT_ID" to match your newly generated certificate name and compile/flash the project to your device.

If you want to add this define directly to your prj.conf, it would look like this (note the string starts and ends with \" and \" symbols):

CONFIG_COMPILER_OPT="-DNRF_CLOUD_CLIENT_ID=\"my-new-nrf9160-cloud-certificate-name\""

Kind regards,

Håkon
