NEED HELP WITH FOTA VIA DEVICE PROVISIONING ON MY NRF7002DK - AZURE FOTA - IOT HUB

[overflow]

Hello, I'm trying to do the fota via azure IoT hub, except I can't, I don't know if I'm doing it wrong because I followed the doc   Azure FOTA  https://shorturl.at/fsAJ1 ainsi que  Azure IoT Hub https://shorturl.at/eoT57 , maybe I missed something.

sdk 2.5.99-dev1

I would like to add this, when try to download the zephyr.bin on my azure

<err> download_client: Unable to connect, errno 113
[00:00:44.678,955] <err> fota_download: Download client error
[00:00:44.689,544] <err> azure_fota: FOTA download failed

If you need more information, I'm open, thank you, I hope to find a solution :)

Hi,

When you repeatedly edit the ticket, it makes it hard for us to follow the history and development of the issue.

In one of your previous images, it looked like you were able to download the new image. Has that changed, or do I remember the old image incorrectly?

113 is ECONNABORTED, with the explanation "Software caused connection abort". My first guess is that something is wrong with the credentials you have written to the device.

Best regards,

Didrik

Hello, thank you for your follow-up and your advice, I'm sorry for that.

I made a mistake in my analysis, until now I can't download the .bin from my blobstorage.

I'm still exploring different avenues, exactly I've been thinking about the certificate,

I got the error ECONNABORTED 113.
I saw its correspondence in the errno.h "/* Software caused connection abort */",
I modified my CONFIG_AZURE_FOTA_SEC_TAG which was 11, now I set it to 1, because despite the fact that it was 11, in my terminal I saw [00:00:35.305,633] <inf> download_client: Setting up TLS credentials, sec tag count 1.

After setting my CONFIG_AZURE_FOTA_SEC_TAG=1, I get a new error which is:
[ 00:00:35.374,603] <err> download_client: Unable to connect, errno 2.

in the errno.h it's defined as  #define ENOENT 2 /* No such file or directory */

Finally I put back the CONFIG_AZURE_FOTA_SEC_TAG=11 or 10, cause thats what my cert are link to.  I still have the error ECONNABORTED 113. These are the tags I use to communicate with my dps and they work fine, but why don't they work when I want to do the fota? any ideas?

Hi overflow ,  and sorry for the late response.

Can you take a modem trace, so that we can get more details about what goes wrong?

What certificate does the FOTA server use and/or expect?

Best regards,

Didrik

Hi Didrik, just to let you know that overflow seems to be requesting help with an nrf7002DK, not an nRF91 Series DK.
