AWS FOTA fails when using my upload.bin file for nrf9160

[hmichel]

Previously I have been successful getting the AWS FOTA update working using the AWS FOTA example project, the example update.bin file and location provided

by Nordic for the nrf9160. I did have excellent help from Nordic to get that working.

Now I have created my own update.bin from the AWS FOTA project

1) Create update.bin by making a build (get its exact file size from Windows Explorer)

2) Create an s3 bucket for the update.bin file (it has logging turned on)

3) Create another s3 bucket for the logging of events from the bucket with update.bin

4) Upload the update.bin file to the s3 bucket

5) Create a json file to point to the update.bin file

6) Upload code to nrf9160 using Segger

7) Wait for LTE connect complete and board ready for update by observing Termite terminal 

8) Create a job to perform FOTA update using the update.bin file

9) Get MQTT disconnect error

here are related screen shots

Hello,

First of all, what version of NCS are you running and what is current modem FW?

I see that you have configured your job file for an HTTPS address. Have you configured this accordingly as described in the download client? In the original job file example shown in AWS FOTA library, the address points to a nRFCloud address using HTTP.

Error message -57 is defined as follows:

ENOTCONN 57     /* Socket is not connected */

Kind regards,

Øyvind

Dear Øyvind

The NCS version is 1.0.0

The Modem Firmware is 1.0.0

Another thing to test before my last comment:
In the AWS FOTA sample documentation, under Prerequisites, you are instructed to add a permissive policy for testing only. Could you try to add a new Policy with the following:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::your_S3_bucket/*"
        }
    ]
} 

I found this in the AWS documentaion.

Here is my new policy

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::mynrf9160fwupdatev1/*"
    }
  ]
}

But now the code on the board does not proceed far

enough to indicate that it is ready for the FOTA update

But my original policy

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "iot:*",
      "Resource": "*"
    }
  ]
}

At least allows the code to get ready for the FOTA update

I tried this policy instead and it got me back to where I was 2 days ago. The FOTA update will

start but then get stuck in progress

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::mynrf9160fwupdatev1/*"
    },
    {
      "Effect": "Allow",
      "Action": "iot:*",
      "Resource": "*"
    }
  ]
}

Thanks for testing this at least.

Then the issue is clearly with the Download Client and the HTTPS settings that you need to configure.  I'm sorry for the inconvenience, but I hope this will solve the issue. And for what it's worth, this is a huge help for us to improve our documentation.

Thank you for all the effort. I am happy to help with your documentation process.
