AWS-FOTA Sample

[Karma]

Hi!

I'm trying to use the AWS-FOTA  sample, I flashed the sample onto the board and it connected to the AWS account successfully, but when I try to add the update.bin file to the job document it keeps giving me an error (file exceeds size limit). how can I fix this ?

Hello, 

when I try to add the update.bin file to the job document it keeps giving me an error (file exceeds size limit). how can I fix this ? 

What does the job document say about "size"? Please paste here.

Kind regards,

Hi, 

Sorry, I added the update.bin  to a Bucket and I didn't have any problem with that, but when I try to add it to the job I get this error.

I'm sorry, I was not very specific in my last comment. Following the AWS FOTA documentation, when adding the job file, what size did you specify in this job file/document?

Hello,

I see that you are responding but deleting your reply. Is this intentionally? 

I've tried to replicate your issue but without luck. Since you are getting the error message in AWS, my concern is that you have configured something wrong in the Job Document. What does you job-file look like? It is not the update.bin that should be added to the job document, but a <your text>.json. 

An example of a job file can be found in the documentation of the AWS FOTA library. You can upload it to an S3 bucket on your AWS account and select it from there. If you use the AWS IoT Console, this is the only way to add a job file to a custom job.

As described in our documentation, the .json job file can be uploaded to AWS S3 bucket, and then selected in the job documentation. This is the template:

{
  "operation": "app_fw_update",
  "fwversion": "v1.0.2",
  "size": 181124,
  "location": {
    "protocol": "http:",
    "host": "s3.amazonaws.com",
    "path": "/nordic-firmware-files/0943dfbf-cb10-4eb7-8277-a8b179eaf4ff"
   }
}

From AWS IoT click Manage --> Jobs --> Creat --> Create Custom Job. Now you can add the job-file (<your text>.json):

The sample job-file (above and linked in our documentation) links to firmware.nrfcloud.com (AWS server), meaning you can choose to upload the update.bin to nRFCloud or to AWS S3 Bucket.

This yields two possible locations to download from:

• https://[YOUR-BUCKET].s3.eu-north-1.amazonaws.com/update.bin
• s3.amazonaws.com/.../[YOUR FILE HASH]

Note that using AWS address in <your text>.json should look like:

{
  "operation": "app_fw_update",
  "fwversion": "v1.0.2",
  "size": 181124,
  "location": {
    "protocol": "https:",
    "host": "[YOUR-BUCKET].s3.eu-north-1.amazonaws.com",
    "path": "/update.bin"
   }
}

Let me know how that works for you!

Kind regards,
Øyvind

Thank you so much, I downloaded the file and it worked, but now it is showing that the job is in progress and nothing else
