SiPy -> AWS Device Example - CA file not found

[jonnyboy]

Hi,

Im following the official tutorial here:

https://docs.pycom.io/chapter/tutorials/all/aws.html

I have setup the AWS device and downloaded the certificates, then placed them into ther /cert folder but I am getting the error:

Socket create error: CA file not found
Socket send error 128

My certificates have a different naming convention to those in the example.

The example is:

# AWS general configuration
AWS_PORT = 8883
AWS_HOST = 'aws_host_url'
AWS_ROOT_CA = '/flash/cert/aws_root.ca'
AWS_CLIENT_CERT = '/flash/cert/aws_client.cert'
AWS_PRIVATE_KEY = '/flash/cert/aws_private.key'

My certificates are called:

and my code is:

# AWS general configuration
AWS_PORT = 8883
AWS_HOST = 'xxxxxxxx.iot.eu-west-1.amazonaws.com'
AWS_ROOT_CA = '/flash/cert/VeriSign-Class 3-Public-Primary-Certification-Authority-G5.pem'
AWS_CLIENT_CERT = '/flash/cert/b06548fb65-public.pem.key'
AWS_PRIVATE_KEY = '/flash/cert/b06548fb65-private.pem.key'

Please can someone help, i'm out of ideas.

Thanks,

Jon

Can you try formatting the file system and re-uploading the files again, you can do this by running the following from the REPL:

import os
os.mkfs('/flash')

It could be the the file system has become corrupt, it might be worth trying to upload the files via USB if at all possible.

Hi,
Can you confirm that the certificate files were actually pushed to your device? You can do this by running the following in the REPL:

import os
os.listdir("/flash/cert/")
