CCS/CC3220SF-LAUNCHXL: Issue with MQTT WAS example

I am sorry, there was a type in the title. It is actually MQTT AWS publish_subscribe example in CCS.

Hi Reshmi,

Have you already referred to the the docs within the plugin?

C:\ti\aws_cc3220_1_10_00_07\docs

The bottom of the QuickStart guide goes into the procedure of pulling the certificates from the .pem file into the certs.h file.

It should be similar to the following form in CCS:

const char root_ca_pem[] =
"ABCD1234hxS39SFVT43STY#fdsiEIOFiu2=y!8cZxzXMh+12wDCy21h+8vJsDh4\
<...>
rzcuMZt6oPq6YJMtP3kSaik+bWyzRkdMOPGVL4TiPLAuyAZP1NXl";

hope this helps,

Kevin

I'm seeing similar issues, so have a few questions that might help us understand.

Please confirm the specific certificates to use are:

• CA root certificate string - VeriSign-Class 3-Public-Primary-Certification-Authority-G5.pem
• client certificate string - 7b9e18xxxx-certificate.pem
• client (private) key string - 7b9e18xxxx-private.pem

I believe you should not need to change these unless you use a different thing.

Also, I see in other posts several other suggestions:

• a patch to network_sl.c:  is this required when using the playground certs?

I was trying to print the length of certificates while flashing them using the following code.

Display_printf(AWSIOT_display, 0, 0, "Flashing certificate file ..., len = %d", bufflen);

 

I have observed that the number of characters actually  flashed in each certificate is lesser than the length shown in editor.

For example, for private key the length of certificate flashed is 1588, whereas in notepad++ the length was shown as 1613.

Hi Hendrix,

1)I have confirmed I am using the right certificate files.
2)I changed policy to the below one as suggested in one of the forums.
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"iot:*"
],
"Resource": [
"*"
]
}
]
}

3) Patch to network_sl.c : I got some errors while doing this. Also the code looks like the patch is already there in CCSv7.2.0.
Please confirm if I have to do this.
Also, can you please elaborate on playground certs?

Here is a sample of root CA I have used.
