Provision certificates from the certificates.h is not setting the #define

[hmichel]

I have just switched from SDK version 1.0.0 to SDK 1.1.0 and I am using the MQTT FOTA example

I had the example project working when I was using v1.0.0 of the SDK

I have checked "Provision certificates from the certificates.h file" and clicked the configure button

but in main.c the define at line 28 has not been set so the certificates .h file is not included.

I notice that the name of the define in the menu settings is <PROVISION_CERTIFICATES>

and in the code on line 28 it is CONFIG_PROVISION_CERTIFICATES

Hi.

 

I notice that the name of the define in the menu settings is <PROVISION_CERTIFICATES>

and in the code on line 28 it is CONFIG_PROVISION_CERTIFICATES

 Yes, this is correct. A Kconfig option will generate the #define CONFIG_<name of option>.

 

I have checked "Provision certificates from the certificates.h file" and clicked the configure button

but in main.c the define at line 28 has not been set so the certificates .h file is not included.

 What do you mean by that. Did it not change color?

Did you build the project again after applying the settings?

Or did you empty the build directory?

If you place a #error inside the #ifdef, does it still compile?

Best regards,

Didrik

certificates.h file is It is still grayed out

I did a rebuild (which should do a clean and build) still no change

However, when I put random text inside the ifdef then I get a compile error. 

So it is just a type of display problem and not actually leaving out the certificates.h

Also here is the Terminal trace window from startup. I see the delete inbuilt keys have a result code of zero. Is that ok?

 Yes, that means that it was successfully able to delete the certificates.

When I try to use new certificates from AWS in certificates.h I get a -45 error when I try to connect to AWS. So it seems that the default certificates are not getting overwritten at run time. 

 What sec_tag are you providing to the socket?

And is that sec_tag dependent on some configuration options?

This is what I found for searching the source code for CLOUD_CERT_SEC_TAG

And this is what I found in the nrf Connect Project Settings 

[hmichel]

I have a conditional compile in certificates.h that allows me to pick from 3 different certificate sets that I created for AWS things. If I build the project with the original certificate set of the 3 then the device connects to AWS IoT. But I need to support different certificate sets for each device that will be deployed

So if I understand you correctly, you have a certificates.h file that looks something like this:

// file: certificates.h

#define CERT_A \
"-----BEGIN CERTIFICATE-----\n"\
"aaaaaaaaaaaaaaaaaaaaaaaaaaa\n"\
"-----End CERTIFICATE-----\n"

#define CERT_B \
"-----BEGIN CERTIFICATE-----\n"\
"bbbbbbbbbbbbbbbbbbbbbbbbbbb\n"\
"-----End CERTIFICATE-----\n"

#define CERT_C \
"-----BEGIN CERTIFICATE-----\n"\
"cccccccccccccccccccccccccccc\n"\
"-----End CERTIFICATE-----\n"

#define CERT_TO_BE_USED CERT_A

And then you write CERT_TO_BE_USED to the modem?
