Hi Raghavn, Could you please confirm that you are cutting and pasting the credential files? The video emphasizes not to use Ctrl+V. Perhaps that corrupts it.

Please let us know if that helps.

Thanks,

Naveen

Team mbed

yes I am not doing CTRL+V , I am using ascii send of the file in minicom(UBUNTU). RIGHT click in Terraterm(WINDOWS) still , I am seeing the same error in both OS.

Please let me know if you have any suggestions for me.

Thanks, Raghavan

Hello Raghavan,

The demo that is included in the STM32L475VG discovery kit is connecting the AWS cloud, provided by ST engineers.

I'm convinced that you'd get successful support within the ST community https://community.st.com/ (login / account required)

The section where you've posted your question is an ARMmbed community.

Kind regards

thanks for the info

Hello Raghavan,

I have a similar problem. Did you solve the situation?

Regards

No, I used one more application, which was for other board, I took help of the author and solved. Just Search Mbed-to-AWS-IoT you will get the fix.
