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,

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.
