Part Number:CC3200MOD
Hello,
We have been created a TLS connection between the CC3200 and an external server using a self-signed root CA (all done through openssl), and it has been working well. We would now like to connect to another server using a certificate signed by AddTrust, but cannot successfully create a connection. We are currently getting error (-155) on connect. The CA we are using is good, as we have successfully connected between a computer and server. The certificate was converted into the '.der' format and uploaded to the CC3200 through CCS Uniflash. All sl_SetSockOpt() options are correct, as they haven't changed from a working state with the self-signed CA. The certificate's Signature Algorithm is sha1WithRSAEncrpytion, whereas our self-signed certificate was using SHA256 algorithm. I have tried all combinations of cipher suites, as well as disabling manual input of cipher suites so the CC3200 may try to find the appropriate method, and all yield error (-155). We are now unsure how to proceed.
Thank you,
Tom
