I am making an IoT device with the MKR1000.

As a part of the process, I would like to set up an HTTPS connection to https://hit.tl8.co/api/ping (this is a website I have made and control).

The problem is that client.connect(url, 443) is returning false. I have tried normal HTTP and the URL works on a browser. I can also access https://www.google.com. The code is a small variation of the example HTTP client.

As such, I believe that the TLS certificate I am using is not accessible by the MKR1000. Running this report shows that it is a RSA 2048 bits (e 65537) with SHA256withRSA certificate.

Is there a way to get the MKR1000 to accept this certificate? Failing that, what changes do I need to make to this certificate for it to work?

Is there a software solution to get this certificate working?

You need to use connectSSL() instead of connect(), and possibly add your certificate to the MKR1000 as described on Hackster.

  • client is already an WiFiSSLClient object. As such connect() and connectSSL() are the same.

  • I am wondering about the documentation for the library which says: "This class allows to create a client that always connects in SSL to the specified IP address and port" .. also I can't find any specification about what SSL crypto-types will be supported ....
