HHTP client with TLS

Question

Hi all, this is my first post to the forum. I want to send GET or POST requests to servers which require a HTTPS connection. This is probably a common requirement but I haven’t been able to find relevant older threads on the forum. I am using a W5500 chip driven by a STM32F446 microcontroller I was able to compile and run the Wiznet examples on Github for an HTTP client: https://github.com/WIZnet-ioLibrary/W5x00-HTTPClient and also for secure TLS connection https://github.com/WIZnet-ioLibrary/W5x00-TLS However I am really struggling to understand how to merge the two concepts together and I need some pointers or better an example to get me started. Any suggestions would be appreciated. Thanks Riccardo

Hi. You can find the functions of a name that begins with wiz_tls_xxxx. like wiz_tls_connect(), wiz_tls_read(), wiz_tls_write()… You should use those functions on the httpClient.c file instead of using previous functions like connect(), send(), recv()… I hope you succeed. Thanks.

Has anyone been able to get the W5500 to connect to https? Even if the certificate is invalid, that would be OK. Are there any examples?

Hello, I’m trying since few days to run the example W5x00-TLS from Wiznet but the handshake stays blocked at the step MBEDTLS_SSL_SERVER_HELLO. My board is a Nucleo-L152RE Looking for some help on the forum, I have seen that you successed to run this example. What kind of fix have you done to run the example on your board ? Regards Maxime
