Hi, There is a base code for HTTPS in the Lwip master code that works with mbedTLS. I have been in contact with Simon regarding this. Simon was very helpful but I was not able to use it. First of all the code is still in development and secondly you need lots of RAM. At some point I think it

Re: [lwip-users] HTTPS support in lwip

Hi Sandeep, Not directly. HTTPS means HTTP+SSL/TLS. SSL/TSL is what bring you the encryption on top of TCP/IP and bellow HTTP. I think this is out of scope of LwIP, the LwIP source does not enable this. But you can use some SSL/TSL library together with lwIP to build HTTPS applications. I have

Thank you very much for your answers. It finally (partly) works now :) I had a priority problem in my freertos which made the lwip init task call too late. I am able to send data outside of the lwip thread now. I am still worried because in my stats I see the following problems/errors: Link Xmit
