HTTPS with W5500

Question

Hi, in my project I send data to server using https post method. In my code I use the request.py module found in HTTP_Client example. When I use the https I need to execute the wrap_socket(), but the RP2040 takes a long time to execute it. Is there a way to overcome this problem perhaps by delegating this task to the w5500? Thanks.

Do you know we support the HTTP Client example ? RP2040-HAT-MicroPython/examples/HTTP/HTTP_Client at main · Wiznet/RP2040-HAT-MicroPython · GitHub. This example use the ussl library and wrap_socket() in the urequest.py. In addition, W5500 not support the wrap_socket()

Hi, my code starts from HTTP_Client example, and if proto==‘https’ the code executes (taking a long time) wrap_socket(). If I try to run the wrap_socket() function only the first request, without close the socket, at the second request I get the exception: -28928 Thanks for the help Best regards
