HTTPS Port 443

[vicatcu]

Hi,

Please can you provide guidance on whether (and how) it is possible to make client application to use an HTTPS-only API with the ESP8266 AT firmware? If not with the AT firmware, can it be done with different firmware?

I tried doing:

AT+CIPSTART="TCP","my_ssl_api.com",443
AT+CIPSEND=126
>GET .... and so forth

But that just gave me back a message from the server saying:

Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

Please can you advise? Thanks!

Hi,

Sorry that Espressif AT bin files do not have SSL (HTTPS) function.

But you could do it by yourself with liblwip_536.a

Here is a sample code of SSL (HTTPS) function http://bbs.espressif.com/viewtopic.php?f=21&t=389

Thanks for your interest in ESP8266 !
