Esp8266 does not appear to support This is deprecated AxTLS API causing compile warnings

the warnings are know, the problem is that there is no direct replacement for them in the new BearSSL the ESP8266 is using.

the only way to remove the warnings is to remove the functions which will break existing code, for the reason I have not "fixed" them yet. currently I only plan to remove them when there are clear indication that the functions are removed on the ESP.

Thanks for your reply! Hope to repair the warning part as soon as possible! A new version!

@Links2004 Hi this is an heads up : due to recent Remove stray axtls refs, deprecated compat funcs https://github.com/esp8266/Arduino/commit/85ba53a24994db5ec2aff3b7adfa05330a637413

arduino Websocket library is no more compilling, axtls API is not only deprecated but now API is also removed

C:\Users\luc\Documents\Arduino\libraries\arduinoWebSockets-2.2.0\src\WebSocketsClient.cpp: In member function 'void WebSocketsClient::loop()':
C:\Users\luc\Documents\Arduino\libraries\arduinoWebSockets-2.2.0\src\WebSocketsClient.cpp:173:30: error: 'class BearSSL::WiFiClientSecure' has no member named 'setCACert'

So the coming 3.0 core break backward compatibility with axtls API

[Links2004]

ok, thanks for the info. will change the code, hope I find a way to auto detect the new version to not break backward compatibility for 2.x

I do not know if it can help but there are : in core _version.h of 2.7.4

#define ARDUINO_ESP8266_GIT_VER 0x2843a5ac
#define ARDUINO_ESP8266_GIT_DESC 2.7.3-3-g2843a5ac
#define ARDUINO_ESP8266_RELEASE_2_7_4
#define ARDUINO_ESP8266_RELEASE "2_7_4"

when in git version

#ifndef ARDUINO_ESP8266_GIT_VER
#define ARDUINO_ESP8266_GIT_VER 0x00000000
#endif

#ifndef ARDUINO_ESP8266_GIT_DESC
#define ARDUINO_ESP8266_GIT_DESC unspecified
#endif

thanks,

currently I am using:

#if defined(wificlientbearssl_h) && !defined(USING_AXTLS) && !defined(wificlientsecure_h)
#define SSL_BARESSL
#else
#define SSL_AXTLS
#endif

new version 2.3.0 will be released soon, git master is uptodate. feel free to reopen, if problem still exists.

[luc-github]

I confirm compilation is ok too - Thank you so much for this impressively fast response ^_^
