EthernetClient not connecting about esp_sslclient

I test with my W5500 module and ESP32 and it works fine.

There are some user feedbacks about library when using ESP32 with W5500 both works and not work.

Especially when I implement it on my other library that supports external SSLClient and concluded that it may not work in all configurations even using WiFIClient as a client.

The problem is the SSL engine library used in this library for ESP32 is mbedTLS that is already come with core SDK installation.

The mbedTLS works well when binding with lwIP TCP socket directly as in WiFiClientSecure.

The problem is not only at Ethernet module buffer memory restriction but the binding between mbedTLS and Client has some stability and slow data transfer speed issues.

When I test mbedTLS binding with Client (WiFiClient) without socket and Client (WiFiClient) with socket, the result is worst when compare with WiFiClientSecure.

Othe SSLClient libraries that use mbedTLS in the same approach as in this library will not work good in all conditions.

Now I decide to remove mbedTLS as a SSL library and use BearSSL SSL engine library instead as used in ESP8266 core.

From testing ESP32 with BearSSL, it works well as fast connection as in WiFIClientSecure that used mbedTLS.

I and other users also test ESP32 with BearSSL and W5500 and it works fine.

I will finish updating the library soon in this week.

I will post here when the new version is available.

Thank you for the quick response. I tested with just wifi, and that works fine, I know that is using bearSSL. It would be great to try out your new version with bearSSL. Looking forward to it. :)

Forgot to mention one thing. In searching for solutions, I played around with ArduinoBearSSL, and I used Ethernet client to test. It worked by itself. However, when I tried the method in my main ESP32 project, I got so many errors, because ESP32 Arduino already uses bearssl, and may files were already being used, and causing the error of "Already defined here". So, if you were to work with bearssl, It would be great if you can address this as well :)

Now the new version (v2.0.0) is available.

Arduino's Library Manager may be available soon or download zip file to install.

Did a quick test, and it works. Tested with both wificlient and ethernetclient. Both are working. Thanks, I will test further, and update you if there are any issues. Much appreciated :)
