* Fix possible infinite loop in the example * Remove workaround of sockets always return -76 Remove workaround of sockets always return -76 (because it's fixed on IDF now) Remove delay during handshake (improving stability) * Remove unusable mbedtls_net of context creation * Fix bad destructor * Compatibility with WiFiClient for HTTPClient * Initial port from ESP8266 Changed SHA1 fingerprint by Root CA verification Changed log system * Remove deprecated function
