Jan Brudny	967e057906	esp-tls, esp_http_client and esp_http_server: update copyright notice	2021-05-31 20:06:09 +08:00
David Cermak	4375f888fa	esp-tls: Fix wolfssl error codes for WANT_READ/WANT_WRITE ... wolfSSL error codes are mostly positive numbers, but esp-tls potentially non-block API (read/write) returns ssize_t, i.e. bytes read/written if >0, errorcode otherwise. To comply with this API we have to conditionate the wolfssl return codes to negative numbers, preferably the same codes as mbedTLS codes.	2021-02-16 09:01:35 +01:00
David Cermak	6b318fe583	esp_tls: Updated connection method to use non-blocking connect ... For better control over connection timeouts To be in line with former tcp_transport, as esp-tls is not used for plain tcp transports	2021-02-16 09:00:43 +01:00
David Cermak	391d7bf271	tcp_transport: Add TCP transport connection errors ... Transport's error_handle is used to capture different types of errors including esp_err_t from esp-tls and socket/system errors. This change adds the following error codes for TCP transport: * connection closed by a FIN flag (clean closure from server) * DNS resolution problem * connection timeout These errors are already defined in esp-tls component and since this component will be used in the future for both TCP and SSL transport, we currently report these issues in transport::error_handle::esp_tls_last_error of standard esp error type (esp_err_t) Closes https://github.com/espressif/esp-mqtt/issues/182	2021-02-16 09:00:43 +01:00
