esp_transport_ws_set_config() function

websocket transport handle

pointer to websocket config structure

Get user data context of this transport

Transport read function @note: Please refer to the enum `esp_tcp_transport_err_t` for all the possible return values

Returns esp_tls error handle. Warning: The returned pointer is valid only as long as esp_transport_handle_t exists. Once transport handle gets destroyed, this value (esp_tls_error_handle_t) is freed automatically.

Transport write function

Transport close

Cleanup and free memory the transport

Poll the transport until readable or timeout

Get and clear last captured socket errno Socket errno is internally stored whenever any of public facing API for reading, writing, polling or connection fails returning negative return code. The error code corresponds to the `SO_ERROR` value retrieved from the underlying transport socket using `getsockopt()` API. After reading the captured errno, the internal value is cleared to 0.

Add a transport to the list, and define a scheme to indentify this transport in the list

Set default port number that can be used by this transport

Poll the transport until writeable or timeout

Transport connection function, to make a connection to server

Set transport functions for the transport handle

Captures the current errno

Set websocket sub protocol header

Captures internal tcp connection error This is internally translated to esp-tls return codes of esp_err_t type, since the esp-tls will be used as TCP transport layer

Sets error to common transport handle Note: This function copies the supplied error handle object to tcp_transport's internal error handle object

Set transport functions for the transport handle

Set the user context data for this transport

Set name of interface that socket can be binded on So the data can transport on this interface

Set SSL certificate data (as PEM format). Note that, this function stores the pointer to data, rather than making a copy. So this data must remain valid until after the connection is cleaned up

Set SSL certificate data (as DER format). Note that, this function stores the pointer to data, rather than making a copy. So this data must remain valid until after the connection is cleaned up

Enable the use of certification bundle for server verfication for an SSL connection. It must be first enabled in menuconfig.

Enable global CA store for SSL connection

Set SSL client certificate data for mutual authentication (as PEM format). Note that, this function stores the pointer to data, rather than making a copy. So this data must remain valid until after the connection is cleaned up

Set SSL client certificate data for mutual authentication (as DER format). Note that, this function stores the pointer to data, rather than making a copy. So this data must remain valid until after the connection is cleaned up

Set SSL client key data for mutual authentication (as PEM format). Note that, this function stores the pointer to data, rather than making a copy. So this data must remain valid until after the connection is cleaned up

Set SSL client key password if the key is password protected. The configured password is passed to the underlying TLS stack to decrypt the client key

Set SSL client key data for mutual authentication (as DER format). Note that, this function stores the pointer to data, rather than making a copy. So this data must remain valid until after the connection is cleaned up

Skip validation of certificate's common name field

Set the server certificate's common name field

Set name of interface that socket can be binded on So the data can transport on this interface

Create web socket transport

Set HTTP path to update protocol to websocket

Non-blocking transport connection function, to make a connection to server

Set parent transport function to the handle

Get default port number used by this transport

Set TCP keep-alive configuration

Set TLS protocol version for ESP-TLS connection

Set the list of supported application protocols to be used with ALPN. Note that, this function stores the pointer to data, rather than making a copy. So this data must remain valid until after the connection is cleaned up

Set PSK key and hint for PSK server/client verification in esp-tls component. Important notes: - This function stores the pointer to data, rather than making a copy. So this data must remain valid until after the connection is cleaned up - ESP_TLS_PSK_VERIFICATION config option must be enabled in menuconfig - certificate verification takes priority so it must not be configured to enable PSK method.

Set keep-alive status in current ssl context

Set websocket user-agent header

Set websocket additional headers

Set websocket authorization headers

Polls the active connection for termination This API is typically used by the client to wait for clean connection closure by websocket server

Returns underlying socket for the supplied transport handle

Handles control frames This API is used internally to handle control frames at the transport layer. The API could be possibly promoted to a public API if needed by some clients

Get transport handle of underlying protocol which can access this protocol payload directly (used for receiving longer msg multiple times)

Sends websocket raw message with custom opcode and payload Note that generic esp_transport_write for ws handle sends binary massages by default if size is > 0 and ping message if message size is set to 0. This API is provided to support explicit messages with arbitrary opcode, should it be PING, PONG or TEXT message with arbitrary data.

Returns websocket fin flag for last received data

Returns the HTTP status code of the websocket handshake This API should be called after the connection atempt otherwise its result is meaningless

Returns websocket op-code for last received data

Returns payload length of the last received data

Create a proxy transport

Set the ssl context to use secure element (atecc608a) for client(device) private key and certificate

Set the ds_data handle in ssl context.(used for the digital signature operation)

Changes the configuration of the proxy
