@brief MQTT error code structure to be passed as a contextual information into ERROR event

Important: This structure extends esp_tls_last_error error structure and is backward compatible with it (so might be down-casted and treated as esp_tls_last_error error, but recommended to update applications if used this way previously)

Use this structure directly checking error_type first and then appropriate error code depending on the source of the error:

| error_type | related member variables | note | | MQTT_ERROR_TYPE_TCP_TRANSPORT | esp_tls_last_esp_err, esp_tls_stack_err, esp_tls_cert_verify_flags, sock_errno | Error reported from tcp_transport/esp-tls | | MQTT_ERROR_TYPE_CONNECTION_REFUSED | connect_return_code | Internal error reported from MQTT broker on connection |

Fields§

§esp_tls_last_esp_err: esp_err_t

< last esp_err code reported from esp-tls component

§esp_tls_stack_err: c_int

< tls specific error code reported from underlying tls stack

§esp_tls_cert_verify_flags: c_int

< tls flags reported from underlying tls stack during certificate verification

§error_type: esp_mqtt_error_type_t

< error type referring to the source of the error

§connect_return_code: esp_mqtt_connect_return_code_t

< connection refused error code reported from MQTT* broker on connection

§esp_transport_sock_errno: c_int

< errno from the underlying socket
