Expand description
@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 |
