Wi-Fi

This document outlines the Wi-Fi related breaking changes in release v6.0.

Removed Functions and Types

The following functions and types have been removed.

  • DPP:

    • The DPP event callback esp_supp_dpp_event_cb_t and event enum esp_supp_dpp_event_t have been removed. Please use Wi-Fi events directly (e.g. WIFI_EVENT_DPP_URI_READY, WIFI_EVENT_DPP_CFG_RECVD, WIFI_EVENT_DPP_FAILED).

  • RRM: The function esp_rrm_send_neighbor_rep_request has been removed. Use esp_rrm_send_neighbor_report_request instead.

  • Antenna Configuration:

    • The functions esp_wifi_set_ant_gpio, esp_wifi_get_ant_gpio, esp_wifi_set_ant, and esp_wifi_get_ant have been removed. Please use the equivalent functions from esp_phy component: esp_phy_set_ant_gpio, esp_phy_get_ant_gpio, esp_phy_set_ant, and esp_phy_get_ant.

  • ESP-NOW: The function esp_wifi_config_espnow_rate has been removed. Use esp_now_set_peer_rate_config instead.

Removed Variables, Macros and Enum Values

  • Authentication Modes: The authentication modes WIFI_AUTH_WPA3_EXT_PSK and WIFI_AUTH_WPA3_EXT_PSK_MIXED_MODE have been removed. Use WIFI_AUTH_WPA3_PSK instead.

  • Neighbor Report Event: In the wifi_event_neighbor_report_t structure, the report field has been removed. Please use the n_report field instead, which is a flexible array member.

  • Wi-Fi Interface: The header file components/esp_wifi/include/esp_interface.h has been removed. The wifi_interface_t enum is now defined in components/esp_wifi/include/esp_wifi_types_generic.h. The enum values (e.g. WIFI_IF_STA, WIFI_IF_AP) are no longer defined based on ESP_IF_WIFI_STA, ESP_IF_WIFI_AP, etc.

  • Wi-Fi Interface Macros: The macros ESP_IF_WIFI_STA and ESP_IF_WIFI_AP have been removed. Please use the enum values WIFI_IF_STA and WIFI_IF_AP directly.

  • Wi-Fi Disconnection Reasons: The disconnection reason codes WIFI_REASON_ASSOC_EXPIRE, WIFI_REASON_NOT_AUTHED, and WIFI_REASON_NOT_ASSOCED have been removed. Please use WIFI_REASON_AUTH_EXPIRE, WIFI_REASON_CLASS2_FRAME_FROM_NONAUTH_STA, and WIFI_REASON_CLASS3_FRAME_FROM_NONASSOC_STA respectively.

  • NAN:

    • Field svc_info from structures wifi_nan_publish_cfg_t, wifi_nan_subscribe_cfg_t, wifi_nan_followup_params_t, wifi_event_ndp_indication_t, wifi_event_ndp_confirm_t has been removed. Please use the equivalent fields ssi and ssi_len instead.

    • Field peer_svc_info from structure wifi_event_nan_receive_t has been removed. Please use the equivalent fields ssi and ssi_len instead.

  • FTM: Field use_get_report_api from structure wifi_ftm_initiator_cfg_t and field ftm_report_data from structure wifi_event_ftm_report_t has been removed. Please use esp_wifi_ftm_get_report to fetch raw FTM report data instead.

Modified Functions and Types

The following Wi-Fi functions have been modified.

  • DPP: The function esp_supp_dpp_init no longer accepts a callback and should be called as esp_supp_dpp_init(void).

  • WPS: The function esp_wifi_wps_start no longer accepts a timeout_ms argument. It should now be called as esp_wifi_wps_start(void).

  • NAN: The function argument ndp_resp_needed of esp_wifi_nan_publish_service has been moved to structure wifi_nan_publish_cfg_t.
