- esp_wifi_set_scan_parameters() : Used to set the default scan parameters to be used
while scanning. These parameters will be used for all scans conducted by station
including connect scan. Parameters provided through esp_wifi_scan_start() override the
default parameters for that scan only
- esp_wifi_get_scan_parameters(): Used to get the current default scan parameters.
- Shows use of roaming app through dedicated example : roaming_app_example.
- Changes the location of the earlier roaming example by moving it into the roaming_11kvr.
- Please note that this feature is still experimental and still being optimised
and tuned.
- Any scanning currently updates the bss table held by supplicant anyway,
but the time record used to maintain the recency of the last scan is
only updated by supplicant issued scans. Updating the last scan time
for application trigerred scanning will prevent the needless scanning
by supplicant if there has been an application trigerred scan in
the time diff threshold(currently 10s).
- Add default durations to supplicant issued scans based on results from
initial experiments where probe response times were recorded in a
significantly noisy environment. It was noticed that within 70ms
we receive over 80% of the responses 90% of the time
- Clear the bssid set flag and channel in supplicant disconnect handler as this
can cause the station to recursively connect to the wrong AP in case
roaming through BTM mechanisms fails.
- Fix issue with incorrect blocking time calculation when blocking scan
issued for a single channel.
- Deprecate the existing esp_rrm_send_neighbor_rep_request() API
- Adds a new API to send neighbor report requests esp_rrm_send_neighbor_report_request().
This replaces the older API's callback procedure with a new Wi-Fi
event that is posted when the neighbor report is received.
This moves the execution of the callback from supplicant
context to freertos context.
- Add the ability to specify the specific channels and the
in wifi_config_t.
- Adds warning that discourages setting bssid and channel in sta_config
when btm/mbo is enabled and supported by the network.
- Fix issues with reporting authmodes of FT supporting APs during scanning.
- Additional typo fixes in the public header files
- WIFI_REASON_NO_AP_FOUND_W_COMPATIBLE_SECURITY will be reported for the following
reasons
-- AP has PMF required but station is not configured for pmf capable/required.
-- Station has PMF required but AP is not configured for pmf capable/required.
-- The AP is using unsupported group management/pairwise ciphers
-- OWE not enabled by station for found OWE AP
-- AP RSNXE parsing failed in supplicant
-- AP is in Independent BSS mode
- Fixes issue with connecting and discovering WEP APs
- Expsnds the reasons for trigerring a disconnect using
REASON_NO_AP_FOUND_WITH_COMPATIBLE_SECURITY
-- SAE-PK configured as compulsory in sta config but disabled for the AP
-- SAE-H2e configured as compulsory in sta config but disabled for an AP
that has authmode as WPA3-PSK or WPA3-WPA2-PSK.
-- Open AP found but we have set password or enabled enterprise mode.
-- SAE H2E only ap but we have SAE HnP setup in config.
-- WPA3-EXT_PSK AP but SAE-H2E disabled in config
Adds 3 more ddisconnect reasons in case of No AP found.
1. REASON_NO_AP_FOUND_IN_RSSI_THRESHOLD : AP rejected because it did
not meet rssi threshold.
2. REASON_NO_AP_FOUND_IN_AUTHMODE THRESHOLD : AP rejected because it
did not meet security threshold.
3. REASON_NO_AP_FOUND_WITH_COMPATIBLE_ SECURITY : AP rejected because
of incompatible security configuration. These situations could include
-- bss offerring WEP, but our password is not WEP compliant,
-- Encrypted AP bss but we have no password config set.
-- AP is Enterprise but we have not setup enterprise config and vice versa
Closes https://github.com/espressif/esp-idf/issues/5957
- Fixes issue wheere beacon timeout would get triggerred multiple times
leading to a m f probe req.
- Fix missing PMKSA flush scenarios.
- Fix wrong AID assigned to station when multiple stations try to connect
simultaneously with mixed order of auth-request and assoc-request frames.
- esp_supp_dpp_init : Ensures that the mode is set to station before
the API call.
- Ensures that dpp follows the path of init(esp_supp_dpp_init) ->
bootstrap(esp_supp_dpp_bootstrap_gen) -> listen(esp_supp_dpp_start_listen)
by returning errors if any of them is invoked out of order.
-Merges the addition of extended caps IE for assoc req, probe resp
and beacons in a single place. This ensures that there are no
duplicate Extended Caps IE in the frame. Moves the capability
indication for BTM and HT20/40 from supplicant to wifi libs.
-Fix issue with frequent disconections when scanning for only a single
channel.
-Prints error message and returns ESP_ERR_NOT_SUPPORTED in case
esp32c2 tries to set bandwidth to HT40.
Fix crash in sending new RRM neighbour report requests by removing
the call to neighbour report request timeout callback in case of
already ongoing neighbour report request timer.
Fix crash due to premature deallocation of neighbour report elements
by scan_done. Post event to btm_rrm_t task to handle scan_done serially
rather than when btm_rrm_t task is processing btm request rx frame.
1) Fix issue during split scan to allow for data tx.
2) Fix issue when parsing wpa_ie to set correct authmode when AP
supports both WPA_EAP and WPA_EAP_SHA256 authmode.
Closes https://github.com/espressif/esp-idf/issues/11202
3) Fix an occasional crash during sta roam.
4) Add home_channel_dwell_time to wifi_scan_config_t. This allows
configuration of the time spent between scanning consecutive
channels for tx.
Add validation for group data cipher, pairwise cipher and AKM Suites to
ensure correct ciphers are supported by AP during 192-bit Enterprise
connections.
Current esp_wifi_get_config doesn't return correct value of h2e config which will cause h2e config to be overwritten in Station connected handler.
Add one preventative condition to take care of this.
During the wifi deinit last_scan_res_used is not set to 0 which will cause it be used directly after reinit.
Added changes which will set it to 0 during init and deinit.
esp-wifi: Restores station status to connected when no other AP is found for roam
Closes WIFI-4785
See merge request espressif/esp-idf!20120
\[WiFi\]Fixed the bug that station connected to an AP already connected caused subsequent scan fail.
