This comment is to indicate that only one event will come after calling esp_wifi_set_rssi_threshold(), for getting a second event esp_wifi_set_rssi_threshold() needs to be called again.
esp_err_t esp_wifi_set_rssi_threshold(int32_t rssi)
Parameters
rssi – threshold value in dbm between -100 to 0
Returns
-
ESP_OK: succeed
-
ESP_ERR_WIFI_NOT_INIT: WiFi is not initialized by esp_wifi_init
-
ESP_ERR_WIFI_ARG: invalid argument
esp_event_handler_register(WIFI_EVENT, WIFI_EVENT_STA_BSS_RSSI_LOW,
&esp_bss_rssi_low_handler, NULL)
