esp32-wifi-manager: crash on connect

Prerequisites

  • I have written a descriptive issue title
  • I have verified that I am using the latest version of esp32-wifi-manager
  • I have searched open and closed issues to ensure it has not already been reported

Description

I’m not sure if this is a bug, or just something i did wrong.

When the esp boots it goes to the wi-fi manager just fine, but when i try to add a connection it seems to crash, the culprit for the error seems to be esp_wifi_scan_start(&scan_config, false) at line 1020 (in master branch, 981 on the commit the project is using, but i have tried both versions without success), but I am not sure what to make from it.

Steps to Reproduce

  • clone esp32-nixie-clock
  • compile with latest master branch of esp-idf (ESP-IDF v4.3-dev-1197-g8bc19ba89)
  • erase flash and flash esp
  • connect to AP
  • add new connection

System Configuration

I am trying to use the code from esp32-nixie-clock (I know it’s a different project but the problem seems to be the wi-fi manager), with custom hardware I made here, I don’t see a reason to suspect hardware.

Found the reason for crash: Scan cannot be started when simultaneously trying to connect to station (esp_wifi_scan_start returns ESP_ERR_WIFI_STATE, which ESP_ERROR_CHECK doesn’t handle well). I first tried to check additional flags (WIFI_MANAGER_REQUEST_STA_CONNECT_BIT and WIFI_MANAGER_REQUEST_RESTORE_STA_BIT) but I still got occasional race conditions, so I check for ESP_ERR_WIFI_STATE separately anyway and let ESP_ERROR_CHECK() handle the rest.

			case WM_ORDER_START_WIFI_SCAN:
				ESP_LOGD(TAG, "MESSAGE: ORDER_START_WIFI_SCAN");

				/* if a scan is already in progress this message is simply ignored thanks to the WIFI_MANAGER_SCAN_BIT uxBit */
				uxBits = xEventGroupGetBits(wifi_manager_event_group);
				if (! (uxBits & WIFI_MANAGER_SCAN_BIT) ){
					if (! (uxBits & ( WIFI_MANAGER_REQUEST_STA_CONNECT_BIT | WIFI_MANAGER_REQUEST_RESTORE_STA_BIT) ) ) {
						esp_err_t res = esp_wifi_scan_start(&scan_config, false);
						if (res==ESP_ERR_WIFI_STATE) {
							// This might happen when connect retry is attempted while AP scan starts.. Just ignore it
							ESP_LOGE(TAG,"Wifi still in connect mode whan starting scan!");
						} else {
							// handle other errors
							ESP_ERROR_CHECK(res);
							xEventGroupSetBits(wifi_manager_event_group, WIFI_MANAGER_SCAN_BIT);
						}
					} else {
						// Cannot scan while connecting to AP
					}
				}
