AutoConnect not trying to connect to all known SSIDs

[miroslavpetrov]

Hello,

I am experiencing the following issue:

I have saved two SSIDs on the ESP32 and it auto connects only to the last used SSID. If for example I lastly used it with SSID_1 and I turn on the ESP32 near SSID_2(where SSID_1 is not in range) it only tries to connect to SSID_1 and does not try to connect to SSID_2. After that I open the captive portal and select SSID_2 from open ssid menu and it connects as expected. And after that if I again try to connect to SSID_1 when SSID_2 is not in range the issue is the same.

To sum it up: The ESP32 does not try to connect to all known SSIDs(like your smartphone does for example). It only connects to the last used known SSID

@miroslavpetrov See the logic sequence of AutoConnect::begin, AutoConnect first executes WiFi.begin with no arguments. It tries to connect to the most recent SSID stored by the ESP-IDF SDK. As far as your situation is concerned, AutoConnect is working as expected.

If you want to try to connect to SSID_2 when the connection to SSID_1 fails, the autoReconnect setting should help. See the AutoConnectConfig::autoReconnect section of the documentation.

In such cases, finding the AutoConnectConfig settings often results in the expected behavior. However, AutoConnectConfig has many options, and you may need to try several times to achieve the desired configuration.

I move this topic to Discussions because of its potential efficacy in alerting other users.
