 Hello everyone,
I am getting wifi disconnect issue from very long time.
As I kept my ESP32 live for long time, it disconnects and not getting connected to the configured SSID and PASSWORD again till switch it OFF and ON again. I am using esp-idf v3.1.3.

Please help me to resolve this issue.
Thanks in advance.
Why not just reboot when it fails after xxx retries? The ESP32 boots so quickly that it shouldn't be too much of an issue.

I am using esp this way already. I am confused that its a hardware issue or esp idf. or it may be not issue from esp side overall.
I have collected some logs. can u please check it and let me know if you get some from that.

It has not been released for 3.2 but you should either request a patched version on that GitHub issue or try the master version. It might or might not be related to your problem.
