ESP32 Forum

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.

WiFi.begin(ssid, password);
int i=0;
while (WiFi.status() != WL_CONNECTED && i++<=10)
{
delay(1000);
i=i+1;
if (i>11)
{Serial.print("I don´t connect......");
ESP.restart();
}

Sorry but I am not using arduino. and also its not the proper solution to restart esp.

Unfortunately it is hard to diagnose issue like this, you need logs from the time of disconnect. You can try with different esp-idf versions and different APs, see how common the problem is. You may even need WiFi sniffer captures to solve it.

As I saw logs w.r.t same issue, ESP32 gets connected to my Router with no IP (may be SYSTEM_EVENT_STA_GOT_IP event not generated) and it stucks until we switch it OFF and ON again. why does it happen. what is the reason behind it.

It is already enabled in my configuration by default.( CONFIG_LWIP_DHCP_DOES_ARP_CHECK ).

Enabled or disabled?
