When an ESP32 connects to a network, it will obtain an IP address dynamically using the DHCP (Dynamic Host Configuration Protocol). Every time the ESP32 restarts and re-connects to the network, it’s guaranteed that it’s going to take the same IP address again. The IP address assigned ...
It has a default IP address of 192.168.4.1 and it will provide DHCP services to the externally connected devices. The default IP address can be changed if it conflicts with existing devices. This allows the ESP32 to create its own IP network, independent of any existing WiFi networks. You ...
Try to refresh the DHCP client list on your router. Reply Sandy Riach March 8, 2021 at 12:22 pm Hi, Sorry for the delay. I rebooted my router and lo and behold the changed hostnames appeared – thank you Sandy Stéphane Calderoni February 19, 2021 at 12:34 pm I wanted to po...

Reconnect your ESP32 to a Wi-Fi network after losing the connection. Reconnect when the ESP32 loses Wi-Fi signal, router restarts, or other situations.
