As stated before, when we connect the ESP32 to a WiFi network, we will be given a local IP. Note that this IP is only valid inside that network and you cannot use it to reach the ESP32 from outside the network. To do so, you need to port forward your router and interact with its public IP. The router will then forward the packets to the ESP32. Note however that the port forwarding procedure may not be trivial and it depends on the router used Upload the WiFiManager project for ESP32. Here is an example to test the Create a new sketch library on the Arduino IDE or a new PlatformIO project and paste the following code. The program calls the autoConnect() method by default to allow the user to choose the WiFi network to which he wishes to connect

This function is what tells the Wifi adapter in our ESP32 that it should be in promiscuous mode. In that same setup function, we are also calling 'esp_wifi_set_promiscuous_rx_cb' with a reference to our 'sniffer' function. This is telling the ESP32 to run this function every time it reads a frame, passing in the information for that frame. You can also see that we have created a struct named 'WifiMgmtHdr' to make it easier for us to work with the header information. In our. The ESP32 comes with improvements all around. T he ESP32 is WiFi capable, like the ESP8266, but also supports Bluetooth LTE, For this example, I am using the SparkFun ESP32 Thing.
