How to make a functional wifi access point with wifi connection.

[Pyshco]

This would very basic, but, i'm new working on the wifi side of the ESP32, Can you guys help me with a example or else?

This should get you started: https://esp-idf.readthedocs.io/en/lates ... /wifi.html

Edit: Oh, just say this is in the Arduino section of the forum. Then that link might not help you.

Search with ESP32 MODE APSTA (Access Point and Station). or follow this link:

here you go.. just tested and it works fine.. It first sets the wifi mode to both access point and station. then starts the access point and then connects to a network.. However, If I use a configuration like accesspoint name and secret it doesn't work when set the mode as WIFI_AP_STA 'needs some work here'. Otherwise it is working perfectly fine..

Arduino code for esp32:

Code: Select all

#include <WiFi.h>
#include <WiFiAP.h>


const char* ssid     = "home wifi name"; // the ssid/name of the wifi, the esp will be connected to
const char* password = "home wifi password"; // the password of that wifi

const char* assid = "espAccessPoint";
const char* asecret = "hello";

void setup(){
  Serial.begin(115200);
  
  WiFi.mode(WIFI_AP_STA);
 

  //access point part
  Serial.println("Creating Accesspoint");
  WiFi.softAP(assid,asecret,7,0,5);
  Serial.print("IP address:\t");
  Serial.println(WiFi.softAPIP());

  //station part
  Serial.print("connecting to...");
  Serial.println(ssid);

  WiFi.begin(ssid,password);

  while(WiFi.status() != WL_CONNECTED){
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());   
  
}

void loop(){
  
 
 }

Hope that helps

Once I successfully set up an AP on my ESP32 and connected it to my router, can I log the data I am receiving and re-sending? Or it can only act as a bridge between the external device and my router?
The device is a Sonoff Pow, which sends its readings to chinese servers without logging them, and which I usually can only read by an android app, but I would like to add a local logging feature.

I am a bit new in using ESP32, but I need to use it's AP+STA capabilities. The problem is that when I tried the code that you give, there was an error. The error happened when I tried to connect my android phone to the ESP32 via wifi.

The error is as follows:

E (28543) event: mismatch or invalid event, id=63
E (28544) event: default event handler failed!
dhcps: send_nak>>udp_sendto result 0
dhcps: send_offer>>udp_sendto result 0

Any help is very much appreciated. Thank you in advance.
