Cant connect to Wifi

[slipx06]

Tried both the esp32-cam and esp32-cam-allframes sketches but in both instances I'm unable to connect to the WIFI network. The following output is from the serial monitor using an AI thinker board. Any ideas?

I assume you replaced this with your credentials:

/*
  Next one is an include with wifi credentials.
  This is what you need to do:
  1. Create a file called "home_wifi_multi.h" in the same folder   OR   under a separate subfolder of the "libraries" folder of Arduino IDE. (You are creating a "fake" library really - I called it "MySettings").
  2. Place the following text in the file:
  #define SSID1 "replace with your wifi ssid"
  #define PWD1 "replace your wifi password"
  3. Save.
  Should work then
*/
#include "home_wifi_multi.h"

and the credentials are correct.
Remember - esp32 cannot connect to 5Ghz networks.
Are you too far from the AP? Esp32-cam antennas are not very robust.

[slipx06]

Yes I've updated with the correct credentials and I'm connecting to a 2.4Ghz network. Tried a different sketch and it connected fine so not sure.

[arkhipenko]

Do you provide ESP32 with enough power?

[slipx06]

Yes. Using a dedicated 5v 2A power supply

[arkhipenko]

I have not seen these errors before. Try googling it?

E (5536) wifi: Expected to init 16 rx buffer, actual is 9
E (5554) wifi: Expected to init 16 rx buffer, actual is 0

It obviously works on my end.
Do you have another esp-cam you can test this on?
I noticed that they are not the same, depending on where you order from. Some work better than others.

[slipx06]

I ordered 2 boards. Same error on both of them. Will dig a bit more

Try just a simple sketch with wifi and nothing else. If that works, then we can look at my code. If that also does not work, the problem is elsewhere...

[slipx06]

Loaded up a simple sketch with wifi only and it connects to wifi. See below. Using the same code in your sketch and I get the wifi error pasted above

#include "WiFi.h"
 
const char* ssid = "xxxx";
const char* password =  "xxxxx";
 
void setup() {
 
  Serial.begin(115200);
 
  WiFi.begin(ssid, password);
 
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.println("Connecting to WiFi..");
  }
 
  Serial.println("Connected to the WiFi network");
 
}
 
void loop() {}

Managed to get your sketch to work. Like you said some boards are better than others. Would only connect with the following image settings. I also changed the code to handle the wifi ssid and password as per the example sketch I posted earlier but not sure that made any difference.

.frame_size     = FRAMESIZE_VGA,
.jpeg_quality   = 10,
.fb_count       = 2
