I have downloaded the esp32-cam example and the Soft Access Point example separately and successfully was able to run them. What I’m trying to do is to place the camera in a remote place ad access the streaming from the helm of a boat. I tried to just append one after the other but got error message when compiling. I would appreciate any guidance.

Thanks

@drjoelleon

Here is a link to someone who had a problem in the same area

"You should run the serial output of the crash through the ESP32 Exception Decoder."

 

But you might be having issues with telling the ESP32 to run in 2 different modes at the same time. I am not 100% on this but I believe you can only have it in one mode at the same time and they might be conflicting. That's really just a shot in the dark though.

 

What exactly are you trying to do? I really hope that wasn't the exact code you uploaded. You would need to combine each section with only one setup and one loop. If what you are attempting is use the camera with the ESP as your access point, that will be easy. If that is the case then take your camera sketch and include the following in the appropriate sections:

 

//At the top include
const char* ssid = "yournametoshowhere";
contt char* password = "yourpasswordhere";

//In your setup section
WiFi.softAP(ssid, password);
IPAddress IP = WiFi.softAPIP();
Serial.print("AP IP: ");
Serial.println(IP);
startCameraServer();

//Then remove all existing code that pertains to wifi/AP

There is actually links to how to post code just above the list of Recent Posts.
Perhaps it could be changed to flashing text as no one seems to notice it.

Suggestion:

If you are using the Arduino IDE,
right mouse down Select All, right mouse down Copy as HTML

In your post hit the Enter key to make some lines, then select {;} in top bar above, left mouse click between <p></p> and right mouse button down select Paste,

You defined Builtin_LED but when you used it, it was in all caps. I am posting what I edited from the basic sketch below. It verified but I do not have the hardware to test it.

Hi Joel,

  It appears I was trying to untangle your code at the same time as @madmisha. If the code above works, great, my contribution is redundant. (And the code above looks neater!) I agree with comments above.

I tried to minimise changes, but when I tried to run my version of the code with the obvious bugs removed, it seemed to change the baud rate to the monitor, as it started printing garbage. I confess I didn't spend a lot of time figuring out why. I simply moved the WiFi start until after initialising the camera, which seemed to fix it.

Sorry, I haven't looked into how the LED brightness is actually controlled by the browser, so although it now compiles, I don't know if that bit works. It does however run the usual web server and shows the camera image, so somewhere to start from.

It is 'not obvious', unless you look at the content of some of the ".h" files, but it is only necessary to call about 3, as the others are then automatically included by the the first few. Also, the .h files should normally be included before you get into the code sections. #define and other #xxs are not code.

I'll include my version in case it is still helpful.

Good luck!

I agree wholeheartedly. I am actually a little surprised that the example code just threw it in at that spot. Also, the commenting seems to annoy me too. All I did above was use the example and add softAP that was included in the loop section already. I have a feeling that the HTML LED toggling was actually the example for softAP and is not @drjoelleon's intent. They will have to confirm this though.

OK, I just reread your original post. Here is a new sketch without the LED. It looks like you just want to connect straight to the ESP Cam and view the feed in your browser. This will work. You need a delay in the loop to keep it going.

 

 

#include "esp_camera.h"
#include <WiFi.h>

//
// WARNING!!! PSRAM IC required for UXGA resolution and high JPEG quality
//            Ensure ESP32 Wrover Module or other board with PSRAM is selected
//            Partial images will be transmitted if image exceeds buffer size
//

// Camera model

#define CAMERA_MODEL_AI_THINKER // Has PSRAM

#include "camera_pins.h"

//Enter in SSID and password to access ESP Cam
const char* ssid = "jml's Soft Access Point";
const char* password = "";

//Set what port you want here, 80 is a standard port
WiFiServer server(80);

void startCameraServer();

void setup() {
  Serial.begin(115200);
  Serial.setDebugOutput(true);
  Serial.println();

  //SoftAP Setup
  WiFi.softAP(ssid, password);
  IPAddress IP = WiFi.softAPIP();
  Serial.print("AP IP: ");
  Serial.println(IP);

  camera_config_t config;
  config.ledc_channel = LEDC_CHANNEL_0;
  config.ledc_timer = LEDC_TIMER_0;
  config.pin_d0 = Y2_GPIO_NUM;
  config.pin_d1 = Y3_GPIO_NUM;
  config.pin_d2 = Y4_GPIO_NUM;
  config.pin_d3 = Y5_GPIO_NUM;
  config.pin_d4 = Y6_GPIO_NUM;
  config.pin_d5 = Y7_GPIO_NUM;
  config.pin_d6 = Y8_GPIO_NUM;
  config.pin_d7 = Y9_GPIO_NUM;

  config.pin_sscb_sda = SIOD_GPIO_NUM;
  config.pin_sscb_scl = SIOC_GPIO_NUM;
  config.pin_pwdn = PWDN_GPIO_NUM;
  config.pin_reset = RESET_GPIO_NUM;
  config.xclk_freq_hz = 20000000;
  config.pixel_format = PIXFORMAT_JPEG;
  
  // if PSRAM IC present, init with UXGA resolution and higher JPEG quality
  //                      for larger pre-allocated frame buffer.
  if(psramFound()){
    config.frame_size = FRAMESIZE_UXGA;
    config.jpeg_quality = 10;
    config.fb_count = 2;
  } else {
    config.frame_size = FRAMESIZE_SVGA;
    config.jpeg_quality = 12;
    config.fb_count = 1;
  }

#if defined(CAMERA_MODEL_ESP_EYE)
  pinMode(13, INPUT_PULLUP);
  pinMode(14, INPUT_PULLUP);
#endif

  // camera init
  esp_err_t err = esp_camera_init(&config);
  if (err != ESP_OK) {
    Serial.printf("Camera init failed with error 0x%x", err);
    return;
  }

  sensor_t * s = esp_camera_sensor_get();
  // initial sensors are flipped vertically and colors are a bit saturated
  if (s->id.PID == OV3660_PID) {
    s->set_vflip(s, 1); // flip it back
    s->set_brightness(s, 1); // up the brightness just a bit
    s->set_saturation(s, -2); // lower the saturation
  }
  // drop down frame size for higher initial frame rate
  s->set_framesize(s, FRAMESIZE_QVGA);

#if defined(CAMERA_MODEL_M5STACK_WIDE) || defined(CAMERA_MODEL_M5STACK_ESP32CAM)
  s->set_vflip(s, 1);
  s->set_hmirror(s, 1);
#endif


  startCameraServer();

  Serial.print("Camera Ready! Use 'http://");
  Serial.print(WiFi.localIP());
  Serial.println("' to connect");
}

void loop() {
  // put your main code here, to run repeatedly:
  delay(10000);
}

 

Like before, it passed the verification but I have not tested it on any hardware. I hope this helps and sorry for the confusion.

I tried your sketch and go and error stating the "camera_pins.h" is not defined.

@davee

The sketch did not compile for me. The error was the Camera_pins.h ,no such file directory. Its funny because in the sketch that worked. the compiling was not stopped there.

Is the Arduino that brittle a language that it works and doesn't work for no reason ?
