below is tweaked example code for sending image to my server. (I just changed client.connect method)

anyway, when I took pic, then goes to connection failed.
and I logged my server , didn't come any.

as you may can typed http://myforever.herokuapp.com:80/getPic , then comes to my server well.


why I can't connect to my server to send image...?


void camCapture(ArduCAM myCAM){
  //WiFiClient client = server.client();
  WiFiClient client;
  const int httpPort = 80;
  if (!client.connect(http://myforever.herokuapp.com/getPic, httpPort)) {
        Serial.println("connection failed");
        return;
  }
  size_t len = myCAM.read_fifo_length();
  if (len >= 0x07ffff){
    Serial.println("Over size.");
    return;
  }else if (len == 0 ){
    Serial.println("Size is 0.");
    return;
  }
 
  myCAM.CS_LOW();
  myCAM.set_fifo_burst();
  #if !(defined (ARDUCAM_SHIELD_V2) && defined (OV2640_CAM))
  SPI.transfer(0xFF);
  #endif
  //if (!client.connected()) return;
  String response = "POST /api/device/image HTTP/1.1\r\n";
  response += "Content-Type: image/jpeg\r\n";
  response += "Content-Length: " + String(len) + "\r\n\r\n";
  //server.sendContent(response);
 
  Serial.println("conected to the server");
  client.println(response);
 
  static const size_t bufferSize = 4096;
  static uint8_t buffer[bufferSize] = {0xFF};
 
  while (len) {
      size_t will_copy = (len < bufferSize) ? len : bufferSize;
      SPI.transferBytes(&buffer[0], &buffer[0], will_copy);
      if (!client.connected()) break;
      client.write(&buffer[0], will_copy);
      len -= will_copy;
  }
 
  myCAM.CS_HIGH();
}[/s]

Code: [Select]
  if (!client.connect(http://myforever.herokuapp.com/getPic, httpPort)) {
The server name is NOT http://myforever.herokuapp.com/getPic.

It MIGHT be myforever.herokuapp.com.
