Esp32cam sd google drive

[Vicentetomas]

Hi,

First of all. Congrats for your work. I’m not sure if this is the right place to put this comment. Regarding the Esp32cam sd google drive. Is it possible to give me an idea how to implement the follow? Sometimes I don’t have an internet connection. I would like to store the images in the sd and when internet connection is on then upload all the files to the drive.

I hope you can help me how to do it. Thank you for your time.

You can create a file "list.txt" in SD to record the uploaded files name. If the images in SD are not in the list, upload them.

Hi, also from my side congrats to this awesome "OPUS". I have the same issu with upload from SD card to Google Drive. I cant manage to imploy the .jpeg file from SD instead of camera fb->buf and fb->len

`
if(client_tcp.connect(myDomain, 443)) {
Serial.println("Connection successful");
// ############### here
char *input = (char *)fb->buf;
char output[base64_enc_len(3)];
String imageFile = "data:image/jpeg;base64,";
// ############### and here
for (int i=0;i<fb->len;i++) {
 base64_encode(output, (input++), 3);
  if (i%3==0) imageFile += urlencode(String(output));
}
String Data = myLineNotifyToken+myFoldername+myFilename+myImage;

client_tcp.println("POST " + myScript + " HTTP/1.1");
client_tcp.println("Host: " + String(myDomain));
client_tcp.println("Content-Length: " + String(Data.length()+imageFile.length()));
client_tcp.println("Content-Type: application/x-www-form-urlencoded");
client_tcp.println("Connection: keep-alive");
client_tcp.println();

client_tcp.print(Data);
int Index;
for (Index = 0; Index < imageFile.length(); Index = Index+1000) {
  client_tcp.print(imageFile.substring(Index, Index+1000));
}

` Could you put us on the right track ? If you can, i could complete my little project and share my upload handling here. Thanks again for your great job.

Thank you so much, fustyles. Unfortunately i can't make the sketch run. I get a guru meditation and reboot on this line

fileinput[fileSize] = '\0';

Seems the Guru appears because of a wrong String usage, but i am not so experienced in coding. I also tried a lot of different jpeg images and different AI Thinker esp32-cam boards I use Arduino IDE 1.8.15 and esp 1.0.6 (latest) What am i doing wrong ? Am i missing a custom string library? Thank you so much for your support.

[fustyles]

I think the error cauesd by other reasons. Did you modify my code?

[Rudolf10000]

No , i did not modify. I installed the exception decoder and got :

PC: 0x400d0c4f: sendSDImageToGoogleDrive(String) at C:\Users\rwolf\Documents\Arduino\Sketchbook\ ESP32-CAM_SD_GoogleDrive/ESP32-CAM_SD_GoogleDrive.ino line 177 EXCVADDR: 0x0002b3a5

This is Line 177 - fileinput[fileSize] = '\0';

Ater reading blogs about strings, i tried a lot of things, but without any result. Any idea what i am doing wrong ? I've never used malloc before. Could that be a reason ?

[fustyles]

Please email your sketch to me. france.fu@msa.hinet.net

The sketch compiled well for me and my friends. You may need to update the latest supported Visual C++ redistributable packages. Try to update your computer OS to the latest version. Does your computer install Microsoft OS? Mine is Microsoft OS.

[fustyles]

Please try to remove all Chinese words in the sketch and compile again.

Hi @fustyles thanks for your video and code! I am getting a: "Guru Meditation Error: Core 1 panic'ed (LoadProhibited)" in the line: base64_encode(output, (input++), 3); after commenting out the line: fileinput[fileSize] = '\0'; Where I get a core panic "Store Error" just like @Rudolf10000 stated.

Any ideas of what might be happening? I had try with different sd cards has no changes, same errors described above, also no chinese words are in the sketch.
