Dear friends,

Before I start learning I want ask if it is possible to send the image (pic from camera) to FTP - using this great tutorial?

Thank you

Hello Petr4ppc (and everyone else), sorry for my delayed response on the Camera Library. I have a 2 year old, full time job, and also in the USA - so it's all crazy

p4ppc, I don't see why you can't sending via FTP. I'm sure you can refer to Erel's FTP post to setup the FTP part. Depending on how big your image is, you may be to send an in memory copy from the camera, else it will be good to save to SD Card (or perhaps flash if that's practical) and upload from there.

Dear Miker2069,

first thank you for your NICE tutorial and very good work.
Thank you for your advice (i thought that FTP lib for esp8266 can not be used in ESP32 - I have asked for certain because of possibility of damaging my esp32).
I go to do some tests, one more - thank you very much

I also want to do the same thing but not success, It would be great if anyone can give some example if you can make it work. Thanks!

Hypnos,

did you tried esp8266 FTP lib? I have tested it, but I can not connect to FPT server.

Now, I know this is an old thread (LOL), but ...
I just spent two hours trying to get this to work.
I have a FTDI programmer and an ESP32 Camera module. I wired it exactly as indicated in the thread.
Finally, determined. I could only program the esp32 at 3.3 volts. At 5 volts I got a bunch of errors.
But, once programmed the B4R App only ran at 5 volts not the programming voltage of 3.3 volts.
I am pretty sure I downloaded and did this a year ago and did not have the same problem.

I reread post #2 maybe that is what Miker2069 is indicating, but I didn't read it that way.
I.E Program at 3.3V and run Camera Board/App at 5 Volts.
Anyway if anyone else tries this and has a problem that might be your issue.

Thanks Miker2069, code works great as is !
B4X it is all about the journey not the destination. LOL

Hi
I think I'm missing something - the live streaming works just fine, if I try the pic taking I get the following Log message and nothing on the uSD.
Other than removing the gray scale option (commenting out) nothing else has changed in the B4R script - That I downloaded earlier today

Hope you can help

I get that too once in a while if it is taking a long time for the picture to display in the browser.
I am using the latest FireFox browser. The streaming seems extremely slow to me.

What frame rate are you getting and what resolution ? VGA SVGA ?
