Awesome project ❤ going to try and make a small pocket camera for a paramotor to see the remaining fuel in flight. Thanks for sharing and posting a great tutorial
Hi, first thank you very much for your kind words :) I finally managed to get an image from the camera directly to the screen, I'm just lacking some time to make a video on it. so if you want to make one with just one board .... I hope to make a video on it soon :)
Sounds cool, I never used one of thus, I thought of ordering one. I'm working on a new video, showing streaming mjpeg and finding the stream on the local network. just been busy, so it takes me time to get it done :)
@@talofer99 Id like to see that! I ended up using th-cam.com/video/aIxaR6legnw/w-d-xo.html for a live video stream. Only downside is that it uses the watch as an access point, would be nice to just find it on a general network ^.^ is also gonna be my next project xD
@@smokeysky cool, I was guessing some one did something like that, I wonder how it's done will look into the code there. I still did not find the time (super busy) to make the video - the camera is on the table for over 3 weeks now :)
esp-now is using the wifi.... but in close network. It can be done over wifi, the camera library has an example of making the image available over http. It can be done over BLE as well, it will probably be the same speed as esp-now I done it also via UART but it was way too slow.
Thank you. Its an interesting Idea, I already got them both working one the same board ... so can stream the image to the screen and make a door bell will be super cool :)
I love the ESP32-CAM. I am researching how to connect ESP32-CAMs via wifi or ESPNOW such that several cameras can capture an image and transmit to a central ESP32-CAM so that it can save the photo to the SD card. This would give a central location to collect photos from an area. Like a animal refuge area, several trail cams collecting images and sending to a single SD card. Is that a project you might take on for a video?
Awesome project I subscribed. I really want to make a system in which the images captured by the esp32 cam will be transferred to a separate esp32 board and then shown on a screen. but it should be a wired circuit so that it could also work without wifi. please make a video on it.
@@talofer99 I have no problem with the speed but can you make a separate video in which you make it step by step because I am a beginner. It would really help a lot 🙂
Wow, this project is super cool! Will try this out soon. Btw just a quick question - approximately what was the maximum size of the image you were able to transmit? Would it be able to handle say 200-300 KB images? Thanks again for this interesting project.
Thank you very much :) The espnow transmit limit is 250 Bytes, place some CRC on top and part number I used 240 Bytes for the actual image data. So in order to transmit 240K (to make it easy) you will need a 1K packages ....so it's doable - not practical. I got on my table the setup with the display connected to the esp32 camera board - which took me some time to figure out - so it steams the camera to the screen. got to find time to make a video on it as well.
@@talofer99 cool, thanks for clarifying that. I'll give it a try and see how it goes. The boards will be pretty close to each other. Not sure if that helps with reliable transmission. Another option would be bluetooth but I won't bet on reliability of bluetooth on cheap devices though. Even a wired connection to send the pictures across to another ESP32 will be interesting :)
Sorry for the late reply. I did try it with Serial, not sure id I mentioned it in the video, and it was slower . This is not surprising since the data rate of transfer is 2.4ghz .... so even if you get half the speed, its way faster then UART. And I would go with BLE and not Classic Bluetooth, and I think it might work, I used to upload code using BT few years back, and no issues.
@@talofer99 Oh ok cool! I'll give it a try with classic BT. I'll just need to check how reliably it can connect, send every time. I remember I had once read a post where someone was able to upload code to esp32 at 922190bps. Again this can only be confirmed once I try it out. I am hoping to make some time for testing both the methods - classic BT and Serial at 922190bps! :) Thanks once again for the ideas and the tips.
Hey, this video was very helpful. I am currently working on a similar project, but I dont use a monitor. Instead I have to send the photo which was saved as a SPIFF via a telegram bot to a telegram chat. Do you know if this is possible? Could you maybe tell me which telegram bot sending command I need in this case?
Hi, I never tried to send something in telegram with esp. I know the image can be sent - but not sure how to do it on telegram. If it possible, you are only a google search a way from it :)
@@awaagrikh8331 If you want to be on the safe side and in a better chance to recover the file, I would got with a simple CRC16 for each package. add 2 bytes in the end for the CRC.
Sorry, I never really create one, unless its super complicated. If you need to know how to connect the screen, you can watch it on this video th-cam.com/video/NK0Sx49XQdI/w-d-xo.html
@@talofer99actually I need to know how to wire a push button with the ESP32-CAM because I connected the button to the RX pin, but the ESP still can't capture a photo using the push button.
I can see you asked about the reset of the unit in the notification but can not see the actual comment So make sure you set the Flash Frequency to 40 not 80 and then upload the code.
@@talofer99 ya, there are some body did it, I can‘t copy it works, actually just noise, almost can see any nothing. BTW. is the Payload limited to 250 bytes obstacle the stream here?
@@summerfun6114 if you refer to stream the image to a screen ? then no - there is no real limit here. If you refer to the ESPNOW, then yes, you can barely get 1-2 images per second.
Since the pay load limit per messahe is 254 byte I think its not really doable. I seen a project when the camera esp32 was acting as AP and the other unit showed the stream.
@@talofer99 is there any way to stream a video from esp cam without wifi? And the method you are talking about, how can it be done is there any reference?
Sir I have a problem to run the system correctly. The only difference about hardware is display. I've changed the display class settings into the device's that I'm using. Should I change another thing?? The image is seen from the display but it isn't fill all of it and it is meaningless.
hello! very nice and unique tutorial, Thanks for the effort you put into making the video. i'm having some trouble writing the code for a similar application, can we get the code please it would make my life way easier.
Hi, Thank you very much. Sure, it actually made me finally upload the code to git, here is a link github.com/talofer99/ESP32CAM-Capture-and-send-image-over-esp-now
Great video! I have the same arduino board for the display. Would you be able to confirm what pin goes to what? This is the bit that i am struggling with. Thanks.
Thank you :) The SPI pins are GPIO 23 is the mosi GPIO 18 is the clock GPIO 05 is the SS You can see the pinout here www.mischianti.org/2021/02/21/esp32-wemos-lolin32-high-resolution-pinout-and-specs/ For the rest of the pins there is the table from the example : * ESP32 various dev board : TFT_CS: 5, TFT_DC: 27, TFT_RST: 33, TFT_BL: 22 Hope it helps out .... if not let me know :)
Loved the video, thank you for sharing your project and code, you mentioned that you are looking at streaming video, so I have joined your channel in the hope of seeing more thanks, Bob in the UK
Thank you very much :) I did look into the video streaming and I know that in theory its possible but did not had the time to dive deep into it.

Nice video. However, can you make another video showing how to display what's the ESP32 CAM is seeing with only 1 display? Instead of streaming from another ESP32
Thank you very much. I tried it in the house, and I got about 6 meters. Didn't try it in any longer distance it would be interesting to test. From doing a quick read people are talking about long ranges "possible" with esp-now.

So, looks like ESP-NOW protocol has not enough transfer speed for streaming video from ESP32 cam, right?
I agree a d its not really the speed as the limitation on the package size.

I am researching how to connect ESP32-CAMs via wifi or ESPNOW such that several cameras can capture an image and transmit to a central ESP32-CAM so that it can save the photo to the SD card.

I done part of it in this video
th-cam.com/video/wmH6TewY3YQ/w-d-xo.html
All that is left is to save it.
This is great. I'm trying to save the images on the SD-card of the receiver. Instead of using the SD-card as a buffer I want to use SPIFFS.
I was not able to get the spiff working on the esp32-cam.
If you do get it to work let me know.

Hi, do your code have mechanism like CRC check to verify the file is not corrupted at the receiver end?
No, it does not have CRC mechanism in it.
Yes that means that the file can be corrupted on the transfer.
@@talofer99 what do you suggest for archiving this? Calculate CRC and send it in the last packet?
@@awaagrikh8331 If you want to be on the safe side and in a better chance to recover the file, I would got with a simple CRC16 for each package. add 2 bytes in the end for the CRC.
