I can connect the XIAO ESP32S3 Sense port and upload ai model in it, but I can’t open the camera preview, it just show me “Device response timeout, please check if your device is properly connected.”
Anybody meet the same question and give me some advice?
Hi there,
So which version of the BSP did you use?
3.0.3 or an older 2.0.11 may need a rollback.

I use version 2.0.17 esp32 by Espressif Systems and add the additional board manager url “https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json”. By the way, my arduino ide version is 2.3.2. Do I need to update it to the newest version 3.0.4? 
Hi there,
I would try 3.0.0 see if that builds and flashes, Should work. Check the demo thread on here , I have compiler output showing what I used when it worked.

Hi, I have tried to change the version to 3.0.0 but it seemed does’t work. I am not sure if it makes sense to change the board manager version in ide but upload public ai model in web sensecraft ai? The two don’t seem to be related?
Hi there,
So the issue is with the SenseCraft not the S3, (In the case of the camera for the sense it would). Not for senseCraft web site preview though. Clear the cookies and try again. You use a browser to upload and to preview. That is were you are having difficulties then? It was not clear to me what exactly was the result?
Just NO preview?
GL PJ
Yeah, you are right. I connect the s3 sense to computer, upload public model in brower and try to preview. Sorry for the unclear statement, I just have the authority to upload images. This is what I got when I try to invoke the preview. And I have just tried clearing the brower cookies, it just show the same error.
Hi there,
Ah’ Nice to see it… LOL
I have seen this b4, it was something related to the settings or browser link. It should work if I’m remembering correctly.
Have a LQQK at this XIAO ESP32S3 Sense camera not working - #8 by PJ_Glasso
does the web page for camera server work?
Just a long shot but still worth noting if it works.

Guys, I believe that the firmware that is installed on the ESP32S3 is ATFirmware, to work together with the Grove Vision AI V2. I used object detection on this board, but not via SenseCraft. There is a step-by-step guide by Marcelo Rovai on the Seeed wiki and also on Hackster.
Hi there,
What is the link to that web site?
is it been updated?

It’s the strangest thing. The web camera server can work, but the sensecraft preview does’t work. Though the color tones in the camera screen often take on a purplish hue and I didn’t know why either 
, but it does work.
Hi there,
Well now the hardware is verified. Something in the camera settings and be sure to remove the protective tape on the lens. LOL I wondered why out of the box what I had was blurry like heck. Then I saw the tape…
Also takes a lot of LIGHT on the subject I found.
In my opinion its a gimmick(this camera). That’s why the Grove vision 2 comes with the switchable camera capability is why I think that. I haven’t read anyone jumping up and down How great it is… So
Keep going you’ll get it figured out. I’m looking back to see where I read the web site issues , like yours with preview was a problem.

Hi, I have tried to combine the grove vision ai v2 with the s3 and use the example camera_web_server in Seeed Arduino SSCMA.
The compilation prompted successfully and also showed the ip address, but when I hit the start stream button, it just show me the two errors all the time.

Hi there,
So looks correct and proper IMO. nice work, so some obvious stuff , PSram is enabled in the tools menu on the compile of the S3 code?
something is not connecting, How does the solder joints look? no flaky ones.
I know this last thing is wack , but have you tried rebooting and starting the Sensecraft site first?
Stretching all the way there… Do it , get a beverage AND REBOOT.

Hi, I have just tried to upload a example code to output my recognition info to check if the whole connection is alright. And it showed the box info perfectly I think (I upload a face recognition model in my grove vision ai v2 using sensecraft) . So I went back to upload the web camera server code, it just showed me the same error. I have enableed PSRAM also, but I’m not sure the other settings are correct so I upload the full image. Reboot doesn’t work either. 
Hi there,
Appears to be correct AFAIK.
I’ll have to break out my box of stuff and see if I can reproduce , I have two of these Grove V2 units and a C3 and S3 with camera so time permitting I’ll give it a go.

I’m looking forward to your feedback.Thanks for your patience and time! 
So ,
when i connect to S3 it connects but never gives the option for preview,But if I switch to the V2 it connects and previews right away.

Probably need some other firmware on the S3 with camera to get that going.
WIP 
same in the other web site , training lets me preview the image from the V2 device no issues

Thank you for the info you have provided! Can you finally try connecting s3 and v2 together and turn on the web server? The code is camera_web_server in the Seeed_Arduino_SSCMA library. Thanks again.
