UNITCAM Problem
-
I am using the example code straight out of UIflow and only adding my SSID and password , but I get no qrcode.
-
- check your device's connection is not a problem.
- if using the UART mode is works, you should check to enter SSID and password are right. (don't include any special char)
- which UIFlow firmware version are you used? after you run the program. did you get any errors?
-
I believe you that it works on your intranet but I live in Germany and it doesn't work there.
To your questions-
my device has no problem
-
my SSID and password are correct and there are no special characters in them.
-
why the question about the UIFlow version when it should only be possible with version V1.7.8?

@m5stack Same here. I have checked and double checked my SSID and password. The uart works and I can see the picture on the display. I am using 1.7.8 on both the UIflow and the Grey Core. I do not see any errors, but I can't help but thinking it is freezing up. Sometimes it will display pictures by a frame every 5 seconds, but sometimes it does not. But more than anything it does not seem to be retrieving the qrcode.

@m5stack Ok, I finally got it to generate a qrcode. Maybe what the issue is, is that it takes an inordinate amount of time to generate the qrcode. It does not immediately generate the code. It seems to take about 3-5 minutes to generate the code. I was thinking it was maybe instantaneous. Maybe that is the issue with others too. The issue I am having now is that I do not see an image. I see the image using UART, but I'm not seeing it on the web address.
-
@m5stack Sorry for the multiple replies. An update. I moved the core and camera very close to the router and it immediately connected and produced a qrcode and I am able to see the pictures.
-
also with me it works now without that I have changed something
-
@m5stack I don't know why but it finally worked after several runs from the UIFlow. I didn't change anything, but it seems to be quite sensitive to the WiFi connectivity. Now I can see interval images on the camera.m5stack.com/timer-cam/...
-
@nigauriko maybe is the wifi signal quality not good?
-
Just wanted to check in and see if anyone's UNIT CAM is working with the current version of UIFlow. I'm beginning to think I've killed mine somehow. I can't get it to work in UART or WIFI mode either one, I've tried it with a couple of Cores and nothing works.
Thanks!

@m5stack I'm having this same problem. I think it is probably caused by a slow Wi-Fi throughput issue with UnitCam.
A solution to this problem has been found by Sohtamei in the following thread;
https://community.m5stack.com/topic/3649/unitcam-hw-issue-cannot-stream-video/8
On the UnitCam, set the WROOM-32 clock to XCLK=8MHz and the ov2640 clock to twice the current clock.
Could you please reflect this solution in the UnitCamForUIFlow firmware? -
@m5stack
Could you please correct the UnitCamForUIFlow firmware as follows?
Set the WROOM-32 clock to XCLK=8MHz and the ov2640 clock to twice the current clock.This solution has been found by Sohtamei in the following thread;
