@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.

@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.

@world101 I couldn't get it to work with the Universal G code sender. It was like it could tell it was there, but it didn't seem to communicate. I think there's a lot to do with it all being ESP32 based or that you're going through a computer through the esp32 to the grbl module...I'm not sure. there is a I've not gotten any further along with it. I pretty much put it to the side and had hoped to come back to it. I think you could read line by line from a file on the SD card and write it to the GRBL module. So on my Shapeoko cnc router I can use the command $$ to see the parameters and settings and change many variables to setup a machine as you need it set. I do not see how you can do that with this device. Maybe in the arduino environment you can you the serial monitor. I was really disappointed that there is no documentation for this and I have found very little online.

I did find this, but I just didn't have the time to go down this rabbit hole. link text

@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.

I am using the example code straight out of UIflow and only adding my SSID and password , but I get no qrcode.

@m5stack How would you see the serial print log?

Same Here, I can't get the QR code either.

@ciconde
I agree. I had posted a similar request for the Paper. I would really like to be able to design multiple screens for it.

It sure would be nice to have a little more documentation for this module. Seems useful.

This seems to be pretty common. Not all modules are compatible with all cores. I wish they would advertise which modules work with which cores.
