Thank you for the help. That was all it was. I fired it back up again and issues commands from the correct command set and it seems to be working. Now to try it out more.
I just got my COM.X modules in the mail. I was looking forward to playing around with these and maybe creating a point to point network of sorts. Just to play with, maybe transmit weather data. I don't seem to get any response with the module though. I was following the M5Stack Tutorial with the Grey Core. I have everything as shown in the picture in the tutorial as far as RX/TX pins. I get no response at all in the M5 Burner, but if I open the serial monitor in the Arduino IDE, I get the following ERROR. Any ideas where to start? Do I need to register this with the TTN or set the frequency or something? Also, I can't help but think the pins on the module are slightly too short and may not be getting a good connection.
@liemph I just checked mine using a Fire and it seemed to work. What Core are you using? Maybe that's it or maybe..Just last night somehow I selected the M5 Paper when I was working on the M5 Ink. Maybe just double check you have the right core selected. Maybe it's not supported with the core you have selected by accident? Maybe it's worth looking. Sorry about all the "maybes"
I hope it's just a bug or it's an accident. I have the baseX too.
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.
@world101 Thank you! I think I was sniffing all around it last night, but I think I had a conflict with the display. I was trying to transfer it from one Core to another via UART. I learned something new doing that, so it wasn't a total loss. This is very helpful.
@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.
