  @ajb2k3 Well, this had nothing to do with the OS this time. But yeah, Ive had my own code, compiled as an EXE, promptly quarantined by the over-zealous anti-malware system. My employer takes security...very very seriously. To the point where software guys like myself get frustrated over things like this. But still, it was unnerving to be contacted by our cybersecurity team on the other side of the planet, telling me I'd set off alarms from several thousands of kilometers away, just from playing with my new m5stack devices I'd received that day, and that I'd have to have my machine scrubbed. But it looks like nothing has come of it, and was a false alarm. I'll just stick to using them at home instead of at work. I could never get M5burner to work through the layers of security anyway. BTW, Ive succeeded in geting both UIFlow1 and UIFlow2 working on my Core2 AWS. I basically bought it to use with UIFlow1 until UIFlow2 is more complete. Now I can use all my "only supported by UIFlow1" bits, while UIFlow2 grows.

  Does your mobile phone or tablet show a new wifi station that you can access? Edit: change the dropdown box from station to acc-point then try again. if you run a wifi scan on a device you will now find a new esp device.

  Hello @ratchapolp please see note here: Note: When using with the Core2, the base needs to be removed in order to burn the program properly. This has been discussed in this thread as well. Thanks Felix

  Slow response could be down to having the wrong baud speed set. UIFlow is built on Micropython and so does support multi files like arduino. Checkout Micropython. Org Esp is not like the arduino as instead of having functions permanently assigned to a pin, the esp using a matrix to assign functions to pins

  hey ajb2k3, I have python 3.10 and MaxOS monterey 12.6.1. When i click on the Erase, it get the error in the screenshot or the 3 dots indicating a process is in progress but the process loops indefinitely. Not sure what process is looping but it seems M5burner is trying to connect to the com port of the Core 2 but never gets a response. might be an OS bug as I swapped over to a windows laptop and i was able to download the image but after hard resetting the usb c to stay up - article here I have a working Core 2 again - happy user :-)

  What revision are you using as my AWS works fine. Have you tried using M5Burner to erase and rewrite the firmware

  M5Core2 AWS with COM.X Zigbee Module

  Hello @earthphisek I do not have the COM.X Zigbee module so I cannot test this myself. However with the following modifications the M5Stack example should work with an M5Core2 too. Replace #define <M5Stack.h> with #define <M5Core2.h>. Replace Serial2.begin(38400, SERIAL_8N1, 16, 17); with Serial2.begin(38400, SERIAL_8N1, 13, 14);. Hardware: in the COM.X Zigbee module set the two dip switches 16 and 17 to on and leave the other four in off position. Explanation: On the M5Core2 GPIO16 and GPIO17 have been replaced with GPIO13 and GPIO14. But the labeling in most modules still follow the numbering used with M5Stack devices. Thanks Felix

  Felix, It worked! Thank You so much! I thought I made the most expensive Lego brick in the world! HA HA. In all my years playing with the UNO I never found a way of shutting down through code. If I did I might of given up on IOT. Thanks, Trent

  @felmue thanks for letting me know. It’s been stable for the testing but I’m yet to move beyond. I tried looking at provisioning for vets and codes but my brain is not taking it in hence the low level MP stuff. I’m sure there will s an issue with MP but I don’t deal directly and not getting feedback from @m5stack or @IAMLIUBO

  Hello @university123 could you post your code? Using UiFlow I've put together a simple program which reads the touch state and x and y coordinates of the MPU6886 in a loop just fine and I do not encounter any lockup when I touch the screen. See below: from m5stack import * from m5stack_ui import * from uiflow import * from m5stack import touch import imu screen = M5Screen() screen.clean_screen() screen.set_screen_bg_color(0xFFFFFF) imu0 = imu.IMU() label0 = M5Label('Text', x=24, y=24, color=0x000, font=FONT_MONT_26, parent=None) label1 = M5Label('Text', x=23, y=86, color=0x000, font=FONT_MONT_26, parent=None) label2 = M5Label('Text', x=151, y=86, color=0x000, font=FONT_MONT_26, parent=None) while True: label0.set_text(str(touch.status())) label1.set_text(str(imu0.ypr[1])) label2.set_text(str(imu0.ypr[2])) wait_ms(2) Thanks Felix

  Your connection to your WiFi network with a password requirement is encrypted. Connection to AWS is also encrypted as AWS IoT does not support unauthenticated connections.
