      I've updated the post and the demo code inside it to show the fix of pulling up the CS pin on the LoRa board before initialising the screen to prevent the screen from staying white.

      Hello @HansDia95 using UIFlow firmware 1.9.8 on my M5Tough I can simply hide a button and after that it no longer is touchable until I make it show again. Have you tried Set touch_button_X hide block? Care to share your UIFlow code? Thanks Felix

      Thank you for this awesome tutorial. I've got my copper wire on order, and am looking forward to putting it together. =D Thanks to some brilliant recent inventions, there's now antenna analysers for $50, called "NanoVNA". You can use them to perfectly tune the J Pole antenna, so as much of the transmit power as possible leaves the antenna. https://www.youtube.com/watch?v=QJYeFpiqY8c

      Hello @brvus76 I don't really know why the communication might be slow. I can only guess that UIFlow firmware maybe has some safeguards in place to prevent serial from flooding the line. I guess that your software on the PC manipulates the control lines (CTS, etc.) on the serial port in a way which triggers the auto download / reset mechanism in M5Core2. Unless there is some setting in your software to configure that behavior I don't think there is much you can do. Thanks Felix

      There was a change to the way the power control chip in the cores and only some are able to programmatically control the chip.

      @felmue Thanks! So then I can add an external speaker or stick a wire on it and use that as the antenna of an AM transmitter ;) like in this video: https://www.youtube.com/watch?v=lRXHd3HNzEo

      R

      Gpio 36 don't have any internal pullup, so code generated in uiflow may fail and throw error (try to set non existing internall pullup or pulldown). You should connect to device by serial terminal and observe the messages. You also should use a resistor with values in kilo ohms eg. 4.7kohm or 10kohm esp32 pinout reference: https://randomnerdtutorials.com/esp32-pinout-reference-gpios/

      @teiafra Great tip! I always forget about the resource manager. That is another way to remove apps from the device.

      @ruvic101 use the last version firmware. (you could find it in this page :https://docs.m5stack.com/#/en/quick_start/m5stickv/m5stickv_quick_start) also , for the time being the yolov3 function is unstable . even you loading success the model and runing. It may still happend memory not enough
