  My case (Fire version) does not allow me to reach the internal connector from the outside. I've ordered a grey "version".

  @lukasmaximus said in Button Unit Issue testing help please.: I have tested the blocks associated with the single button unit and they definitely need some work. Button press c shaped block only allows for a single press or release and the jigsaw shaped block when combined with an if condition it throws an error that btn0_wasReleased or wasPressed is not defined. These issues will be resolved in the next update and hopefully some extra functionality added. Yeh, I was getting the btn0 is not defined error.

  I've just taken several goes to write the firmware (I think my W7 laptop to blame). It kept getting stuck in bootloader mode and wouldn't leave. Finially got it to program and reset after pressing the on/off button twice.

  @mcbridejc Hi, We will put on sale a new product named "Bus" which is aimed for developers to expand I/O. And here's the difference between with all cores. Maybe help you. https://github.com/m5stack/M5-Schematic/blob/master/Core/hardware_diff_between_m5cores.md

  @watson No, there was no COM-Port. As if it is not plugged or turned wrong around. But as told, now it is ok. And i am glad it is. I like the M5s very much. I still think, the capacitor solved it. But of course i am not sure.

  iIRC I seam to remember something on one of the Esp32 forums with a similar issue. I think it was something to do with bus clock speed issue. I think it was down to the clock being set to high for the psram.

  @jpilarski said in issue with remote in 1.0.3: Nice work on the adc, iic, and on adding more unit blocks. Unfortunately it looks like there are issues with the remote blocks. They look to be overlapping on screen and make it difficult to properly select remote blocks. What web browser are you using to load UIFlow as it worked fine for me.

  @felix42eu said in Hardware Variantion and Firmware Compatibility: @ajb2k3: OK, I did not know that arduino was not fully supported. thanks. is m5go and m5fire a different product? I do not think so. where are the sources of the versions located if they are open source? or do you mean the binaries are free (I found them in the M5burner replease) The espressif idf is a topic which I have too look deeper into. All sources, documents and specs are found on github. Git Hub Some of the docs are a little out of date though. some of the "grove connection" units are found on the seeedstudio grove website.

  @lukasmaximus In your reply above you mentioned firmware 1.0.1 for the stick but in the M5-burner download it only has version 1.0 of the uiflow firmware for the M5stick. Can you please verfiy which firmware is the most recent. Also will the MPU9250 work with the M5stick in uiflow. thanks
