The Arduino IDE suggests an upgrade for the M5Stack board from 2.0.5-1.0 to 2.0.5+1.0. However the upgrade always fails with this message:

Cannot install platform: Installing platform m5stack:esp32@2.0.5+1.0: testing local archive integrity: Testing archive size: fetched archive size differs from size specified in index: 250363319 != 250355049

What is the problem here? Should I de-install the old board and then intall the new one, or would that create problems?

My regular browser is Chrome under Ubuntu 22.04 and it is the latest version 106.0.5249.103. When I launch the web version of UI Flow under Chrome I cannot read or save m5f files to my local hard drive. I have no problems in downloading files from other websites. I tried using Firefox to use the web version of UI Flow and it works perfectly, saving and reading files as expected. Both browsers show the UI Flow version to V1.10.8 though the top bar is slightly different in that the Chrome version has a "Save as" button but the Firefoxx version doesn't.

I have tried launching chrome with google-chrome --allow-file-access-from-files but still cannot access the local disk from the UI Flow website. I have tried altering the settings for flow.m5stack.com also without success.

This seems to be a UI Flow/Chrome issue, rather than a Ubuntu issue, because the site works perfectly in Firefox under the same OS and I have no problems downloading other stuff in Chrome. I hope someone can help me because it doesn't seem right that I should need a separate browser just for the website flow.m5stack.com

@ajb2k3 I am using Chrome version 106.0.5249.103, the latest version for my Ubuntu 22.0 OS. Maybe this is off topic but what Security and permissions tabs do I need to check to allow a website to read and write to my harddrive? I have tried adding "--allow-file-access-from-files" when launching google-chrome from the terminal, but that didn't work.

@steve1 I have just tried the UI Flow web application https://flow.m5stack.com/ in Firefox (I was using Chrome up until now) and I can save my work by clicking on the "Floppy" icon. So it seems this is a Chrome problem.

@holofloh Clicking on the Floppy doesn't do anything in my setup, no downloads to the downloads directory. By the way I am using Chrome under Ubuntu Linux.

I have given it a name in the bo top-right where the default is "Main" but I think you must mean something else. Would you be so kind as to walk me through building a program using Blockly and then saving it where I can reload it for further work another day.

I am more used to programming with the Arduino IDE and the UI-Flow web app does not seem intuative to me

I can connecr my M5Stack Fire and CoreInk to the web Ui Flow app and upload Blockly programs to the devices and run those programs on the devices. What I cannot do is save those programs to use again another day. Clicking on the "Save" or "Save as" does absolutely nothing. How can I save the apps I develop using blockly on the UI Flow Web app?

I recently bought an "M5Stack Ultrasonic Unit (RCWL-9600) Distance Sensor I2C Grove" and cannot get it to work at all. I have tens of M5Stack units and always start of by using the sample codes from the Wiki. Unfortuately neither the UI Flow code nor the Arduino code from the Wiki work in the case of the ultrasonic range finder. With the UI Flow code the sensor is recognized as being connected to I2C but delivers the distance of 7958.04mm and never changes. With the Arduino code the distance is always around the 500mm mark no matter how far away the obstruction is.

Do I have a faulty unit or are there known issues with this unit?

Thanks, but I still cannot read the Serial.read() from "porthub.hub_a_read_value(HUB_ADDR[2]);"
