Have you tried erasing the flash, and reflashing a different firmware? Did you use the firmware burner in uiflow desktop to burn the firmware?

This is something I also find quite bizarre, and is an issue with the new M5Atom also.
the address should be 0x68 but on using the i2c scan program on m5atom which also has an mpu6886 no addresses are found. then I found this in the arduino header file which puzzles me.

void setup()
{
    M5.begin(true, false, true);

    if (M5.IMU.Init() != 0)
        IMU6886Flag = false;
    else
        IMU6886Flag = true;
}

why should it's address be zero. It seems like this code works in arduino in the case of the M5Atom but I cannot find a workaround for micropython.

let me test with mine and get back to you

I was informed that the red pcb is the older version. Black version fixed some issues. Would like to know what issues you have had with them. I cannot seem to use mine with any hat, It just forces the stick to switch off

A few other tips. If you want to transfer files to the flash of the device press ctrl + a + \ to kill the terminal session and processes running, this will allow you to now transfer files using ampy, personally I prefer upyloader now as its much more convenient. Also when your finished with your terminal session press ctrl + a + d to detach the device, this will help to avoid the "pty not found" message when trying to start a new terminal session or any issues with using uiflow over serial after closing a terminal session

Hi @AP1290 Sorry to hear that you were having these issues. I believe I should be able to help you with most of these issues.

1. Due to the nature of how the UiFlow software is developed for MAC, it requires that you place the uiflow app into the applications folder. Only then will the firmware function work.
   You may still have issues with burning the firmware to the StickC though as I have. I tend to prefer using esptool to burn the firmware https://github.com/espressif/esptool as I find it's much more stable.

2. There are known issues with 1.4.4 and 1.4.3 which haven't been fixed yet due to staff being away on chinese new year holiday. Best to wait a while and I recommend using 1.4.2 for the best results.

3. I am not familiar with MPFshell I tend to use the standard screen terminal on mac, first finding the port with ls /dev/tty.* and then starting a terminal session with screen /dev/tty.usbserial-xxxxxxxx 115200 you need to make sure uiflow is closed or any other program which is trying to access the device over serial. If the issue persists, try unplugging and reinserting again or switch to another usb cable

Hope that helps, let me know if it works for you

This is possible also with esp-now, I've even seen it done with uiflow but haven't tried personally
