Adding investigation, this seems to happen only if you upload to the core2 an empty project.

1.7.2 uiflow menu speed (core2)
The Core2 uiflow 1.7.2 firmware has following problem:
Description: The menu for ui flow on the m5core2 (the one to switch applications or go into setup) Its speed is too fast, making it imposible to make a selection on time.
Expected behavior: The time before uiflow starts running the selected mode should take longer so the user can make a selection.
Tested Hardware: M5stack Core2 for AWS, with defaul base.
RE: Core2 Esptool.py flash fail
I do not think you have a defective unit.
The thing is that uiflow is kept running in loops and when you try to flash with estool, or connect with rshell that unit does it in pauses. The same thing happens if you connect to a StickC (uiflow loaded) with rshell.
If you flash a generic Micropython and then try to flash again with esptool this should not happen as Micropython with out running any heavy app is not interrupting.
RE: AWS Edukit as normal Core2 for Uiflow
Hi! I flashed mine with uiflow and then micropython, all worked.
Core2 for AWS is just a normal Core2 but wth the base for AWS that also works perfectly with uiflow. I can control the leds and everything. the only difference with the other Core2 is the color and the base for AWS witch has a secure "element" that you can use or not use.
RE: M5 StickC Plus - How to access Bluetooth with UIFlow ?
StickC/Plus do not have BLE option because of the limitations, remember your are loading a big chunk of code called uiflow into it, and besides that you are trying to add BLE.
All this is accessible directly by Micropython code directly. It is not that the StickC/Plus can not do it. It can, is just that the BLE libraries are not included in the StickC/Plus firmware.
RE: Enable "back button" or "cancel button" in UIFlow main menu on device
The problem i think is that last uiflow mode selection is too quick and does not wait enough for the menu to make a change. I liked how on the StickC, you coul press button B and reset. that way you could force to change mode option.
Hope they fix this. it is just matter of adding time to the menu or as you said a cancel or back option.
