Hi @m5stack
you could pip install a pyserial module to solve it.
I tried that but the problem persists. As a quick fix, I just flashed it using a window virtual machine.
the LED always RED? which program are you use?
Yes, but after I flashed the new firmware everything is behaving well.
which program are you use?
It turned RED, after I tried to flash it with the newer esptool (2.8) as I showed in my initial topic
we will fix this bug in next version.
🤞🏻
Have a nice day
