ESP32 Forum

Hi,

I know this is not ESP specific but maybe someone has experienced the same issue and can help. I have done some searching to see if there are reports of a similar problem but have not found any links.
My Windows 10 updated last night and now make monitor and make simple_monitor are not working.
Running make monitor I get the following:
$ make monitor
MONITOR
--- idf_monitor on COM7 115200 ---
--- Quit: Ctrl+] | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H ---

)

and running make simple_monitor I get the following:

Thanks for the update, Charles. In my testing the second write always succeeded, but seems that's not strictly the case. I've reopened the issue on Github, and we'll update the monitor again.
