- Wed Apr 08, 2015 5:01 pm #13917 I just end up in the wierd situation. I was working on improvement to my simple program and suddenly my module stopped working, and does not respond for any command.. but if I try to flash it everything seems to be working and I'm able to finish flashing. That's it - no command after flashing.

If I connect another module it seems to be working fine.

Any idea what might happen ?

- Thu Apr 09, 2015 12:47 am #13929 For flashing GPIO0 is connected to ground - and it's working fine. I'm able to flash it.

After this GPIO0 is disconnected and this is the part when chip does not respond.
Yes it was working before.
