I am using NodeMCU 1.0 and my based firmware is ESP8266_NONOS_SDK_V2.0.0 (http://bbs.espressif.com/viewforum.php?f=46)
I develop my application firmware with Arduino IDE and it was working on power cycle.
(I can connect to my WiFi after power off).
And then, this issue is just happen with no signing ( I believe is happen after I play around with the GPIOs pin)
My NodeMCU just no longer can detect WiFi after power off ( For Reset is still Fine),
is just look like my ESP8266_NONOS_SDK_V2.0.0 be vanish.
I was search around the topics relate to this issue
wiki/doku.php?id=esp8266_gpio_pin_allocations
The topics descibe my NodeMCU boot into upload mode after power off, the GPIO0 has to pull high in order to enter Normal Mode
I tried and it work once, but no longer work after that. And then, I tried all the possible connection of GPIO 0 , 2 , 15 but still cannot boot my NodeMCU into Normal Mode after power off.
Due to espressif firmware is supporting AT command, I tried connect my WiFi with AT command and it can reconnect after power off, but just not for the Arduino. (Look like my espressif firmware be wiped after I upload my Arduino code)
Before that my NodeMCU was working even that I didn't pull the GPIO0 to high, now no matter what I do also cannot bring back it to work.
Might I ask what happen to this case? it is possible that I spoiled my NodeMCU?
