ESP8266 Community Forum

- Thu Mar 19, 2015 9:42 am #12256 Hi!

I just received my ESP8266-01 that I successfully flashed with NodeMCU firmware programmer. I was then able to communicate with it using a serial connection. But I accidentally touched the GPIO2 and RST pin: the blue LED then blinked. And I couldn't communicate with it anymore.
So I reflashed NodeMCU with success but again, I can do nothing with the serial.

Do you know what can I do to solve that? That's pretty weird, I cannot communicate with it but the flashing does work. So I don't think I burned the ESP8266...

Thanks for your precious help.

I don't know if I touch 2 pins but I have the same pb.
It seems I can flash, but no response.
