Hello all!
I just received a Wemos (or clone?) D1 mini, and succesfully connected to a Win10 Usb, got a serial device, and installed the required add-ons on the arduino ide (I know good enough Arduino). With the Arduino's serial monitor I succesfully "conversed" with the Wemos with some "AT" command. So I tried to load the classic blink sketch, and it works. Now the ESP it's blinking... but the question is... how can now regain attention from the ESP so i can again talk to him through the serial monitor?

He is blinking, blinking, blinking, but the serial monitor it's dead and any AT command is ignored!

THANKS!

When you loaded the blink sketch you TOTALLY replaced the AT firmware.

You need to reload the AT firmware. How? See here http://www.xess.com/blog/esp8266-reflash/

I am not sure what the is latest version of the AT firmware. Perhaps some will post a link.
