i could ony find node mcu but, it still says this:

Can you send me a link to your module?

I have the same problem but I'm using this ESP module: https://www.google.dk/search?q=esp8266&client=ubuntu&hs=SqO&channel=fs&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiG2pyvwuLTAhXnZpoKHes9CvoQ_AUICigB&biw=1920&bih=1110#imgrc=Z2zdlsmWCMB6rM:

And I have installed many versions of ESP board packages but non of them worked, so now I have the latest one 2.3.0-rc2 and I can see that it is the only folder in the path: C:\Users\Mypc\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266

I have also tried to swap RX and Tx and back again, it didn't made any changes :(
How can I solve this ?

Hi all, What is the problem with this code?

have you selected the correct dev board ? looks like it's compiling for atmega328. Project supports only ESP8266 modules

I am using A4988 stepper motor module.

from arduino-esp8266-alexa-multiple-wemo-switch.

I am trying to see whether my nema 17 stepper motor works or?
I have nano arduino, a4988 motor driver module and nema17.
do you have any works about it?

attention : MPU6050 library ''. 'Uncategorized" know is a fault I have
