@electrik I did not. Thank you for pointing me in that direction!

Good Morning,

I have just tried compiling the nodemcu MQTT gateway, and I receive a compile error when I verify the sketch. This happens on two PC's i have access to.

Board options I have tried are:
Board - NodeMCU 1.0 (esp-12E module)
Upload speed - 115200 also tried with 9600
flash size - Tried all 3 options
IwIP variant - Tried all 4 options

I'm not really sure what I am looking at. Is there anything I can try?

The error is:

Arduino: 1.8.7 (Windows 10), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Flash, 4M (3M SPIFFS), v1.4 Higher Bandwidth, Disabled, None, Only Sketch, 9600"

Build options changed, rebuilding all
