If do you have difficult to update your code because the PC is away from controller or USB port is hard to reach follow this tutorial to see how to update the code using WiFi.


1 xNodeMCU V3;
1 x Logic level shifter 5 to 3.3 V;
1 x Switch 2 or 3 poles.




Watch on

After get some experience using AVRDUDESS you can try send the code directly from IDE but this way sometimes fails and it is hard to debug.

1 - Select Arduino as ISP:


2 - Upload using this option:


P.S For now is not possible use the NodeMCU as MQTT client and ISP programmer.

Enjoy. :)

WARNING: DO NOT try install the code using this method if do you haven't some experience with Arduino.
Please do not PM me for support unless it is absolutely necessary.

I'll not write custom function to nobody unless you can pay for my job.
