Simple test of serial conection between 2 NodeMCUs, using SoftwareSerial and Arduino IDE.

This is a test of how two NodeMCUs can comunicate trough SerialSoftware, using Arduino IDE.


1) Get two NodeMCUs

2) Conect pin D7 (RX)  of NodeMCU A with pin D8 (TX) of NodeMCU B.

3) Conect pin D8 (TX)  of NodeMCU A with pin D7 (RX) of NodeMCU B.

4) Conect GND pin of NodeMCU A with GND pin of NodeMCU B.
