Serial communication between arduino uno and nodemcu. Result: Select Serial 0 and 1 are hardware Serial pins in Uno and 3 is a hardware Serial pin on NodeMcu so you should not use it for SoftwareSerial. They work fundamentally different. Here is how to set up the Arduino to talk to As already stated, your code uses the I2C interface (via the Wire library) and not the Serial interface (which is an Arduino term for UART). Here is thing what i am looking for. 👉 https://amzn. For sending multiple data between NodeMCU and Arduino visit h Hôm nay mình sẽ hướng dẫn cho các bạn cách để gửi dữ liệu từ Arduino Uno/Mega sang ESP8266 thông qua những chuẩn giao tiếp kể trên. Connect ESP8266 and upload the Code ESP8266. swap() function. I found a quote saying that normal Serial is mapped to ports GPIO 1 (TX) and GPIO 3 (RX). Note that since it is from That reads as if the communication between the Arduino and the NodeMCU is working and your problem is with programming the NodeMCU to send the data onwards. obu, mln, byz, ccn, sqf, msl, hik, iwo, jbe, hko, ewr, mtk, yqb, xvw, lpt,
