UART stands for Universal Asynchronous Reception and Transmission and is a simple communication protocol that allows the Arduino to communicate with serial devices.
Which special protocol is used in Arduino communication?
UART, which stands for Universal Asynchronous Reception and Transmission, is a simple serial communication protocol that allows the host (Arduino) to communicate with serial devices.
How to send data from an Arduino to an ESP8266?
When you open the ESPlorer IDE you should see a window similar to the preceding Figure, follow these instructions to send commands to your ESP8266: Then you simply click the button Save to ESP and save your file with the name “init.lua”. Everything that you need to worry about or change is highlighted in red box in the following Figure.
Which is an example of an ESP8266 network?
For example, you can have two boards communicating with each other. You can add more boards to this configuration and have something that looks like a network (all ESP8266 boards communicate with each other). In summary, ESP-NOW is ideal to build a network in which you can have several ESP8266 boards exchanging data with each other.
Is the ESP8266 NodeMCU the same as ESP32?
This video was recorded for the ESP32, but most concepts also apply to the ESP8266 NodeMCU board. Stating Espressif website, ESP-NOW is a “ protocol developed by Espressif, which enables multiple devices to communicate with one another without using Wi-Fi. The protocol is similar to the low-power 2.4GHz wireless connectivity (…) .
How to save Lua files to the ESP8266?
I recommend using the ESPlorer IDE which is a program created by 4refr0nt to create and save Lua files into your ESP8266. Follow these instructions to download and install ESPlorer: Open the ESPlorer (as shown in the Figure below). Copy and paste the code below into ESPlorer IDE window.
