How do I connect NodeMCU to another NodeMCU?

How do I connect NodeMCU to another NodeMCU?

1. Run an additional Arduino IDE.
2. Open the “wifi_client_01. ino”.
3. Replace the asterisks “****” with the SSID and the password of your home WiFi router.
4. Put the IP address of your server into the 15th row.
5. Upload the program.
6. Run the serial monitor for the new Arduino IDE also.

How do you communicate with 2 ESP8266?

Can ESP8266 talk to each other?

Making two ESP8266 talk each other is an easy task for this powerful devices and with a bit imagination you can do impressive projects with low budget.

Can NodeMCU act as hotspot?

You can use WiFi with the NodeMCU (ESP8266) even without a WiFi router. All you need to do is create a NodeMCU WiFi Access Point and the device will now act as a WiFi gateway.

How do I transfer data from NodeMCU to local server?

1. Open your web browser and type localhost/esp8266.
2. Open the serial monitor of your arduino and set the baud rate to 115200.
3. The wifi ssid and ip address should display to the serial monitor.
4. You should get a response 200 from the server and ok message.

How to establish two way communication between ESP8266 NodeMCU?

Learn how to establish a two-way communication between two ESP8266 NodeMCU boards using ESP-NOW communication protocol. As an example, two ESP8266 boards will exchange DHT sensor readings. We’ll use Arduino IDE. We have other tutorials about ESP-NOW with the ESP8266:

How does wireless communication between Arduino and NodeMCU work?

Wireless Communication between Arduino and NodeMCU using NRF24L01 Transceiver Module RF communication is one of the most used communication technique in IoT applications, and we previously used 433 MHz RF modules in communication between two Arduino.

How is the NodeMCU connected to the transmitter?

In the Transmitter side, the NodeMCU is module is connected to a NRF24L01 module which acts as the Transmitter. As shown in the figure the SPI Pins of the NodeMCU are connected to the SPI pins of the NRF24L01 module.

Can a Raspberry Pi work with a NodeMCU?

Using MQTT, NodeMCU, DHT22, RaspberryPi and IoT MQTT Panel to monitor temperature and humidity. Using a Raspberry Pi 3 B+ as a broker for several NodeMCU with DHT-22 sensors measuring temperature and humidity and monitor on IoT MQTT Panel App. I made the algorithm for NodeMCU and Raspberry escalable.
