How do I send data to cloud using ESP8266 WiFi module?

To accomplish this, follow these steps:

1. We will connect the ESP8266 to a local Wi-Fi network that has an active Internet connection.
2. Once the connection is successful, we will send a GET request to the cloud server and then display the reply that the server sends back to the ESP8266 board:
3. Enter the SSID and password :

How do I send data to 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:

1. Connect your FTDI programmer to your computer.
2. Set bad raute as 9600.
3. Select your FTDI programmer port (COM3, for example)
4. Press Open/Close.
5. Select NodeMCU+MicroPtyhon tab.

Can Arduino send data over WiFi?

HTTP protocol and HTML language have made it possible to transfer the Data anywhere in the world, over the web. We have already covered some projects which use Wi-Fi with Arduino, have a look at them to Getting started : Sending Email using Arduino and ESP8266 WiFi Module.

Can Arduino send data?

The Arduino IDE (described in Recipe 1.3) provides a Serial Monitor (shown in Figure 4-1) to display serial data received by Arduino. You can also send data from the Serial Monitor to Arduino by entering text in the text box to the left of the Send button.

How do you communicate two ESP8266 WIFI modules?

Following are the easy steps to create two-way communication between two ESP8266 modules using Arduino IDE.

1. We will begin with Installing the ESP8266 support for the Arduino.
2. Making an ESP8266 module the access point(hotspot)
3. Making another ESP8266 module the station point(Wifi)

How do I transfer data from Arduino Uno to cloud?

Connect an Arduino to the IoT cloud using JSON and MQTT

1. read in analog data (in this project we’ll use a light level detector)
2. connect to an MQTT broker in the cloud.
3. publish data in the form of a JSON object to the MQTT broker.
4. view the light-level data on an Assetwolf portal.

How can I send data from Arduino to Android app through WiFi?

Connect the Arduino board to the internet. Either use an Ethernet Shield or a Wi-Fi chip or a GSM/GPRS module. Once connected to the internet, the value has to be posted to an IoT Cloud device channel. The last step can be executed in two different ways: Either have the Android App connect to the same I.

How do I connect an ESP8266 to Arduino?

By connecting ESP8266 to Arduino by using sofrware serial library and program Arduino to transmit your commands that you sent via serial port to ESP8266 by using software serial,you can drive esp8266 by sending AT Commands over serial monitor on your PC. So then you can connect to a server and send data by using AT Commands.

How to disconnect ESP8266 from the Wi-Fi network?

Now we need to disconnect our Wi-Fi module from the previously connected Wi-Fi network, by using the command AT+CWQAP, as ESP8266 is default auto connected with any previously available Wi-Fi network 4. After that, user can Reset the module with AT+RST command.

How to send commands to ESP8266 from esplorer?

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”.

How to allow serial communication on other pins of Arduino?

By using Software Serial Library here, we have allowed serial communication on pin 2 and 3, and made them Rx and Tx respectively. By default Pin 0 and 1 of Arduino are used for serial communication but by using SoftwareSerial library, we can allow serial communication on other digital pins of the Arduino.
