Small size and low cost makes it suitable for sensor nodes. The objective of this post is to explain how to connect the ESP8266 to a Flask Webserver and send a HTTP GET Request. Right-click in the query window, and then select Connection > Change connection. It is open source on github. In this project, we will connect a push button switch with NodeMCU. But,I want to do that using C# form application. In 'port from' and 'port to' mention the port that has to be forwarded to NodeMCU (Ex: 80 - 80). NodeMCU - Set up Arduino IDE and Start using WiFi. See the 'mqtt_reconnect_nonblocking' example for how to achieve the same result without blocking the main loop. When ESP8266 hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. We'll stay tuned until we get a response from the server (You are alive!). createServer(port, handler(req, res)) Parameters¶ port: Port number for HTTP server. My goal is to embed the NodeMCU (ESP-12) module in an antenna (or any other thing) to be remote controlled over my home network. There are two architecture which are described in the video. On sensor board, you can find two potentiometers. It allows you to program the ESP8266 WiFi module with the simple and powerful LUA programming language or Arduino IDE. This action changes only the server that the query window is connected to, not the server that Object Explorer uses. For the last part I used the NodeMCU board because it has a build in LED and a button. In this project, we will connect a push button switch with NodeMCU. The idea is pretty simple: do a temperature conversion, connect to a wireless network, transmit the reading to a server, maybe get back some configuration and start over. The following connects your NodeMCU ESP8266 to AWS IoT server then: - publishes "hello world" to the topic "outTopic" every two seconds to the server. Connect a wire from your ESP8266 reset pin to GND Remove that wire from GND and connect to VCC Repeat steps 2 and 3 a few times until your ESP reboots and hopefully the NodeMCU flasher can detect your ESP and start the flashing process. NodeMCU requests the data from the Arduino by sending a character. 0(ESP12E module)”. i want the data of the 2 nodemcu to be posted on one server. Currently I have some NodeMCU laying around and a friend showed me how to connect to the Azure IoT Platform using the Azure IoT for C SDK.
