User can connect to nodemcu esp8266 and access the web page. ESP8266 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. When push button is released, a "not pressed" message will be sent to remote client. The "Station" mode allows Nodemcu to connect to local WiFi (as a client) whereas "AP" mode allows connect to Nodemcu directly. - Sun Sep 08, 2019 1:31 pm #83710 I am trying to connect my nodemcu client with nodemcu server, while my client is connected with two sensors (DHT11 and Soil Moisture) and it is workign perfectly, but on the server side I am unable to get all values, it is only giving me value of one parameter. Third, we create a script in Rpi ,upload the required code in NodeMCU and run the python script to control leds from both server and client side. LED is useful to show some status beside transferring the data while for the button I planed very important function to start (and stop) my server. each data is on a new ip address. The Bug is Interrupt was not working after 40-50 minutes of continues operation. Introduction Internet of Things (IoT) provide the ability to connect a large number of things or devices via internet. We can do this by first opening the serial port on the Arduino IDE and identifying the IP address of the NodeMCU ESP8266 WiFi server.
