Because these packets are unencrypted, you just need the mac address of the WiFi router and of the client device which you want to disconnect from the network. You don’t need to be in the network or know the p
Connecting your shiny new ESP8266 to WiFi can be as simple or as complicated as you please. Most people decide to manually add it. Some people find clever ways to make the bloody thing connect itself. [Eduardo Zola]transfers his WiFi password using the flashing light of a smartphone screen...
Posted byDP July 6, 2016 2 Comments on ESP8266 NodeMCU Backdoor uPWM hack for IR signals The AnalysIR crew has published an article showing how to achieve accurate PWM for Infrared carrier signals on the ESP8266 NodeMCU: Quite simple really – just set the baud rate to 10 times the desi...
Configuring WiFi with WiFi manager Note:The WiFi manager only works on ESP32. For ESP8266,WIFI_SSIDandWIFI_PASSWORDneed to be provided insecrets.h. This project usestzapu's WiFiManager. After booting up, the device will try to connect to known access points. If no known access point is ...
The parts list for this game, which [Roman] calls the ToggleBoss, is about as short as it gets. There’s a NodeMCU ESP8266 development board, a common SH1106 OLED display, and a trio of suitably clunky toggle switches. Add a bit of wire, toss it all into a 3D printed enclosure, ...
This article will focus on applying AES encryption and hash authorization functions to the MQTT protocol using the popular ESP8266 chip running NodeMCU firmware. Our purpose is not to provide a copy/paste panacea, but to go through the process step by step, identifying challenges and solutions al...
station_cfg.pwd="Your Password" station_cfg.save=true wifi.sta.config(station_cfg) Connecting to a server with WebSockets is easy, but since we’re not using HTTP, we’ll have to remove thehttps://and replace that withws://. (Note: notwss://because we’ve not enabled encryption yet...
Besides the notification system, the device itself is based on a NodeMCU/ESP8266, communicating over WiFi, and is a simple push-button design which coffee drinkers push when a fresh pot is made, and then push again when the coffee is empty. While relatively straightforward, this project is ...
To conclude: the trick with using deep sleep on the ESP8266 when running NodeMCU is to write your code so that it does the right thing on reset, and stores any long-run data somewhere. And don’t forget to connect thewakepin to theresetpin — the chip will stay asleep until you puls...
All of the LEDs are connected to a NodeMCU ESP8266 by way of a 74AHCT125 level-shifter, though [Will] notes you could certainly use a different microcontroller with some tweaks to the code. As it stands, the user selects from various lighting patterns using two potentiometers and a butto...
