How can an ESP8266 be connected to an existing network?
The ESP8266 can communicate over WiFi in two different modes. You can connect to an existing wireless access point, or hotspot, similar to the way you connect your phone or computer to the Internet. This is called “station” mode.
Why is the NodeMCU not connecting to Wi-Fi?
If the ESP8266 still does not connect to Wi-Fi, you need to check and change the settings of the router or modem. Then choose the 802.11G+N option in the operation mode. Once the operation mode is changed, it also modifies the automatic configuration of the channel.
What is NodeMCU and how does it work?
NodeMCU is an open source firmware for which open source prototyping board layouts are available. The firmware uses the Lua scripting language. The firmware is based on the eLua project and is based on the Espressif Non-OS SDK for ESP8266. It uses many open source projects, such as lua-cjson and SPIFFS.
