Such functionality is provided by the NodeMCU enduser setup module. Once done ESP is switched to the station mode and can connect to the target WiFi. Then we are able to provide credentials to the target network. The module first boots in soft-AP mode, so we can connect to it using a laptop or a mobile phone.

This is when SSID and password to such network is not known upfront. The soft-AP mode is often used and an intermediate step before connecting ESP to a WiFi in a station mode. The maximum number of stations connected to the soft-AP is five. Such mode of operation is called soft access point (soft-AP). ESP8266 can provide similar functionality except it does not have interface to a wired network. Station (STA) mode is used to get the ESP8266 connected to a WiFi network established by an access point.Īn access point (AP) is a device that provides access to Wi-Fi network to other devices (stations) and connects them further to a wired network. This offers the possibility of building e.g. Third, ESP8266 is also able to operate both in station and soft access point mode at the same time. Therefore, we can connect other stations to such modules. It can also operate as a soft access point (soft-AP), to establish its own WiFi network. Each access point is recognized by a SSID ( Service Set IDentifier), that essentially is the name of network you select when connecting a device (station) to the WiFi.Įach ESP8266 module can operate as a station, so we can connect it to the WiFi network. An access point is usually integrated with a router to provide access from Wi-Fi network to the internet. The access point on the other end is connected to a wired network. Connection to Wi-Fi is provided by an access point (AP), that acts as a hub for one or more stations.

To avoid these potential crashes, it is advised that the WiFi subsystem be suspended with wifi.suspend() prior to the execution of any tasks or functions that exceed this 15ms guideline. Any function or task that takes longer than 15ms (milliseconds) may cause the WiFi subsystem to crash. The WiFi subsystem is maintained by background tasks that must run periodically. enduser setup / captive portal / WiFi manager.
