This recipe will show you how to configure the access point (AP) mode on the ESP8266. Once configured, the board will become a Wi-Fi AP, and you can connect laptops and phones directly to the board using a standard Wi-Fi connection.
Wi-Fi is so ubiquitous that this feature becomes a very powerful way to offer connectivity. You can use the technique shown in this recipe to incorporate Wi-Fi AP functionality into your own projects. This lets you establish wireless connections between your board and a phone or laptop, even when there are no other access points available.
