A quick example of a simple WiFi application using the WiFi and network-socket APIs that is provided as a part of mbed-os.

The program brings up the WiFi and the underlying network interface, and uses it to scans available networks, connects to a network, prints interface and connection details and performs simple HTTP operation.

Supported hardware:

Not that the mbed target board the WiFi shield gets connected to shouldn't have any other network interface e.g. Ethernet.

ESP8266 is a fallback option and will be used if the build is for unsupported platform.
