Methods

init()

• Call this method to initialize before any function in this project

scanAsync()

• Get ssid and signal intense of nearby APs. Note that this api won't wait the response of Wi-Fi adapter

scanSync()

• Get ssid and signal intense of nearby APs. Note that this api will wait the response of Wi-Fi adapter

connect()

• To connect selected AP
  • resolve if connect command is executed successfully

let ap = {
    ssid: "your_ap_ssid",
    password: "your_ap_password" | NULL
}
let wifi_interface_name = "Wi-Fi"
wifi_native.connect(ap, wifi_interface_name)
    .then(() => {
        console.log("connection success");
    })
    .catch(() => {
        console.log("connection failed");
    });

disconnect()

• To disconnect the connection between AP and certain Wi-Fi interface

wifi_native.disconnect(wifi_interface_name)
    .then(() => {
        console.log("disconnected")
    })
    .catch(() => {
        console.log("failed")
    })

getNetworkList()

• get APs which is detected last time

wifiNative.getNetworkList()
    .then((list) => {
        console.log(list);
    })
    .catch(() => {
        console.log("getting list failed");
    })

getIfaceState()

• get information of Wi-Fi interfaces

let info = wlanNative.getIfaceStateNative()

• output
