Angular#

import { WifiWizard2 } from '@ionic-native/wifi-wizard-2/ngx';
constructor(private wifiWizard2: WifiWizard2) { }
# Global Functions
These are functions that can be used by both Android and iOS applications
```typescript
this.wifiWizard2.getConnectedSSID()

  • Returns connected network SSID (only if connected) in success callback, otherwise fail callback will be called (if not connected or unable to retrieve)

  • This does NOT return the BSSID if unable to obtain SSID (like original WifiWizard did)

    this.wifiWizard2.getConnectedBSSID()

  • Same as above, except BSSID (mac) is returned

    this.wifiWizard2.timeout(delay)

  • delay should be time in milliseconds to delay

  • Helper async timeout delay, delay is optional, default is 2000ms = 2 seconds

  • This method always returns a resolved promise after the delay, it will never reject or throw an error

    Example inside async function

    async function example(){
    await this.wifiWizard2.timeout(4000);
    // do something after 4 seconds
    }

    Example inside standard non-async function

    function example(){
    this.wifiWizard2.timeout(4000).then( function(){
    // do something after waiting 4 seconds
    }):
    }

    Thrown Errors

  • TIMEOUT_WAITING_FOR_SCAN on timeout waiting for scan 10 seconds +

  • SCAN_FAILED if unable to start scan

    iOS Functions#

    For functionality, you need to note the following:

  • Connect/Disconnect only works for iOS11+

  • Can't run in the simulator so you need to attach an actual device when building with xCode

  • Will ensure 'HotspotConfiguration' and 'NetworkExtensions' capabilities are added to your xCode project

  • To connect to open network omit ssidPassword or call with false

    this.wifiWizard2.iOSConnectNetwork(ssid, ssidPassword)
    this.wifiWizard2.iOSDisconnectNetwork(ssid)

    Android Functions#

  • WifiWizard2 will automagically try to enable WiFi if it's disabled when calling any android related methods that require WiFi to be enabled

    Connect vs Enable#

    When writing Android Java code, there is no connect methods, you basically either enable or disable a network. In the original versions of WifiWizard the connect method would basically just call enable in Android. I have changed the way this works in WifiWizard2 version 3.0.0+, converting it to a helper method to eliminate having to call formatWifiConfig then add and then enable ... the connect method will now automatically call formatWifiConfig, then call add to either add or update the network configuration, and then call enable. If the connect method is unable to update existing network configuration (added by user or other apps), but there is a valid network ID, it will still attempt to enable that network ID.

    this.wifiWizard2.connect(ssid, bindAll, password, algorithm, isHiddenSSID)

  • ssid should be the SSID to connect to required

  • bindAll should be set to true to tell Android to route all connections from your Android app, through the wifi connection (default is false) optional

  • See WifiWizard2.enable for more details regarding bindAll feature

  • algorithm and password is not required if connecting to an open network

  • Currently WPA and WEP are only supported algorithms

  • For WPA2 just pass WPA as the algorithm

  • Set isHiddenSSID to true if the network you're connecting to is hidden

  • These arguments are the same as for formatWifiConfig

  • This method essentially calls formatWifiConfig then add then enable

  • If unable to update network configuration (was added by user or other app), but a valid network ID exists, this method will still attempt to enable the network

  • Promise will not be returned until method has verified that connection to WiFi was in completed state (waits up to 60 seconds)

    Thrown Errors

  • CONNECT_FAILED_TIMEOUT unable to verify connection, timed out after 60 seconds
  • INVALID_NETWORK_ID_TO_CONNECT Unable to connect based on generated wifi config
  • INTERPUT_EXCEPT_WHILE_CONNECTING Interupt exception while waiting for connection

Disconnect vs Disable#

Same as above for Connect vs Enable, except in this situation, disconnect will first disable the network, and then attempt to remove it (if SSID is passed)

this.wifiWizard2.disconnect(ssid)

  • ssid can either be an SSID (string) or a network ID (integer)

  • ssid is OPTIONAL .. if not passed, will disconnect current WiFi (almost all Android versions now will just automatically reconnect to last wifi after disconnecting)

  • If ssid is provided, this method will first attempt to disable and then remove the network

  • If you do not want to remove network configuration, use disable instead

    Thrown Errors

  • DISCONNECT_NET_REMOVE_ERROR Android returned error when removing wifi configuration

  • DISCONNECT_NET_DISABLE_ERROR Unable to connect based on generated wifi config

  • DISCONNECT_NET_ID_NOT_FOUND Unable to determine network ID to disconnect/remove (from passed SSID)

  • ERROR_DISCONNECT - Android error disconnecting wifi (only when SSID is not passed)

    this.wifiWizard2.formatWifiConfig(ssid, password, algorithm, isHiddenSSID)

  • algorithm and password is not required if connecting to an open network

  • Currently WPA and WEP are only supported algorithms

  • For WPA2 just pass WPA as the algorithm

  • Set isHiddenSSID to true if the network you're connecting to is hidden

    this.wifiWizard2.formatWPAConfig(ssid, password, isHiddenSSID)

  • This is just a helper method that calls WifiWizard2.formatWifiConfig( ssid, password, 'WPA', isHiddenSSID );

    this.wifiWizard2.add(wifi)

  • wifi must be an object formatted by formatWifiConfig, this must be done before calling enable

    Thrown Errors

  • AUTH_TYPE_NOT_SUPPORTED - Invalid auth type specified

  • ERROR_ADDING_NETWORK - Android returned -1 specifying error adding network

  • ERROR_UPDATING_NETWORK - Same as above, except an existing network ID was found, and unable to update it

    this.wifiWizard2.remove(ssid)

  • ssid can either be an SSID (string) or a network ID (integer)

  • Please note, most newer versions of Android will only allow wifi to be removed if created by your application

    Thrown Errors

  • UNABLE_TO_REMOVE Android returned failure in removing network

  • REMOVE_NETWORK_NOT_FOUND Unable to determine network ID from passed SSID

this.wifiWizard2.listNetworks()
this.wifiWizard2.scan([options])

  • Same as calling startScan and then getScanResults, except this method will only resolve the promise after the scan completes and returns the results.

    this.wifiWizard2.startScan()

  • It is recommended to just use the scan method instead of startScan

    Thrown Errors

  • STARTSCAN_FAILED Android returned failure in starting scan

this.wifiWizard2.getScanResults([options])

  • getScanResults should only be called after calling startScan (it is recommended to use scan instead as this starts the scan, then returns the results)

  • [options] is optional, if you do not want to specify, just pass success callback as first parameter, and fail callback as second parameter

  • Retrieves a list of the available networks as an array of objects and passes them to the function listHandler. The format of the array is:

    networks = [
    { "level": signal_level, // raw RSSI value
    "SSID": ssid, // SSID as string, with escaped double quotes: "\"ssid name\""
    "BSSID": bssid // MAC address of WiFi router as string
    "frequency": frequency of the access point channel in MHz
    "capabilities": capabilities // Describes the authentication, key management, and encryption schemes supported by the access point.
    "timestamp": timestamp // timestamp of when the scan was completed
    "channelWidth":
    "centerFreq0":
    "centerFreq1":
    }
    ]

  • channelWidth centerFreq0 and centerFreq1 are only supported on API > 23 (Marshmallow), any older API will return null for these values

    An options object may be passed. Currently, the only supported option is numLevels, and it has the following behavior:

  • if (n == true || n < 2), *.getScanResults({numLevels: n}) will return data as before, split in 5 levels;

  • if (n > 1), *.getScanResults({numLevels: n}) will calculate the signal level, split in n levels;

  • if (n == false), *.getScanResults({numLevels: n}) will use the raw signal level;

    this.wifiWizard2.isWifiEnabled()

  • Returns boolean value of whether Wifi is enabled or not

    this.wifiWizard2.setWifiEnabled(enabled)

  • Pass true for enabled parameter to set Wifi enabled

  • You do not need to call this function to set WiFi enabled to call other methods that require wifi enabled. This plugin will automagically enable WiFi if a method is called that requires WiFi to be enabled.

    Thrown Errors

  • ERROR_SETWIFIENABLED wifi state does not match call (enable or disable)

    this.wifiWizard2.getConnectedNetworkID()

  • Returns currently connected network ID in success callback (only if connected), otherwise fail callback will be called

    Thrown Errors

  • GET_CONNECTED_NET_ID_ERROR Unable to determine currently connected network ID (may not be connected)

    New to 3.1.1+#

    this.wifiWizard2.resetBindAll()

  • Disable bindAll to WiFi network without disconnecting from WiFi

    this.wifiWizard2.setBindAll()

  • Enable bindAll to WiFi network without disconnecting from WiFi

    this.wifiWizard2.canConnectToInternet()

  • Returns boolean, true or false, if device is able to connect to https://www.google.com via HTTP connection (since ping is unreliable)

  • Unknown errors will still be thrown like all other async functions

  • If you called connect or enable and passed true for bindAll, your application will force the ping through wifi connection.

  • If you did not pass true (or passed false) for bindAll, and the wifi does not have internet connection, Android Lollipop+ (API 21+) will use cell connection to ping (due to Android using cell connection when wifi does not have internet) More Details

this.wifiWizard2.canConnectToRouter()

  • As canPingWifiRouter is notoriously unreliable, this method uses HTTP connection to test if able to connect to router (as most routers should have web server running on port 80)

  • Unknown errors will still be thrown like all other async functions

  • This is useful for testing to make sure that your Android app is able to connect to the private network after connecting to WiFi

  • This was added for testing the bindAll feature to support issues with Android Lollipop+ (API 21+) not routing calls through WiFi if WiFi does not have internet connection See Android Blog

  • Attempts to connect router IP HTTP server on port 80 (example: http://192.168.0.1/ where 192.168.0.1 is the automatically detected IP address)

    New to 3.0.0+#

    this.wifiWizard2.isConnectedToInternet()

  • Returns boolean, true or false, if device is able to ping 8.8.8.8

  • Unknown errors will still be thrown like all other async functions

  • If you called connect or enable and passed true for bindAll, your application will force the ping through wifi connection.

  • If you did not pass true (or passed false) for bindAll, and the wifi does not have internet connection, Android Lollipop+ (API 21+) will use cell connection to ping (due to Android using cell connection when wifi does not have internet) More Details

    this.wifiWizard2.canPingWifiRouter()

  • Returns boolean, true or false, if device is able to ping the connected WiFi router IP (obtained from DHCP info)

  • Version 3.1.1+ uses HTTP connection to test if able to connect to router (as ping previous did not work)

  • Unknown errors will still be thrown like all other async functions

  • This is useful for testing to make sure that your Android app is able to connect to the private network after connecting to WiFi

  • This was added for testing the bindAll feature to support issues with Android Lollipop+ (API 21+) not routing calls through WiFi if WiFi does not have internet connection See Android Blog

    this.wifiWizard2.enableWifi()
    this.wifiWizard2.disableWifi()
    this.wifiWizard2.getWifiIP()

  • Returns IPv4 address of currently connected WiFi, or rejects promise if IP not found or wifi not connected

    this.wifiWizard2.getWifiRouterIP()

  • Returns IPv4 WiFi router IP from currently connected WiFi, or rejects promise if unable to determine, or wifi not connected

    Thrown Errors

  • NO_VALID_IP_IDENTIFIED if unable to determine a valid IP (ip returned from device is 0.0.0.0)

    this.wifiWizard2.getWifiIPInfo()

  • Returns a JSON object with IPv4 address and subnet {"ip": "192.168.1.2", "subnet": "255.255.255.0" } or rejected promise if not found or not connected Thrown Errors

  • NO_VALID_IP_IDENTIFIED if unable to determine a valid IP (ip returned from device is 0.0.0.0)

    this.wifiWizard2.reconnect()

  • Reconnect to the currently active access point, if we are currently disconnected.

    Thrown Errors

  • ERROR_RECONNECT Android returned error when reconnecting

    this.wifiWizard2.reassociate()

  • Reconnect to the currently active access point, even if we are already connected.

    Thrown Errors

  • ERROR_REASSOCIATE Android returned error when reassociating

this.wifiWizard2.getSSIDNetworkID(ssid)

  • Get Android Network ID from passed SSID

    this.wifiWizard2.disable(ssid)

  • ssid can either be an SSID (string) or a network ID (integer)

  • Disable the passed SSID network

  • Please note that most newer versions of Android will only allow you to disable networks created by your application

    Thrown Errors

  • UNABLE_TO_DISABLE Android returned failure in disabling network

  • DISABLE_NETWORK_NOT_FOUND Unable to determine network ID from passed SSID to disable

this.wifiWizard2.requestPermission()

  • Request ACCESS_FINE_LOCATION permssion

  • This Android permission is required to run scan, startStart and getScanResults

  • You can request permission by running this function manually, or WifiWizard2 will automagically request permission when one of the functions above is called

    Thrown Errors

  • PERMISSION_DENIED user denied permission on device

this.wifiWizard2.enable(ssid, bindAll, waitForConnection)

  • ssid can either be an SSID (string) or a network ID (integer)

  • bindAll should be set to true to tell Android to route all connections from your Android app, through the wifi connection

  • Android Lollipop+ (API 21+) will not route connections to the WiFi device if it does not have internet connection. Passing true to bindAll will force Android to route connections from your Android app through Wifi, regardless of internet connection.

  • If you are having problems connecting to a local IP through WiFi because it does not have internet, try enabling bindAll and this should fix the problem.

  • During my testing, some versions of Android (5.0 - 7.1.2) would still route connections through WiFi without internet, but it was random that some versions would and would not work.

  • Testing Android Oreo+ (8.0.0+) if wifi does not have internet, 100% of the time it would NOT route connections through WiFi, so you must enable this for Oreo or newer to route connections from your application through wifi without internet.

  • When bindAll is enabled, ALL connections from your app will be routed through WiFi, until you call disconnect or disable

  • See the Google Android Blog for More Details

  • This feature ONLY works for Android Lollipop+ (API 21+), if device is running API older than 21, bindall will be ignored (as API older than 21 does this by default)

  • Enable the passed SSID network

  • You MUST call WifiWizard2.add(wifi) before calling enable as the wifi configuration must exist before you can enable it (or previously used connect without calling disconnect)

  • This method does NOT wait or verify connection to wifi network, pass true to waitForConnection to only return promise once connection is verified in COMPLETED state to specific ssid

    Thrown Errors

    UNABLE_TO_ENABLE - Android returned -1 signifying failure enabling
