Oct 21th, 2019: Version 14: LocalIP: returns wifi ip if its enabled else the cellular one
Some useful blocks to use in a wireless lan.
Required permissions: android.permission.ACCESS_WIFI_STATE, android.permission.CHANGE_WIFI_STATE
Returns whether Success Message should be suppressed.
Specifies whether Success Message should be suppressed.
Returns whether Warning Message should be suppressed.
Specifies whether Warning Message should be suppressed.
Return the local IP Address. Returns wifi ip if its enabled else the cellular one.
Sponsor of this block is Marius. Thank you!
Return the MAC Address of the device.
Sponsor of this block is Niko. Thank you!
Get current WiFi state: true or false.
Enable WiFi.
You can hide the success message after setting the suppressSuccessMessage property to false.
Note: to be able to test this block, you have to build the app, because the permission CHANGE_WIFI_STATE is not available in the companion app.
Note: starting from Android 10, this method does not work anymore, see also this stackoverflow answer. For Android 10 you might want to try this Activity Starter solution.
Disable WiFi.
You can hide the success message after setting the suppressSuccessMessage property to false.
Note: to be able to test this block, you have to build the app, because the permission CHANGE_WIFI_STATE is not available in the companion app. Note: starting from Android 10, this method does not work anymore, see also this stackoverflow answer.
Get current WiFi SSID (Service Set Identifier).
Note; Starting with Android 8.1 (API 27), apps must be granted the ACCESS_COARSE_LOCATION (or ACCESS_FINE_LOCATION) permission in order to obtain the SSID or BSSID. Apps that target API 29 or higher (Android 10) must be granted ACCESS_FINE_LOCATION. See also this stackoverflow answer.
Therefore just drag a location sensor component into your project and additionally ask for permission ACCESS_FINE_LOCATION.
Get current WiFi BSSID (the MAC address of the access point).
Thank you burrowmoor for being the sponsor of this method.

Therefore just drag a location sensor component into your project and additionally ask for permission ACCESS_FINE_LOCATION.
Connect to a SSID (Service Set Identifier).
If you provide a non existing SSID or wrong password, this just will be ignored and the device will try to connect to a known SSID instead.
Note: Starting from version 7 it is also possible to connect to an open network, i.e. a SSID, which does not have a password. Thank you Robert for being the sponsor of this enhancement.
Note: to be able to test this block, you have to build the app, because the permission CHANGE_WIFI_STATE is not available in the companion app.
Get a list of configured SSIDs (Service Set Identifiers). WiFi must be enabled for this.
Get a list of available SSIDs (Service Set Identifiers). WiFi must be enabled for this.
Note: to be able to test this block, you have to build the app, because the permission CHANGE_WIFI_STATE is not available in the companion app.
Note: Precondition to use this method is to add a location sensor component into your project. Also GPS must be enabled. See the example project about how to use it..
Get current connection info.
For details, see also WiFiInfo documentation.
Check, if 5 GHz Band is supported. Returns true or false.
Get signal strength (RSSI) in a range between 0 and 100.
This algorithm is used to calculate the signal strength..
Get IP address of the access point.
Thank you Eric for being the sponsor of this method.
Disconnect.
Note: after disconnecting the device might reconnect automatically to the next available known network.
Thank you Wei Zheng for being the sponsor of this method.
Return a list of DNS servers (primary and secondary) of the current network.
Note: The method returns the IP address of the gateway router when DNS is not configured inside the router.
Thank you Gabriel for being the sponsor of this method.
Remove a SSID from the network list. Note: starting from Android M, apps are not allowed to remove networks that they did not create.
Event indicating that Available SSIDs (Service Set Identifiers) have been scanned.
A list of the available SSIDs is provided in parameter availableSSIDs. The SSID having the best signal is provided in parameter bestSSID. A list of the corresponding RSSIs is provided in parameter correspondingRSSI. A list of corresponding BSSIs is provided in parameter correspondingBSSIs.
Thank you Tal for being the sponsor of the correspondingRSSI and correspondingBSSI functionality.
Check if the negotiation with the WifiConfiguration was successful, Returns true or false.
Note: Precondition to use the AvailableSSID method is
Tested successfully on Samsung Galaxy A5 (2017) running Android 8.0.
Q1: Please check TaifunWiFi.SSID in Android 9. When I build it with Android 9 (Samsung S9), the result of TaifunWiFi.SSID is <unknown ssid>. But, if I build it with Android 5, the TaifunWiFi.SSID works well. Thank you.
A: You might want to try the example project 'Get Available SSIDs' downloadable from the download section below, which adds a location sensor into the project to get the permission ACCESS_COARSE_LOCATION. Additionally please enable GPS and try using the method SSID again for Android 9 devices. See also here.
