B4A Library Simple WIFI library Updated V. 3.07 09-05-2018

This library is based on the library Jem:https://www.b4x.com/android/forum/threads/simple-wifi-library.38601/

Which Jem can no longer maintain.

I needed some methods that the library did not have, for an application I'm doing, and instead of creating a library from scratch, I preferred to take advantage of Jem's library and create those methods that I needed.

I've modified the source code, I have corrected some errors and added new methods that I needed.

I’ve tested on Android 4x, 5x and 6x on different devices and it gives me no error.

V-3.02 by bgsoft

Constants:

WIFI_2_4GHZ_BAND As Int = 1

2.4GHz WIFI Band

WIFI_5GHZ_BAND As Int = 2

5GHz WIFI Band

WIFI_MODE_FULL As Int = 1

In this WIFI lock mode, WIFI will be kept active, and will behave normally. It will attempt to automatically establish a connection to a remembered access point that is within range, and will do periodic scans if there are remembered access points but none are in range.

WIFI_MODE_SCAN_ONLY As Int = 2

In this WIFI lock mode, WIFI will be kept active, but the only operation that will be supported is initiation of scans, and the subsequent reporting of scan results. No attempts will be made to automatically connect to remembered access points, nor will periodic scans be automatically performed looking for remembered access points.
Scans must be explicitly requested by an application in this mode.

WIFI_MODE_FULL_HIGH_PERF As Int = 3

In this WIFI lock mode, WIFI will be kept active as in mode WIFI_MODE_FULL but it operates at high performance with minimum packet loss and low packet latency even when the device screen is off.
This mode will consume more power and hence should be used only when there is a need for such an active connection.

V-3.01 by bgsoft

I have added the "stopScan" method to stop "_ScanDone" events from scans made automatically by the system, in the background.

I have also modified the "startScan" method, adding the parameter "NoEventOnSystemScan" that allows to disable the events coming from Scans made automatically by the system, in the background.

Two new isOnlinePing3 and isOnlinePing4 methods, equivalent to isOnlinePing and isOnlinePing2 but adding a timeout parameter, in milliseconds.

NEW

Call "updateWifiList" to re-activate this events.

UPDATED
startScan(EventName As String, NoEventOnSystemScan As Boolean)

Initializes all objects and scans for WIFI networks. Builds a string array of results (wifis) that can be accessed directly or with a call to updateWifiList.
EventName: Name of the Event to launch when Scan finish (EventName_ScanDone)

Well done, @bgsoft .

This one connects to 2 of the 3 networks here while the 2.07 didn't connect to any at all.

Hello @bgsoft

Would it be possible to add a method to MLScan to stop the scan. I have a service for handling wifi related stuff and after the service is run once I see 'Ignoring event as service was destroyed: scan_scandone' in the log. It would be more efficient to stop the scan and the events being raised when the service is no long active.

Thanks in advance

John.

Hi

I am using this excellent library to write my first (simple) app. Everything works, except I just added a call to WifiChannel and it causes a run-time error thus:

I am using original WifiLibrary from a lot of time and it worked perfectly. Now i am looking my app more closely and i fired a "startScan" with wifi powered off.
In this case the library Powers on the wifi adapter automatically, and in my case it is not a good behaviour.

Is it possible to add isScanAlwaysAvailable() option and perform a wifi scanning with the adapter powered off?
Info: https://developer.android.com/reference/android/net/wifi/WifiManager.html#isScanAlwaysAvailable()

Thanks in advance

I've been looking at the library but don't see a way to create or activate a VPN network (personal hotspot) on a device with this library? Before I assume that isn't possible, I thought I would ask. I'm not the brightest bulb in the socket, ha ha.

Tryed this lib.

Version 3.01 has a stopScan method, however that method aparentetly is not present in 3.02.

In 3.02 the scandone method is keeps being fired (android 6 here), although scan has been requested only once.

Also in 3.01 (the one I'm using, since 3.02 does not include the StopScan) the W1Scan.saveWifiAP, always returns false, even if the connection is achieved.

I noticed that the ScanDone is being fired multiple times because the library registers a broadcast receiver and so every time the OS performs a scan the ScanDone sub get fired.
For avoiding to execute the code in the sub Scandone when not needed you can use for example a boolean variable like this example

B4X:
Sub FireIt
ScanStarted=True
wifi.startscan("wifi")
End sub

Sub wifi_ScanDone
 If ScanStarted==True then
    Scanstarted=False

    '......<Your remaining code here>.....

 End if
End sub

Hi, thanks for saying it, I deleted it by mistake :D.

the W1Scan.saveWifiAP, always returns false, even if the connection is achieved.
I've tried it on several devices and it works fine


In the next version is already corrected the StopScan
