Hi @bgsoft,

Regarding the method updateWiFiList,

According to the documentation, "This method returns a string array containing the access points from the most recent scan, including background scans done automatically by the Android WifiManager."

I would like to suggest that you include a (possibly optional) parameter which when true make updateWiFiList force the Android WiFiManager to do a new Wi-Fi AP scan. The reason for this request is that in some situations, the AP list can be eventually outdated as the phone is moved around in an environment with several APs (like my house which has four APs...).

I'm aware that recent Android versions are gradually limiting the number of times an app can force the WiFiManager to do a AP scan. But that's not a problem, for my app would not call repeatedly for a forced scan and that would be done only in foreground.

Regards,

Hi, @bgsoft, any chances?

Best,

Hi Paulo:

Sorry I have not answered you before, but these last months I am very busy.

What you ask is already done. Just make another updateWiFiList call again.

In the initialization already contains that parameter, I put it in version 3.01 :

V-3.01
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)
NoEventOnSystemScan: Launches events only on requested scans (true) or on all scans (false), including system background scans.
THIS METHOD SHOULD ONLY BE CALLED ONCE!

Regarding your question of the difference between WiFiSignalPct and WiFiStrength, it is already in version 3.0, they are the same:

WifiStrength As Int
Returns the WIFI signal strength in percentage as an integer (0 to 100)
Returns 0 on error
This method fails in some devices. Use WifiSignalPct() instead

Hello,
I am using this Library since 1,5 years and it works very well.
Now I have a new Smartphone and if it is connected to wifi, "wifi.WifiSSID" returns <unknown ssid>.
Has anyone else the same problem?

Others may be able to provide a better answer, but I seemed to get this when I wasn't connected to Wifi, but to the cellular network.

Just turn on your device location to reveal ssid

At the risk of being accused of double-posting a question, I'm going to post here because my post in the Bugs & wishlist forum has so far been unanswered. I won't repeat the entire post (Simple Wifi (MLWifi) not working correctly with Android 9) - however the upshot is that on Android 9 devices, the library is reporting isWifiConnected as false, even when an app is connected to an access point.

From another post, it seems that this might only happen if the AP doesn't have internet access - however I haven't looked into this because in my case I'm seeing the issue when a B4A app is trying to connect to a B4R app that's creating an access point that isn't connected to the internet anyway. In my other post (referred to above) there is a B4A app & a B4R app that when run together will reproduce the issue.

Hi, I tested with a samsung galaxy s8 + with android 9 and isWifiConnected works correctly.
Even if the mobile data is stopped or the location.
I already answered in the other post (Bugs & wishlist)

Hi, I have tested your project on a Samsung Galaxy 8+ with Android 9 and is WIFIConnected works correctly.
Even if the mobile data is stopped or the location.

I have placed at the beginning of Public Sub ConnectToAP

B4X:

  LogColor ("testWiFi.isWifiConnected" & testWiFi.isWifiConnected, Colors.Blue)

And it returns TRUE

Per my reply in our PMs, I tested the updates you sent me & they do not work on an Android 9 device if the connected AP is not also connected to the internet.

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.

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

stopScan
Stops events launched on system background scans, if enabled in "startScan".
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)

rosippc64a · Oct 7, 2019

Hi All!
I use the mlwifi 3.07 lib in the demo program. My android version is 7.1.2. The demo use only libs core and mlwifi. the demo works like a charm.

If I use the mlwifi lib in a complex program what use 36 other libs also (only b4a official libs), I think the mlwifi should works the same, isn't it?
I think it should. And the MLwifi works too, but the MLScan doesn't. :-(

B4X:

Dim wifi As MLwifi '<- works good
Dim scan As MLScan '<-works bad

MLWifi doing its job perfectly, but the MLScan reports 0 wifi network on the same device where the demo worked well.
No error, only reports 0. I use the same code, the same activity as in demo.
Can you imagine, that some other library prevents its work?

rosippc64a · Oct 8, 2019

SOLVED!!!!
Though there was no clue in demo program (nor in manifest) about adding any extra permission, but I found in forum that I have to ask permission:

B4X:

        If Not(rp.Check(rp.PERMISSION_ACCESS_FINE_LOCATION)) Then
            rp.CheckAndRequest(rp.PERMISSION_ACCESS_FINE_LOCATION)
            Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
            Log($"${Permission} status: ${rp.Check(rp.PERMISSION_ACCESS_FINE_LOCATION)}"$)
            pDoEvents
        End If

so everithing is working!

RickKik · Feb 28, 2020

Hi. Is there any simple example how to use this lib?
for example, so that my phone could connect to some network

sorex · Feb 28, 2020

you can use it like this

B4X:

If wifi.WifiSSID.Contains(MyLocationWifiSSID)=False Then
LogColor($"Connected to wrong SSID (${wifi.WifiSSID}) > Switching to ${MyLocationWifiSSID}/${MyLocationWifiPassword}"$,Colors.Red)
wifi.disconnectWifiAP
wifi.saveWifiAP(MyLocationWifiSSID,2,MyLocationWifiPassword,True)
End If

which switches to the correct access point if not connected or connected to a wrong one. you can put that in a timer and check every minute or so.
