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

bgsoft · Feb 15, 2017

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.

Events:

isOnline_PingDone(isOnline As Boolean)
Launches when "isOnlinePing5" finishes or when "isOnlinePing6" finishes or timeout
isOnline: Returns True if Internet is available

Methods:

Returns the Link Band of the connected WIFI Access Point
WIFI_2_4GHZ_BAND: 2.4GHz Band
WIFI_5GHZ_BAND: 5GHz Band
Returns 0 on error.

Launches the event "isOnline_PingDone(isOnline As Boolean)" with the ping result
timeout: Maximum waiting time in milliseconds
This method does not check or care what type of network is used
It can be WIFI, 2G, 3G, 4g, WIMAX, etc. It just tests for Internet connectivity
Returns True if success

isOnlinePing6(IpHost As String, timeout As Long) As Boolean

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

isOnlinePing3(timeout As Long) As Boolean
Checks for Internet connection by sending a Ping to Google DNS server (Ip: 8.8.8.8)
timeout: Maximum waiting time in milliseconds
This method does not check or care what type of network is used
It can be WIFI, 2G, 3G, 4g, WIMAX, etc. It just tests for Internet connectivity
Returns True if Internet is available

isOnlinePing4(IpHost As String, timeout As Long) As Boolean
Checks for Internet connection by sending a Ping to IpHost
IpHost: Ip address or Host name
timeout: Maximum waiting time in milliseconds
This method does not check or care what type of network is used
It can be WIFI, 2G, 3G, 4g, WIMAX, etc. It just tests for Internet connectivity
Returns True if Internet is available

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

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!

Yeah, the permissions thing changed with Android 6 so I cam across this in my apps on account of wanting to write to an SD Card. If you click on the List Permissions button at the bottom of the Logs window in the IDE it lists all permissions that need this treatment with an asterix.

@bgsoft I'm glad to see this library is still alive and kicking. Thanks for all of your hard work.

Good morning

Is the signal strength the real and actual frequency measure the phone is receiving, or is just a info variable sent by the cell tower?

vhd_bgh · May 11, 2020

hi
is it possible to "turn on" or "turn off" wifi in this library ?

vhd_bgh · May 22, 2020

Hi
I used this library on several devices and it works fine.
But on "sumsung galaxy j7" and other samsung device it doesn't work!!! ("updateWifiList" and then "ScanDone" function doesn't return anything)
Have you tested this on samsung devices?

Nishan15 · May 24, 2020

isOnline is returning True but isOnlinePing is returning False.

I have tested with working internet then isOnline is true
tested with not working internet then isOnline is false
again I made the internet to work in the same function call but isOnline still remain in false and not changing back to true

B4X:

    StartServiceAt(Me, DateTime.Now + 2 * DateTime.TicksPerMinute, True)
    internetChk

internetChk:

    Dim phn As MLwifi
    Log(phn.isOnline)
    Log(phn.isOnlinePing)
   
    If phn.isOnlinePing Then
        Log(phn.isOnlinePing)
        is_Online = 1
    Else
        is_Online = 0
    End If

Also created a test project and find the screenshot for logs

Hello, I would like to know if the MLwifi.connectWifiAP method has a priority list? Because I am trying to connect a network (saved) and I am not successful in trying to connect to the new network. Everything else worked perfectly.

I was able to switch well between saved networks perfectly
But my problem is "ScanDone" on "Sumsung" devices , It can't return any things!!! (This occurred only on "Sumsung" devices)

bruno.ionaldo · Aug 28, 2020

Actually, my device is samsung and Android 10. But what didn't work was the network switch.

vhd_bgh · Aug 28, 2020

In general, this library seems to have a problem with Samsung phones. Do friends know the cause?

mohammad javad · Sep 5, 2020

Hi @bruno.ionaldo and @vhd_bgh
I think the problem is explained here.
However it's hard for me to use the instead way. I would appreciate if you explain more or let me know simpler way.

Wifi finder and connector

Hi How can I list wifis around and make it possible for my users to choose among them? Is there any official library or native method? I’m using wifi simple library (by bgsoft based on Jim miller library) but it’s not updated past few years and it’s not working well in some new cellphones.

www.b4x.com

I also ask @HotShoe and @bgsoft sincerely to update the library according to latest changes of Android. The library was perfect and useful.
Many thanks.

Tonight I checked the MLWifi library code and compare deprecated methods by https://developer.android.com/reference/android/net/wifi/WifiManager
following functions won't work properly for mostly API>28

StartScan
UpdateWifiList
EnableWifi
ListSavedNetworks
removeWifiAP
isSavedWifiAP and isSavedWifiAP2
ConnectWifiAP and ConnectWifiAP2
disconnectWifiAP
SaveWifiAP and SaveWifiAP2
WifiStrength

functionally all important functions of MLWifi Library will no longer work properly ( for API>28)

I’m not professional but I think the most important problem is some classes which are used in MLWifi library are deprecated in android 10, no matter which device is used. I tested my project on galaxy s6 ( android 7 I think) and it’s ok

I'm trying to find an example using this library. I liked the functionality of this library, but how to put it into practice? I want to use Wifi to send requests to the head unit (server). I found only this post, but this version does not run on my SDK 21 smartphone. Probably need to make some additions to the manifest?
