Run the log on this line and see if You get anything from the reader

Intent_StrBuff_Veh = StartingIntent.GetExtra("barcodeStringData")
Log(Intent_StrBuff_Veh)

I'm getting nothing on the B4A log and nothing on the device. I have set the app to "Scan Vehicle Data"

Is Your scanner setup for "intent mode"
Go to the scanner settings and check for that..
If there is nothing in the log then the configuration is wrong..
I know the code works..

Hi Werner
Thank you for your continued support.
Herewith are screenshots of my scanner setting from the Sunmi Partner Portal:

I've tried different settings but nothing:

werner_Fourie · Nov 16, 2022

make sure this is in the manifest..

AddReceiverText(Service1,
<intent-filter >
<action android:name="com.scanner.broadcast" />
</intent-filter>
)

change everything back to where my code was..

.......change on the scanner......
change the broadcast name to com.scanner.broadcast
change raw byte value to dataBytes
don't alter the key value

Scan and check the logs for something.. It will look like garbage..
Send me the logs

Hi Werner

I did exactly as you suggested and I'm still not getting anything. I compiled your code as is and made the changes on the device and on the manifest as well. I did not change a single thing in your code. I have attached some screenshots...

Here are the logs after successfully compiling:

Hi

If B4XPages.MainPage.Barcode_Scann_Mode.Text = "Scan Driver Data" Then
Intent_StrBuff_LIC = StartingIntent.GetExtra("dataBytes")
Log(Intent_StrBuff_LIC) *******Put Log() here...*******

This happens when You Scan a License..
From what country is the licence You are scanning...?

----------------------------------------------
** Receiver (service1) OnReceive ********* This needs to trigger
** Service (service1) Start **

if not Your scanner is not setup correctly

This is the result from the scan after going through the decoder..
result.length = 128
result[0] = 1

Hi Werner. Nothing is happening, nothing in the log. Like you said, it looks like my scanner is not setup correctly. I think it has do to with the AIDL thingy. I have an AIDL file that I have downloaded with the code from the scanner manufacturer. I'm still trying to figure it out.

Johan Schoeman · Nov 20, 2022

There is a field in your setup that says "Fill EditText directly". Try and set it, add just one EditText to your activity and see if the EditText is filled with the scan result when you do a scan.

Setlodi · Nov 20, 2022

Hi Johan
Thank you for your input. I have added a text box to Werner's Scanner application. As you can see in the screenshot, it does scan and input the unencrypted scan result in the EditText box. This is from my drivers license. But as you might be aware, this is only on the "surface".

Johan Schoeman · Nov 21, 2022

Have you tried in the service code to do this in place of what you have

B4X:

Dim content() As Byte = StartingIntent.GetExtra("dataBytes")
strBuff = con.StringFromBytes(content,"ISO8859_1")
Log(strBuff)

Dim content() As Byte = StartingIntent.GetExtra("dataBytes")

Setlodi · Nov 22, 2022

Hi Johan and Werner

I think the Service1 module does not start at all. I've tried everything you suggested but I'm still not getting anything. Now I also added a Log in B4XMainPage to see if something will show and, alas! I could see the logs. Below are the logs that I added:

Testing the Log:

Private Sub CheckBox_Select_Scan_Mode_ValueChanged (Value As Boolean)
    If CheckBox_Select_Scan_Mode.Value = True Then
        service1.Barcode_Mode_Seletion = "Vehicle"
        Barcode_Scann_Mode.Text = "Scan Vehicle Data"
      
        'Test log
        Log("XXXXXXXXXXXX Vehicle " & Barcode_Scann_Mode.Text)
      
    Else 
        service1.Barcode_Mode_Seletion = "Driver"
        Barcode_Scann_Mode.Text = "Scan Driver Data"
      
        'Test log
        Log("XXXXXXXXXXXX Driver " & Barcode_Scann_Mode.Text )
      
    End If
  
End Sub

From this I was able to see the following in the log, as I toggle between Driver and Vehicle selection on my hand held device:

running waiting messages (1)
** Activity (main) Resume **
*** mainpage: B4XPage_Appear [mainpage]
Activity_Resume
----------------------------------------------
PROXIMITY_SensorChanged 1
XXXXXXXXXXXX Vehicle Scan Vehicle Data
XXXXXXXXXXXX Driver Scan Driver Data
XXXXXXXXXXXX Vehicle Scan Vehicle Data
XXXXXXXXXXXX Driver Scan Driver Data
XXXXXXXXXXXX Vehicle Scan Vehicle Data
XXXXXXXXXXXX Driver Scan Driver Data
XXXXXXXXXXXX Vehicle Scan Vehicle Data
XXXXXXXXXXXX Driver Scan Driver Data
XXXXXXXXXXXX Vehicle Scan Vehicle Data
XXXXXXXXXXXX Driver Scan Driver Data

Somehow, the scanner can communicate with the app because I'm using it to toggle between "Scan Vehicle Data" and "Scan Driver Data".

What triggers the Service1 module to start?

Region Service Attribute of Service1:

#StartAtBoot: True

Johan Schoeman · Nov 23, 2022

I understood from post #29 above that you do get a scan result ( string) when you do a scan. Is that correct?

Hi..

Look at the video that i emailed You ..It is working..It is not seeing Your scanner or the scanner is configured wrong..
This part should trigger

This is for when Your scanner is in intent mode..

** Receiver (service1) OnReceive ********* This needs to trigger
** Service (service1) Start **
Service_Start
[B@4f79e86 ************ You need to get some information like this line....

Ok, this is what I've done to check if my scanner works. I went into the DESIGNER and created a EDITTEXT box in Form_1Panel_3. I enlarged the box to fit the screen. After compiling the app, I clicked on the text box on the screen and scanned the driver's license. The unencrypted scan results are displayed in the text box. This is how I was able to get the scan result.

Johan Schoeman · Nov 23, 2022

Is the format of the scanned string correct?

Setlodi · Nov 23, 2022

I didn't do anything to the code. Werner confirmed through a video he shared in his previous post that the system works. This is the original source code from him. All I did was add the text box in design and the logs.

If Your scanner sends a string to a text box then it is not in "intent" mode as my app requires..

Your scan result was where the scanner is in text mode..The scrambled text You see is normal..It needs to be decoded.

That only proves that the scanner itself is working.. It now needs to be decoded from that text box as it is decoded from the intent part..

When You put Your scanner in intent mode, if that is the way You want it to work You must make sure that the scanner is setup correctly for the intent to be received in the app..

My app works with intents..

If You want to use it as a text scanner to text box in my app You are going to have to do much more figuring out what to do..

Hope that helps..

If You live in Gauteng I could assist You over the weekend if You bring all your gear to my place..

Thanks, this helps a lot Werner. I have been going through the settings in the actual scanning device and there's nothing about setting up the Intents. I have sent a message to the manufacturer and they should get back to me in a day or so. I do not want it as a text scanner as this will just confuse things. I will find a way of setting up the intents mode in the scanner and work with your app as it was intended. I will keep you guys informed of my progress. Much appreciation for your continued support.

Hi Werner. Yes, I live in Gauteng. We are available on Saturday 14h00 - 18h00 and on Sunday 09h00 - 12h00. If this doesn't suit you, please suggest an alternative time and we will work around it.

Thanks

Keep POPI act in mind. You cannot collect personal info without concent. Wherever I go and at entry they want to scan my car license and/or driver licence I throw POPI at them and have never been refused entry without scanning as they are all very aware of POPI act.
