I want to generate a Bluetooth initator command barcode in the following format (#FNIaabbccddeeff#) on screen in Android, to automate the paring process.
I'm using zxing library to generate this in Code128 format. The scanner refuses to understand the barcode. But any softscan application on android easily understand the barcode. If I generate a code with barcode.tec-it.com on the PC screen the scanner detect immediately.
In the Socketscan application on google play the same barcode is displayed and the scanner decodes correctly.
The scanner is a Socket Mobile CHS 7ci scanner.
Any idea?
Edit: Solved, I had managed to get a leading space in before the hash tag when building the barcode.

I am new to biometrics. I bought a new Persona U are U 4500 Device and SDK from a vendor. The SDK has some samples (as expected). All of the samples run smoothly except the WebSample. it do not detects my device in addition it gives an error in the console.
Can anyone please help me how to fix this issue and guide me as why am i facing this problem? is it something related to my wss://localhost?
Update
By further diving into the program i found the specified url https://127.0.0.1:52181/get_connection in websdk.client.bundle.min.js when i opened the link it says
{
"code": -2147024894,
"message": "The system cannot find the file specified."
}
Am i missing some file?
I don't have it in front of me now, because I switched back to the U.are.U 2.2.3 SDK, which does not have this feature.
But it sounds like you possibly have not installed the Digital Persona Lite client component. This runs a separate WebSocket service on port 9001 (IIRC) through which the JavaScript client then communicates.
It is described here: https://hidglobal.github.io/digitalpersona-devices/tutorial.html
After installation, you will need to restart.
The call to https://127.0.0.1:52181/get_connection should then respond with details of the WebSocket service, to which the JavaScript client will connect.
NOTE: The WebSkd library requires DigitalPersona Agent running on a
client machine. This agent provides a secure communication channel
between a browser and a fingerprint or card device driver. The
DigitalPersona Agent is a part of a HID DigitalPersona Workstation. It
can be also installed with a DigitalPersona Lite Client. If you expect
your users do not use HID DigitalPersona Workstation, you may need to
provide your users with a link to the Lite Client download, which you
should show on a reader communication error:
A link is provided there to download the Lite client from here: https://www.crossmatch.com/AltusFiles/AltusLite/digitalPersonaClient.Setup64.exe
you just add a script call of the following code "crossorigin = '' ". "crossorigin=''". It will look like this:
<script src="scripts/websdk.client.bundle.min.js" crossorigin="*"></script>
<script src="scripts/fingerprint.sdk.min.js" crossorigin="*"></script>
Is there any method exposed in MOTOROLA DS9208 scanner dll/api to decode the PDF-417 barcodes.
Device Name:- Motorola Scanner
Device Model Number:- DS9208
By default, Pdf417 is readable on the MOTOROLA(currently Zebra) DS9208.
However, MicroPDF417 is in Disable state by default, so read the setting barcode and enable it if necessary.

Pgae 274 10 - 84 DS9208 Product Reference Guide
SDK (including various documents / drivers) can be downloaded from the following page.
DS9208 HANDS-FREE IMAGER SUPPORT
The standardized API materials / libraries are the same as in the previous article.

I'm trying to programmatically control a twain scanner within my custom application. I don't want to show the scanner's native UI.
I set CAP_INDICATORS capability to FALSE, and set CAP_UICONTROLLABLE capability to TRUE.
Then I start the scan using DG_CONTROL / DAT_USERINTERFACE / MSG_ENABLEDS, while ShowUI in TW_USERINTERFACE structure is set to FALSE.
I tested through different scanners. While my Epson DS-30 scanner is working as expected without ui, my Avision A6 scanner still shows a progress UI during scan:
This UI appears when I call DG_IMAGE / DAT_IMAGEINFO / MSG_GET operation, to get the image details from scanner. With DAT_IMAGEINFO command, this A6 scanner start to scan the paper, and after scanning complete, I could finally recieve the TW_IMAGEINFO structure.
I don't receive any TWRC_CHECKSTATUS while setting the UI mode.
So does this particular scanner actually doesn't support twain without UI?
Or could I have something workaround to disable this UI?
Actually a lot depends on the driver implementation.
So what happens is the options you set from the application configures the driver based on the capabilities it supports. If the driver capability for UI-less scanning is not allowed to be configurable by the driver in that case your application implementation may not work as expected.
Please refer to the TWAIN documentation for complete details.
I'm getting a feel for Android TV live channels sample app and Im trying to figure out how and where to change the video src for the sample channels. Can anyone point me in the right direction. Also if it helpls the sample activity takes me to a webpage for the xmltv feed and it says modify {#link com.example.android.sampletvinput.rich.RichFeedUtil#USE_LOCAL_XML_FEED}. If that helps any.
There are two ways to modify the video source for the channels
- Set USE_LOCAL_XML_FEED to true and update the local xml feed with your video.
- Or, if you can host a xml file on a http server, you can upload a feed and change the path for the xml feed from here.
Is it possible to access phone data like (Contact,Message) in android,Iphone using Flash Builder Mobile Development app .... If It's Possible using Adobe air so tell me ..
thanks
If the underlying operating system exposes that data, you can access it using a Native Extension. You may have to write your own Native Extension to do that, though.
You can call these API's -
Accelerometer
GPS
Camera
Microphone
To store data-
Sql Lite Datebases
OS Interactions-
Text Message
Email
Call
Example-
protected function sendMessage(event:MouseEvent):void {
var message:String = "";
message +="sms:";
message+ = sendTo.text;
navigateToURL ( new URLRequest (message));
}
This should open your messaging app. However the data you to want to read is mostly going to be protected. You can write a Native Extension though and plug Flex into it.
