Datalogic Cordova Plugin

Library that exposes the Datalogic Android (Java) SDK as a Cordova plugin. It lets you receive barcode data from the scanner, as well as configure various scanner and device settings. It is available as a npm package for easy consumption here: @datalogic/cordova-plugin-datalogic.

Installation

You can install the plugin from the npm registry as follows:

npm i @datalogic/cordova-plugin-datalogic

...or use the following Cordova CLI command:

cordova plugin add @datalogic/cordova-plugin-datalogic

or, if you are using ionic, this ionic command:

ionic cordova plugin add @datalogic/cordova-plugin-datalogic

or, if you are using PhoneGap CLI, this phonegap command:

phonegap plugin add @datalogic/cordova-plugin-datalogic

## Publish new version

Install and use the [np tool](https://github.com/sindresorhus/np):

``` bash
npm install --global np
np

Sample apps

Several Ionic sample applications are provided to demonstrate using the plugin. You can find them here.

API Reference

All functions are asynchronous. All functions will, at a minimum, include successCallback and errorCallback parameters, both of which are callback functions.

• successCallback will be called in normal cases, and will return an appropriate JSON object.

• errorCallback will be called when there was an error, and will return a single error string.

Namespaces

| Namespace | Description |-----------|------------ | barcodeManager | receive barcode data | autoScanTrigger | work the the autoscan features | keyboardManager | set usable device triggers | ledManager | control device LEDs | scannerProperties | define availabled symbologies

barcodeManager

| Function | Description |----------|------------ | addReadListener | Register to recieve barcode data on each scan. | pressTrigger | Simulate a trigger button press. | releaseTrigger | Simulate a trigger button release.

.addReadListener(successCallback, errorCallback): Object

Register to recieve barcode data on each scan. successCallback will be called every time a barcode is successfully scanned. Therefore, you will typically only need to call barcodeManager.addReadListener() once in your application.

Response

• barcodeData : string - the barcode data scanned.
• barcodeType : string - will be one of the BarcodeID values defined in the BarcodeID class in the Datalogic Android SDK.

{
   "barcodeData": "EUG2997",
   "barcodeType": "CODE128"
}

Example

declare let barcodeManager : any;
...
barcodeManager.addReadListner(
   (data) => {
     parsedData = JSON.parse(data);
     alert(parsedData.barcodeData + ", " + parsedData.barcodeType);
   },
   (err)=>{ alert(err); }
);

.pressTrigger(successCallback, errorCallback): Object

Call this method to simulate a trigger button press. The method does not always immediately start a capture; instead it behaves like pressing a physical scan button.

Response

string with success message

Example

barcodeManager.pressTrigger(
  (data) => { alert(data); },
  (err) => { alert(err);}
);

.releaseTrigger(successCallback, errorCallback): Object

Call this method to simulate a release of a trigger button. The method does not always immediately stop a capture; instead it behaves like releasing a physical scan button.

Response

string with success message

Example

barcodeManager.releaseTrigger(
  (data) => { alert(data); },
  (err) => { alert(err);}
);

autoScanTrigger

| Function | Description |----------|------------ | isAvailable | Determine if the auto scan feature is available on this device. | getSupportedRanges | Get the supported ranges of the autoscan feature. | getCurrentRange | Get the current range of the autoscan feature. | setCurrentRange | Set the current range of the autoscan feature.

.isAvailable(successCallback, errorCallback): Object

Determine if the auto scan feature is available on this device.

Response

• available : boolean - indicates if autoscan is supported or not on this device.

{ "available": true }

Example

declare let autoScanTrigger : any;
isAvailable : boolean = false;
...
autoScanTrigger.isAvailable(
  (data) => {
    this.isAvailable = JSON.parse(data).available;
    alert(this.isAvailable);
  },
  (err) => { alert(err); }
);

.getSupportedRanges(successCallback, errorCallback): Object

Get the supported ranges of the autoscan feature.

Response

supportedRanges : array - provides array of ranges device supports. The array will be empty if device deos not support autoscan. Each object in the array contains:

• id : integer - unique value for a step in the supported ranges
• name : string - descriptive text related to the id

If AutoScan is not supported by device:

{ "supportedRanges":[] }

If AutoScan is supported:

{
  "supportedRanges":[
  {
    "id":0,
    "name":"Near"
  },
  {
    "id":1,
    "name":"Intermediate"
  },
  {
    "id":2,
    "name":"Far"
  }
  ]
}

Example

declare let autoScanTrigger : any;
autoScanTrigger.getSupportedRanges(
  (data) => {
    alert(JSON.parse(data).supportedRanges);
    if(this.supportedRanges.length == 0)
      alert("Device does not support Auto Scan");
  },
  (err) => { alert(err); }
);

.getCurrentRange(successCallback, errorCallback): Object

Get the current range of the autoscan feature.

Response

currentRange : object - contains 2 fields:

• id : integer
• name : string

If AutoScan is not supported by device:

{ "currentRange":null }

If AutoScan is supported:

{
  "currentRange":
  {
      "id":1,
      "name":"Intermediate"
  }
}

Example

declare let autoScanTrigger : any;
autoScanTrigger.getCurrentRange(
  (data) => {
    alert(JSON.parse(data).currentRange);
  },
  (err) => { alert(err); }
);

.setCurrentRange(id, successCallback, errorCallback): Object

Set the current range of the autoscan feature.

id : integer - should match one of the id values retrevied by the getSupportedRanges function.

Response

string with success message

Example

Set current range to "Intermediate"

autoScanTrigger.setCurrentRange(
  0,
  (data) => { alert(data); },
  (err) => { alert(err); }
);

keyboardManager

| Function | Description |----------|------------ | getAllAvailableTriggers | Get all the available triggers of the device. | setAllAvailableTriggers | Set all the devices triggers on or off. | setTriggers | Set one or more triggers on or off.

.getAllAvailableTriggers (successCallback, errorCallback): Object

Get all the available triggers of the device.

Response

triggers : array - each object in the array contains:

• enabled : boolean
• id : integer
• name : string

Typical resopsnse:

{
    "triggers":[
    {
        "enabled":true,
        "id":3,
        "name":"Front Trigger"
    },
    {
        "enabled":false,
        "id":4,
        "name":"Auto Scan Trigger"
    },
    {
        "enabled":false,
        "id":5,
        "name":"Motion Trigger"
    }
    ]
}

Example

keyboardManager.getAllAvailableTriggers(
  (data) => { alert(JSON.parse(data).triggers); },
  (err) => { alert(err); }
);

.setAllAvailableTriggers(enable, successCallback, errorCallback): Object

Set all the devices triggers on or off.

Response

string with success message

Example

Turn all triggers on.

keyboardManager.setAllAvailableTriggers(
  true,
  (data) => { alert(data); },
  (err) => { alert(err); }
);

.setTriggers(config, successCallback, errorCallback): Object

Set one or more triggers on or off. You will likely call getAllAvailableTriggers, edit the enabled flags of each returned object as desired, and then resubmit by calling setTriggers.

config : array - each ojbect in the array represents an individual trigger. Each object in the array contains:

• id : integer
• enabled : boolean

Response

string with success message

Example

//an array os supported triggers
triggers:{id: number, name: string, enabled: boolean}[]  = [];
