Starts the BluetoothSocket that allows two-way communication between the plugin and the scanner. Options are currently unused.
scanner.trigger = function (onScan, onError);
Triggers the scanner to perform a scan.
onScan is called with the scan result.
onScan may also called multiple times if the scan is triggered by the hardware
button on the scanner.
scanner.disable = function (onSuccess, onError);
Stops the BluetoothSocket that allows two-way communication between the plugin and the scanner.
For all of the above functions, a simple check is made to see if any Bluetooth devices are paired that have a name starting with 'KDC'.
If none are found,
onError is called with a message that prompts the user to pair a KoamTac scanner.
If bluetooth is not switched on, the plugin will:
onErrorwith a message stating that the function could not occur because bluetooth was not switched on
If the user switched bluetooth on through the dialog then the plugin, knowing the users intent to perform a scan,
will try to enable the scanner and subsequent calls to trigger or manual scans from the scanner button should succeed.
If the user elects to not switch bluetooth on through the dialog then a message will be sent to
If bluetooth is switched on, and the KoamTac scanner is paired, but the scanner has not been enabled then
a call to
enable will attempt to enable to scanner and open a
If this attempt succeeds, then all subsequent scans will result in a call to
onScan with the value from the scanner
regardless of whether the scan was triggered by the app or by the scan button on the KoamTac scanner.
If this attempt fails then a failure message will be passed to
onError prompting the user to enable the scanner.
