Soft Keyboard for Input field

Hi All,

i have an input field . when it displays in tablet and set focused ,the Soft keyboard appears automatically.

but we don't want to display that soft Keyboard automatically, as we enter input value by scanner.

please let me know how to restrict the soft keyboard display automatically.

i have used SAP.M.INPUT for input field.

<Input id="matnrId" change="onChangeMatnr" />

Regards,

Vamsi
