Abstract

Bluetooth Serial Port and HID profiles are popular with wireless scanner users. However the drawback of these profiles is that no feedback is provided as to weather the data was transmitted successfully or in case of HID that the entire string was transmitted. In order to solve this problem we propose a wrapper application on the PC that would receive data from the scanner over wireless SSI (already established Motorola proprietary protocol), transmit it to the user application as serial data or as key strokes and provide feedback to the scanner over SSI.

and HID profiles are popular with wireless scanner users. However the drawback of these profiles is that no feedback is provided as to weather the data was transmitted successfully or in case of HID that the entire string was transmitted. In order to solve this problem we propose a wrapper application on the PC that would receive data from the scanner over wireless SSI (already established Motorola proprietary protocol), transmit it to the user application as serial data or as key strokes and provide feedback to the scanner over SSI.

PROBLEM

Bluetooth profiles such as HID and SPP are popular with wireless scanner users since they allow for data transmission with no application development on the receiver’s side. However the problem is that there is no feedback or acknowledgement as to whether the entire message made it to the receiver’s application without any errors.

Currently users who desire feedback and knowledge that the data was transmitted have to create their own protocols or buy third party solutions.

SOLUTION

            Create an service on the PC that listens on a desired Bluetooth virtual COM port for transmissions from the scanner, transmits the data portion of the scanner’s communication as key strokes or as serial data and provides feedback to the scanner.

OPERATION
