Dealing with a Microvision ROV barcode scanner can be quite tricky. Of course, the device is scanning bar-codes immediately. But the data is sent in a special format and requires a confirmation by the receiver. That's the reason for this blog entry. By default the ROV scanner (in our case a MS2200-BT) buffers all scanned bar codes internally. The receiver (e.g. your PC or smartphone) is required to confirm each received bar code to delete it from the ROV's memory. If such a confirmation is missing the ROV scanner sends the same bar code over and over. The ROV scanner appends a 4 digit serialization number to each scanned bar-code. This serialization number is sent (along with the barcode data) to the receiver. The receiving device is required to acknowledge the bar-code by sending back the serialization number along with an appended ACK character (hex 06) to the ROV scanner. Now let's demonstrate how to configure TEC-IT's software wedge TWedge to work with a Mi...
