Abstract

A barcode reader may include barcode reading hardware, which may include an image sensor. The image sensor may capture an image of a barcode within a field of view. The barcode reading hardware may also include a communication interface for output of decoded data to a remote computing system. The barcode reader may also include volatile memory and non-volatile memory. The non-volatile memory may include start-up instructions. The barcode reader may also include a processor. The processor may be configured to, upon power-up of the barcode reader, execute the start-up instructions to obtain firmware for operating the barcode reader from a remote configuration server, load the firmware to the volatile memory, and commence execution of the firmware to commence barcode reading functions of the barcode reader without performing a re-boot operation.

First claim

What is claimed is:

1. A host device coupled to a barcode reader, the barcode reader comprising an image sensor for capturing an image of a barcode within a field of view of the barcode reader, the host device comprising:
a point-to-point communication interface;
a network interface;
a processor;
memory in electronic communication with the processor; and
instructions stored in the memory, the instructions being executable by the processor to:
establish a point-to-point connection with the barcode reader via the point-to-point communication interface;
determine that the barcode reader is in a state wherein executable instructions necessary for providing, to the host device, data decoded from the barcode within the field of view of the barcode reader, are not present within memory of the barcode reader;
use the network interface to connect to a configuration server and to receive, from the configuration server, executable instructions required for the barcode reader to be capable of providing, to the host device, the data decoded from the barcode within the field of view of the barcode reader;
provide the executable instructions to the barcode reader via the point-to-point connection; and
receive from the barcode reader, via the point-to-point communication interface, the data decoded from the barcode within the field of view of the barcode reader only after the executable instructions have been loaded to volatile memory of the barcode reader.
