1. A method for establishing and maintaining a bi-directional wireless communication link between a host device and a barcode reader, the method comprising:
generating a unique identification code (UIC), the UIC excluding a media access control (MAC) address of a host device radio;
encoding the UIC, a communication protocol indicator, and a default-setting trigger in a barcode, wherein the communication protocol indicator is indicative of a communication protocol to be used to establish the bi-directional wireless communication link;
displaying the barcode on at least one of a display of the host device via an application or a print media of the host device via printing the barcode on the print media;
capturing an image including the barcode via the barcode reader;
processing, via the barcode reader, the image to (i) decode the barcode and extract the UIC from the barcode, and (ii) detect a presence of the communication protocol indicator in the barcode;
advertising, via a barcode reader radio, the UIC;
detecting, via the host device, the barcode reader advertising the UIC;
responsive to the host device detecting the barcode reader advertising the UIC, pairing the host device with the barcode reader, based at least in part on the communication protocol indicator, to establish the bi-directional wireless communication link; and
responsive to the processing the image to decode the barcode and detect, by the barcode reader. a presence of the default-setting trigger in the barcode, at least some settings of the barcode reader are set to their default settings.
