Abstract
Techniques for connecting and disconnecting cordless scanners to/from host devices are disclosed herein. A transceiver of an example barcode reader is configured to attempt to establish a wireless connection with a host device (e.g., repeatedly) over a first period of time. Responsive to failing to establish the connection with the host device over the first period of time, the barcode reader enters a power-saving mode. During the power-saving mode at least one of the transceiver, a decode engine, a peripheral sensor, and an imaging engine of the barcode reader are deactivated. The wireless transceiver of the barcode reader is configured to attempt to re-establish the wireless connection with the host device after (i) a passage of a second period of time following the first period of time, wherein the second period of time is greater than the first period of time; or (ii) a receipt of an interrupt signal.
