Assignee: BECTON, DICKINSON AND COMPANY
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A device configured for pairing with a second device for wireless communication therebetween, the device comprising:
a radio frequency (RF) interface for transmitting and receiving RF signals, the received RF signals comprising advertising signals of selected duration transmitted from the second device at selected intervals in a selected RF range; and
a controller configured to
scan for signals in the selected radio frequency range, the controller being provided with signal strength data related to respective signals detected when scanning;
determine whether the signal strength data for at least one of the detected signals satisfies signal strength criteria whereby the signal strength data is greater than a selected minimum signal strength criterion and is less than a selected maximum signal strength criterion;
determine whether the detected signals are from either the second device or another device; and
send the second device a pairing command when the detected signals satisfy the signal strength criteria and the controller determines that the detected signals are only from the second device and not from another device, and prevent pairing with the second device when the detected signals are determined to also be from another device.
