a peripheral device; and
a host device including:
a host receiver configured to receive wireless communications from the peripheral device, and
a proximity sensor activator, the peripheral device including:
a proximity sensor configured to be triggered by a signal from the proximity sensor activator when the proximity sensor detects that the peripheral device is located within a selected proximity to the host device,
a bind logic circuit coupled to the proximity sensor to initiate repeated transmission of a bind mode request from the peripheral device to the host receiver based on the proximity sensor being triggered,
the bind mode request identifying a communication channel to be used by the peripheral device to communicate data to the host device, and
the host receiver further configured to receive data from the peripheral device over the communication channel identified in the bind mode request; and
a transmitter configured to transmit the bind mode request, wherein a transmit power of the transmitter is reduced to transmit the bind request within a reduced communication range.
