System and method for mitigating the effects of interferers while performing conditional device scan

摘要

A method, a personal area network device operating as a slave, and a short range communications device operating as a slave are disclosed. A data storage 208 may store at least one protocol-specific channel criterion for a connection with a master short range communication device 104. A short range transceiver 108 may execute a preliminary device scan of a scanning set of communication channels for radio frequency energy. A processor 204 may decide to execute a full device scan based in part on the protocol-specific channel criterion.

主权项

1. A short range communication device configured to operate as a slave communication device, comprising:
a data storage configured to store at least one protocol-specific channel criterion for a connection with a master short range communication device; a short range transceiver configured to execute a preliminary device scan of a scanning set of communication channels to detect radio frequency energy; and a processor configured to execute a full device scan based in part on the protocol-specific channel criterion, wherein the detected radio frequency energy matches an expected condition associated with the protocol specific criterion, and wherein the protocol-specific channel criterion comprises an initial radio frequency energy level of an initial channel of a protocol-specific channel subset corresponding to a prior pairing between the slave communication device and the master short range communication device.
