Method of establishing communication with wireless control devices
First Claim
1. A method for configuring a radio frequency (RF) control device capable of receiving radio frequency messages on a plurality of radio frequency channels from a first device so as to receive messages transmitted by the first device on a designated one of the radio frequency channels, the method comprising the steps of:
- repeatedly transmitting a beacon message on one of the channels from a beacon message transmitting device;
removing and subsequently restoring power to the control device;
initiating a beacon monitoring mode at the control device;
listening by the control device for the beacon message by scanning each of the plurality of radio frequency channels for a first predetermined period of time;
receiving the beacon message by the control device on one of the channels;
locking on by the control device to the channel on which the beacon message is received;
halting further scanning by the control device in response to the steps of receiving and locking on;
transmitting by the first device a query message to the control device; and
transmitting by the control device a query message response if the control device receives the query message within a second predetermined period of time from when power was restored to the control device.

Abstract
The method of the present invention allows a first wireless control device that is operable to communicate on a predetermined one of a plurality of channels to establish communication with a second wireless control device that may be communicating on any of the plurality of channels. A beacon message is first transmitted repeatedly by the wireless control device on the predetermined channel. The second wireless control device listens for the beacon message for a predetermined amount of time on each of the plurality of channels. When the second control device receives the beacon message on the predetermined channel, the second control device begins communicating on the predetermined channel. The second wireless device may begin listening for the beacon message in response to powering up.
