Method and apparatus for binding wireless devices
One embodiment includes a method for designating, at a first device, one of a first plurality of wireless channels as a bind channel, then transmitting a channel change request message using a second plurality of wireless channels, wherein the channel change request includes which one of the plurality of wireless channels is a designated bind channel, transmitting a bind request message using the designated bind channel, and then receiving a bind response message from a second wireless device using the designated bind channel.
1. A method comprising:
at a first wireless device, designating one of a first plurality of wireless channels as a bind channel;
automatically and without human intervention switching from a normal transmission strength of the first wireless device to a reduced transmission strength of the first wireless device;
transmitting by the first wireless device, at the reduced transmission strength, a channel change request message using a second plurality of wireless channels, wherein the channel change request includes which one of the plurality of wireless channels is a designated bind channel;
transmitting by the first wireless device, at the reduced transmission strength, a bind request message using the designated bind channel; and
receiving a bind response message from a second wireless device using the designated bind channel.
2. The method of claim 1 , wherein the reduced transmission strength reduces a range of an RF link between the first and second wireless devices when communicating during a bind operation.
3. The method of claim 1 , further comprising configuring the first wireless device to exchange data with the second wireless device in response to the receiving of the bind response message.
4. The method of claim 2 , wherein the configuring of the first wireless device includes increasing the range of the RF link.
5. The method of claim 3 , wherein the configuring of the first wireless device includes changing to a new channel for normal communication, wherein new channel information is included in the bind response message received from the second wireless device.
6. A method comprising:
responsive to a first wireless device automatically and without human intervention switching from a normal transmission strength of the first wireless device to a reduced transmission strength of the first wireless device,
receiving by a second wireless device a channel change request message transmitted by the first wireless device, at the reduced transmission strength, on one of a plurality of wireless channels, the channel change request including data indicating which one of the plurality of wireless channels is a designated bind channel;
configuring the second wireless device to receive messages on the designated bind channel;
receiving by the second wireless device a bind request message, transmitted by the first wireless device at the reduced transmission strength, on the bind channel; and
transmitting by the second wireless device a bind response message on the bind channel.
7. The method of claim 6 , wherein the reduced transmission strength reduces a range of an RF link between the first and the second wireless devices when communicating using the bind channel.
8. The method of claim 6 , further comprising:
selecting a channel for normal communication to include in the bind response message; and
configuring the second wireless device to communicate messages with the first wireless device on the selected channel for normal communication after the transmission of the bind response message.
9. The method of claim 8 , wherein the configuring of the second wireless device includes increasing a range of an RF link.
10. A method comprising:
at a first wireless device, automatically and without human intervention switching from a normal transmission strength of the first wireless device to a reduced transmission strength of the first wireless device;
designating one of a plurality of wireless communications channels as a bind channel;
transmitting by the first wireless device, at the reduced transmission strength, a channel change request message on each of the plurality of wireless communications channels, wherein the channel change request includes which one of the plurality of wireless channels is a designated bind channel;
receiving by a second wireless device the channel change request message;
configuring the first wireless device to transmit messages on the designated bind channel;
configuring the second wireless device to receive messages on the designated bind channel;
transmitting by the first wireless device a bind request message, at the reduced transmission strength;
receiving by the second wireless device the bind request message;
transmitting by the second wireless device a bind response message; and
receiving by the first wireless device the bind response message.
11. The method of claim 10 , wherein the reduced transmission strength reduces a range of an RF link between the first and the second wireless devices when communicating using the bind channel.
12. The method of claim 10 , further comprising:
selecting at the second wireless device a channel for normal communication to include in the bind response message; and
configuring the second wireless device to communicate messages with the first wireless device on the selected channel for normal communication after the transmission of the bind response message.
