Abstract
Systems are provided for secure actuation of a device such as a moveable barrier operator. In certain embodiments, portions of communications are configured in order to cause information to be added to or deleted from a memory of one of the devices.
Claims15
A method of operating a first device configured to communicate with a second device to cause the second device to reconfigure the first device, the method comprising:
- setting at least a portion of a first changing code of the first device to a set value;
- transmitting from the first device a first message that includes at least a first fixed code and the first changing code having the set value;
- receiving by the first device a second message including a second fixed code and second changing code, wherein a portion of the second message is selected by the second device in response to the set value of the first changing code and includes an instruction specifying one of a single-sided learning protocol and a dual-sided learning protocol;
- and
- reconfiguring a memory of the first device based on the instruction of the portion of the second message selected in response to the set value of the first changing code.
An apparatus configured to communicate with a device to cause the device to reconfigure the apparatus, the apparatus comprising a control circuit and a memory, the control circuit configured to:
- set at least a portion of a first changing code to a set value upon being placed in a specific mode;
- transmit a first message that includes at least a first fixed code and the first changing code having the set value;
- receive a second message including a second fixed code and second changing code, wherein a portion of the second message selected by the device in response to the set value of the first changing code and includes an instruction specifying one of a single-sided learning protocol and a dual-sided learning protocol;
- and
- reconfigure the memory based on the instruction of the portion of the second message selected in response to the set value of the first changing code.
A device configured to reconfigure an apparatus upon receiving instructions from the apparatus, the device configured to:
- receive from the apparatus a first message that includes at least a first fixed code and a first changing code set to a set value;
- select a learning protocol comprising one of single-sided learning protocol or a dual-sided learning protocol based on the first changing code;
- and
- send a second message including a second fixed code and second changing code, a portion of the second message including an instruction based on the selected learning protocol, wherein the instruction of the portion of the second message is configured to cause the apparatus to modify a first memory.
