Configuration over power distribution lines
First Claim
1. A circuit-based apparatus comprising:
- a transceiver circuit configured and arranged to communicate over power distribution lines that carry power using alternating current (AC);
a processing circuit configured and arranged tooperate according to configuration data stored in a first memory buffer;
store data from a configuration request received by the transceiver in a second memory buffer;
maintain operation according to the configuration data stored in the first memory buffer until occurrence of a timer event; and
in response to the timer event, operate according to the data from the configuration request.

Abstract
Aspects of the present disclosure are directed toward the use of broadcast transmissions to multiple endpoint devices. These broadcast transmissions can be particularly useful for reducing the communication bandwidth used during transmission of configuration data to the endpoint devices. In order to implement the broadcast communications, the present disclosure describes a mechanism for configuring targeted endpoint devices to be responsive to the broadcast communications. For instance, a configuration command can be sent to each of the targeted endpoint devices. The configuration command can include a virtual ID. The targeted endpoint devices can configure themselves to listen for subsequent broadcast messages addressed to the virtual ID. Configuration data can then be sent using the virtual ID and associated broadcast messages.

16. A method comprising:
-
receiving, using a transceiver circuit, an analog data communication over power distribution lines that carry power using alternating current (AC); and using a processing circuit to operate according to configuration data stored in a memory; in response to receiving a first configuration request, indicating a virtual identifier, storing the virtual identifier in the memory; and in response to receiving a broadcast message specifying a second virtual identifier matching the virtual identifier stored in the memory, operate according to the data in the broadcast message. - View Dependent Claims (17, 18)
