Updating electrical devices with limited communication capability in integrated networks
A system for providing data to electrical devices in an interconnected network can include a user system disposed in a volume of space, where the user system has a communication range, where the user system broadcasts multiple communication signals into the volume of space. The system can also include an electrical device disposed within the communication range of the user system, where the electrical device includes a controller, where the controller can retrieve first information from a first communication signal, where the information includes a file identification for a file and a number of blocks in the file. The controller can also generate a table for the number of blocks in the file and retrieve second information from a second communication signal, where the second information comprises a first block of the file. The controller can also store the first block of the file in the table.
1. A system for providing data to electrical devices in an interconnected network, the system comprising:
a user system disposed in a volume of space, wherein the user system has a communication range, wherein the user system broadcasts, using a first communication protocol, a plurality of communication signals into the volume of space;
a first electrical device disposed in the volume of space and within the communication range of the user system, wherein the first electrical device comprises a first receiver and a first controller coupled to the first receiver, wherein the first receiver receives the plurality of communication signals broadcast by the user system, wherein the first controller:
retrieves first information from a first communication signal, received by the first receiver, of the plurality of communication signals, wherein the first information comprises a first file identification for a first file and a first number of blocks in the first file;
generates a first table for the first number of blocks in the first file;
retrieves second information from a second communication signal, received by the first receiver, of the plurality of communication signals, wherein the second information comprises a first block of the first file; and
stores the first block of the first file in the first table; and
a second electrical device disposed in the volume of space and within the communication range of the user system, wherein the second electrical device comprises a second receiver and a second controller coupled to the second receiver, wherein the second receiver receives the plurality of communication signals broadcast by the user system, wherein the second controller:
retrieves the first information from the first communication signal, received by the first receiver, of the plurality of communication signals;
determines, based on the first information, that the second electrical device is not an intended recipient of the plurality of communication signals; and
ignores a remainder of the plurality of communication signals.
2. The system of claim 1 , wherein the first controller further:
retrieves the second information from a third communication signal, received by the first receiver, of the plurality of communication signals, wherein the second information comprises the first block of the first file; and
discards the second information from the third communication.
3. The system of claim 1 , wherein the first controller further:
retrieves third information from a third communication signal, received by the first receiver, of the plurality of communication signals, wherein the third information comprises a second block of the first file, wherein the first table is complete after the second block is added to the first table; and
implements the first file.
4. The system of claim 3 , wherein the first controller further:
performs an action to indicate that all blocks of the first file are received.
5. The system of claim 3 , wherein the second block is placed before the first block in first table based on the third information.
6. The system of claim 1 , wherein the first electrical device is unable to transmit under the first communication protocol.
7. The system of claim 1 , wherein the user system receives the first file from a network manager using a second communication protocol.
8. The system of claim 7 , wherein the first communication protocol is Bluetooth Low Energy.
9. The system of claim 1 , wherein the first electrical device comprises a light fixture.
10. The system of claim 1 , wherein the first electrical device comprises an integrated sensor device.
11. The system of claim 1 , wherein the plurality of communication signals are radio frequency signals.
12. The system of claim 1 , wherein the first information of the first communication signal further comprises an identification of the electrical device.
13. The system of claim 1 , wherein the first information of the first communication signal further comprises an identification of the user system.
14. The system of claim 1 , wherein the controller further:
retrieves third information from a third communication signal, received by the first receiver, of the plurality of communication signals, wherein the third information comprises a second file identification for a second file and a second number of blocks in the second file;
generates a second table for the second number of blocks in the second file;
retrieves fourth information from a fourth communication signal, received by the first receiver, of the plurality of communication signals, wherein the fourth information comprises a first block of the second file; and
stores the first block of the second file in the second table.
