Abstract

A blue-tooth communication system and a broadcasting method therefor are provided. The broadcasting method includes: detecting N blue-tooth receivers in a blue-tooth range of a blue-tooth transmitter; broadcasting a data package during at least one transmitting timing window by the blue-tooth transmitter; and receiving N returned data packages which are respectively returned by the corresponding blue-tooth receivers by the blue-tooth transmitter during N receiving timing windows. At least one of the N returned data packages includes an acknowledge message which is recorded in a header field of the corresponding returned data package.

First claim

What is claimed is:

1. A broadcasting method for a blue-tooth communication system, comprising:
detecting N blue-tooth receivers in a blue-tooth range of a blue-tooth transmitter, wherein N is a positive integer;
broadcasting a data package by the blue-tooth transmitter during at least one transmitting timing window; and
during N receiving timing windows, receiving N returned data packages which are respectively returned by the corresponding blue-tooth receivers by the blue-tooth transmitter during N receiving timing windows, wherein at least one of the N returned data packages includes an acknowledge message which is recorded in a header field of the corresponding returned data package;
wherein one of the received returned data packages is to indicate that the data package was a broadcast data package.

2. The broadcasting method according to claim 1 , wherein the header field comprises an address field, a category or type field, a flow field, a reply field, a sequentially numbering field and a header error control field.

3. The broadcasting method according to claim 2 , wherein the acknowledge message is recorded in the address field, the category or type flow field, the flow field and the reply field.

4. The broadcasting method according to claim 1 , further comprising: performing adjustment on the broadcasting operation of the data package according to the acknowledge message.

5. A blue-tooth communication system, comprising:
a blue-tooth transmitter, having a blue-tooth range; and
N blue-tooth receivers, arranged in the blue-tooth range,
wherein the blue-tooth transmitter broadcasts a data package during a transmitting timing window to transmit the data package to the blue-tooth receivers,
the blue-tooth receivers respectively return N returned data packages to the blue-tooth transmitter, and at least one of the returned data packages includes an acknowledge message which is recorded in a header field of the corresponding returned data package, wherein N is a positive integer,
wherein one of the received returned data packages is to indicate that the data package was a broadcast data package.

6. The blue-tooth communication system according to claim 5 , wherein the header field comprises an address field, a category or type field, a flow field, a reply field, a sequentially numbering field and a header error control field.

7. The blue-tooth communication system according to claim 6 , wherein the acknowledge message is recorded in the address field, the category or type flow field, the flow field and the reply field.

8. The blue-tooth communication system according to claim 5 , the blue-tooth transmitter further performs adjustment on the broadcasting operation of the data package according to the acknowledge message.

9. The method of claim 1 , further comprising receiving a communication from at least one receiver, the communication to indicate a receiving state instead of a returned data package.
