1. A polling method compliant to Bluetooth protocol for increasing transfer efficiency, comprising:
- a master determining a first predetermined address as an instruction of a predetermined protocol;
wherein the predetermined protocol enables the master to send one single polling packet for a set of slaves, which support the predetermined protocol, of a plurality of slaves, responding in sequence;
wherein the master and the plurality of slaves belong to a Bluetooth piconet;
the master sending a polling packet having the first predetermined address to the plurality of the slaves; and
the set of the slaves supporting the predetermined protocol responding to the polling packet in sequence.

Abstract
A polling method compliant to Bluetooth protocol is utilized for increasing transfer efficiency. In a Bluetooth piconet, a master queries each slave to determine the slaves supporting a predetermined protocol. The master determines a predetermined address as the instruction of the predetermined protocol. When the master sends a polling packet with the predetermined address to the supporting slaves, the supporting slaves can respond in sequence. In this way, even if the supporting slaves increase, the master only has to send one single polling packet for all the supporting slaves responding, increasing the transfer efficiency.

8. A polling method compliant to Bluetooth protocol for increasing transfer efficiency, comprising:
-
a master sending a first polling packet in a first polling time slot; M slaves receiving the first polling packet; wherein the master and the M slaves belong to a Bluetooth piconet; and the M slaves sending M first responding packets respectively in M first responding time slots according to M responding orders of the M slaves; wherein the M first responding time slots are adjacent to each other, and a most preceding first responding time slot of the M first responding time slots is adjacent to the first polling time slot; wherein a Kth slave of the M slaves sends a Kth first responding packet of the M first responding packets in a Kth first responding slots of the M responding time slots according to a Kth responding order of the M responding orders; wherein a period length of each of the M first responding time slots and a period length of the first polling time slots are both equal to a cycle; wherein K and M both represent positive integers, and 2≦

14. A polling system compliant to Bluetooth protocol for increasing transfer efficiency, comprising:
-
a master, for sending a first polling packet; wherein the master sends the first polling packet in a first polling time slot; and M slaves, for sending M first responding packets in M first responding time slots, respectively, according to the first polling packet and M responding orders of the M slaves; wherein the M first responding time slots are adjacent to each other, and a most preceding first responding time slot of the M first responding time slots is adjacent to the first polling time slot; wherein a Kth slave of the M slaves sends a Kth first responding packet of the M first responding packets in a Kth first responding slots of the M responding time slots according to a Kth responding order of the M responding orders; wherein the master and the M slaves belong to a Bluetooth piconet; wherein K and M both represent positive integers, and 2≦
