Abstract
Disclosed is a method of connecting a plurality of apparatuses using low-power Bluetooth. A plurality of slave apparatuses are connected to a master apparatus, and various signals or times are assigned to a time schedule table. In other words, a scan period, a window scanning time, a registration period, a registration signal, a general period, and a general signal are assigned to the time schedule table without being assigned to the same position of the time schedule table. More specifically, the slave apparatuses are connected to the master apparatus through a scheme of preventing start time points to which the signals are assigned from being assigned to the same position.
Claims8
A method of connecting a plurality of apparatuses using low-power Bluetooth, the method comprising:
- a time schedule table forming step, carried out by a master apparatus, of setting a unit time for maintaining a connection event in which the master apparatus is connected to a slave apparatus, setting a registration period as a predetermined multiple of the unit time, setting a general period as a predetermined multiple of the registration period, performing a modular operation on a time based on the general period and performing a modular operation on the time based on the registration period to arrange the time by grouping the time;
- a scan step, carried out by the master apparatus, of assigning, to a time schedule table, a window scanning time in which the master apparatus receives an advertisement packet with a scan period, which is set as a predetermined multiple of the unit time, to receive the advertisement packet transmitted from the slave apparatus;
- a connection request step, carried out by the master apparatus, of transmitting a connection packet to the slave apparatus if the master apparatus receives the advertisement packet during the window scanning time to connect the master apparatus to the slave apparatus, which is detected as a connectable one;
- a registration connection step, carried out by the master apparatus, of transceiving data for registration with the registration period only during a predetermined group to allow the slave apparatus, which is detected to be connectable to the master apparatus, to be registration-connected to the master apparatus for data transmission and reception;
- and
- a general connection step, carried out by the master apparatus, of repeatedly transceiving data for general connection during a group other than a group during which at least the data for registration is transceived with the general period, to switch a connection state to a general connection in which the master apparatus and the slave apparatus, which are registration-connected to each other, transceive data with each other with a predetermined period.
