It is shown, the dynamic broadcast method of the bluetooth equipment, comprise the following steps：
Step S110：When the time span disconnected with intelligent terminal is the integral multiple of predetermined time period, it is determined that
Current communications time interval.
The intelligent terminal be with bluetooth equipment carry out data exchange terminal device, as smart mobile phone, tablet personal computer and
Palm PC etc..When intelligent terminal and bluetooth equipment passively disconnect, intelligent terminal reopens scan function.Meanwhile
The timer of bluetooth equipment starts, the time span that record disconnects with intelligent terminal.When described disconnected with intelligent terminal connects
When the time span connect is the integral multiple of predetermined time period, current communications time interval is redefined.
Step S120：The attribute information of itself is sent to intelligent terminal at intervals of the cycle with the current communications time of determination,
Untill being connected with the intelligent terminal.
When redefining to obtain current communications time interval, bluetooth equipment is with the current communications time at intervals of the cycle
The attribute information of itself is sent to intelligent terminal.Judge after preset time, whether bluetooth equipment is built again with intelligent terminal
Vertical connection, if it is not, the time span for then judging to disconnect with intelligent terminal whether be predetermined time period integral multiple.If
The time span disconnected with intelligent terminal is the integral multiple of predetermined time period, then redefines between current communications time
Every, the attribute information of itself is sent to intelligent terminal at intervals of the cycle with the current communications time of determination, until with the intelligence
Untill terminal connects.
The dynamic broadcast method of bluetooth equipment provided in an embodiment of the present invention, by with intelligent terminal disconnect when
