F) judge whether other bluetooths BLE has data broadcasting to come out from equipment, if so, executing step G)；Otherwise, return step
A)；
G after) the BLE broadcast packet listened to is filtered, screens, classifies and is summarized, host computer or Internet of Things cloud platform are waited
Inquiry, return step A).
9. according to claim 8 led to using the bluetooth BLE communication device as described in claim 1 to 7 any one
Believe the method for control, which is characterized in that the step G) further comprise:
G1) to listen in the BLE broadcast packet do not meet setting format data filtering fall, reservation meet the setting format
Data；The BLE broadcast packet includes heart rate, amount of exercise, temperature, battery capacity and key value instantly；
G2 useful information) is filtered out according to data type；The useful information includes heart rate, amount of exercise and key value；
G3) according to data type and timestamp, data duplicate in the useful information is weeded out, final significant figure is obtained
According to, and the valid data are uploaded into the host computer or Internet of Things cloud platform.
10. according to claim 8 led to using the bluetooth BLE communication device as described in claim 1 to 7 any one
Believe control method, which is characterized in that the bluetooth BLE from equipment be bluetooth bracelet or the base station ibeacon bluetooth BLE.
