1. A synchronization control method, applied to a master device, comprising: a computing operation and a transmission operation; wherein
the computing operation comprises:
setting a reference time for a plurality of slave devices wirelessly connected to the master device;
for each of the plurality of slave devices, determining a target count value K of a connection event and an offset time of a respective slave device; wherein an offset time of a slave device refers to a time difference between the reference time and a start time of a Kth connection event of the slave device;
the transmission operation comprises:
for each of the plurality of slave devices, transmitting the target count value K of the connection event and the offset time to a respective slave device, so that the respective slave device performs control based on the target count value K of the connection event and the offset time, so as to perform a task at the reference time.
