The application discloses a data
interaction method and
system based on
Bluetooth communication, and relates to the technical field of communication, which comprises the following steps: real-time scanning of interference and load conditions of each channel through a multi-channel cooperative scheduling mechanism of a
Bluetooth device; constructing a channel
utilization rate evaluation model and dynamically selecting an optimal channel combination; receiving end adopts a
hybrid automatic repeat request mechanism to perform real-time checking on each
link data flow; performing
demand analysis and decision allocation and dynamically allocating resource units; judging whether interference exists in the
current channel; real-time statistics of end-to-end
delay of data packets from sending to receiving, and triggering a dynamic optimization process when the
delay exceeds a threshold; and sharing channel resources among access points through a cooperative
spatial multiplexing technology. Through the setting of a channel combination module, a
delay monitoring module and a resource sharing module, the delay of multi-device concurrent transmission is reduced, the channel resources are shared among access points, and the quality of
Bluetooth communication is improved.
