Bluetooth main circuit and Bluetooth sub-circuit in a multi-configuration personnel type Bluetooth device that can adaptively switch the operation mode according to the change of the data type of the received packet.

摘要

PROBLEM TO BE SOLVED: To adaptively adjust an operation mode of a Bluetooth sub-circuit in a multi-member Bluetooth device when the data type of a packet transmitted by the remote Bluetooth device changes. SOLUTION: In a multi-configuration personnel type Bluetooth device 100, while the Bluetooth subcircuits (second and third Bluetooth circuits 120 and 130) operate in the interception mode, the Bluetooth main circuit (first Bluetooth circuit 110) is a remote Bluetooth. Upon receiving the packet from the device, the Bluetooth subcircuit intercepts the packet from the remote Bluetooth device. When the data type of the packet from the remote bluetooth device changes, the bluetooth subcircuit switches from interception mode to indirect receive mode, receives the packet transfer from the remote bluetooth device received by the bluetooth main circuit, and receives the packet transfer from the remote bluetooth device. Does not intercept packets. [Selection diagram] Fig. 1
