Bluetooth Transmission System

A Bluetooth transmission system is composed of at least a monitoring device and at least a mobile communication device. The monitoring device can detect and produce a biosignal, an environmental signal, and a broadcast signal, which are allocated with a universally unique identifier (UUID); further, the monitoring device has an information packet generation module that generates an information packet with the UUID, biosignal, environmental signal or broadcast signal, and then automatically sends the packet to a mobile communication device. In addition, when the mobile communication device receives information packet from different monitoring devices, it will decode the information packet, identify corresponding monitoring device through its UUID, and receive corresponding signal. Therefore, this invention can provide communication between at least a mobile communication device and several monitoring devices.
