Circuit Description Battery (DC 3.7V) provides energy for the Bluetooth chip (AC6956A); Crystal oscillator (24MHz) pr ovides the clock signal for the Bluetooth chip. Bluetooth signals get through a matching circuit, an d then transmitted to the space through the antenna (2402-2480MHz). When the product is connected, the product can in two-way communication with other Bluetoot h Devices, and then the device’s Bluetooth module sends Bluetooth signals into space, the produ ct receives the Bluetooth signal through an antenna, transmission to the Bluetooth chip via matc hing circuit.
