Bluetooth wake-up method, system and device

In order to overcome the defects in the prior art, the invention provides a Bluetooth awakening method, system and device, and the method comprises the following steps: keeping communication between a Bluetooth module in a device to be awakened and an external awakening device, and enabling the Bluetooth module to receive an awakening signal sent by the awakening device; a control module in the to-be-awakened device sends an interrupt signal according to an intermediate signal sent by a preset pin of the Bluetooth module; and the control module takes the interrupt signal as interrupt input of the to-be-awakened device to awaken the to-be-awakened device. According to the method provided by the invention, different Bluetooth modules can be compatible, the same Bluetooth module and the same platform branch do not need to be customized differentially, the broadcast format of the wake-up device does not need to be considered, and the cost is reduced on the basis of ensuring that the applicability of the wake-up d
