Bluetooth data information transmission method and device

The invention discloses a Bluetooth data information transmission method and a device. The method comprises the following steps: receiving Bluetooth data information by using a first chip; under the condition that it is judged that the Bluetooth data information meets the preset condition, realizing communication connection of the first chip with an application processor so as to start the application processor, and the application processor is used for transmitting the Bluetooth data information. The method comprises the following steps: receiving Bluetooth data information by using a first chip; and judging the Bluetooth data information, and determining whether to start the application processor or not according to a judgment result. The application processor is started only when needed, and is not started when not needed, so that the workload of the application processor is reduced, and the standby time of the terminal is prolonged. And the Bluetooth data information are transmitted by using the applicati
