SERVICE DATA TRANSMISSION METHOD AND RELATED DEVICE

The present application provides a service data transmission method and a related device, which are applied to a mobile phone. The method comprises: establishing a first Bluetooth logical channel with a first main control chip of a wearable device and a second Bluetooth logical channel with a second main control chip of the wearable device, the processing capability and energy consumption of the first main control chip and the second main control chip being different; and according to an interaction channel corresponding to a service, sending service data to the first main control chip by means of the first Bluetooth logical channel or sending the service data to the second main control chip by means of the second Bluetooth logical channel. According to the present application, the mobile phone can be decided to transmit the service data to the channel of the wearable device, so that the wake-up frequency of the high-energy-consumption main control chip in the wearable device is reduced, and the endurance of
