Service data transmission method and related equipment

The invention provides a service data transmission method and related equipment, which are applied to a mobile phone, and the method comprises the following steps: establishing a first Bluetooth logic channel with a first main control chip of wearable equipment and a second Bluetooth logic channel with a second main control chip of the wearable equipment, the first main control chip and the second main control chip are different in processing capacity and energy consumption; and according to the interaction channel corresponding to the service, sending the service data to the first main control chip through the first Bluetooth logic channel, or sending the service data to the second main control chip through the second Bluetooth logic channel. According to the application, the channel for the mobile phone to transmit the service data to the wearable device can be decided, the awakening frequency of the high-energy-consumption main control chip in the wearable device is reduced, and the endurance of the wearab
