Abstract
A terminal device includes or connects to an external Hall device. The terminal device enters a to-be-connected state based on a Hall event generated by the Hall device, where terminal device is configured for connection to an externally device using a wireless communication protocol. The terminal device sends a trigger signal to enable the externally device to enter the to-be-connected state based on the trigger signal, and establishes the connection to the externally device using the wireless communication protocol.
