1. A distance measurement and alarm method, comprising:
- directly sending, by a sending terminal, pairing request information to a receiving terminal, wherein the pairing request information is configured to establish a direct connection between the sending terminal and the receiving terminal;
after the sending terminal is paired with the receiving terminal, calculating, by the sending terminal, a current distance to the receiving terminal; and
comparing, by the sending terminal, the current distance with a preset distance threshold, and if the current distance exceeds the distance threshold, displaying distance prompt information on the sending terminal.
