Abstract
A BLE-based positioning method is applied to a terminal device, and includes: calculating a change rule of the RSSI value when a received signal strength indication (RSSI) value obtained by parsing a received signal of a target BLE slave device is less than a predetermined threshold; and generating prompt information used for prompting a moving direction of the terminal device according to the change rule of the RSSI value until the RSSI value is greater than or equal to the predetermined threshold.
