Title: POSITIONING METHOD AND APPARATUS BASED ON BLUETOOTH (BLE)
Abstract:
The present invention relates to the field of wireless communications. Disclosed are a positioning method and apparatus based on Bluetooth (BLE). In the present invention, the positioning method based on Bluetooth (BLE) is applied to a terminal device, and comprises: when an RSSI value parsed from the received signal of a target BLE slave device is less than a pre-set threshold value, calculating a change rule of the RSSI value; and generating prompt information for prompting a movement 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 pre-set threshold value. Also disclosed is a positioning apparatus based on Bluetooth (BLE). Compared with the prior art, the present invention can quickly find the position of a target BLE slave device, thereby greatly reducing the time for searching for the target BLE slave device. In addition, quick positioning of a target BLE slave device can be implemented without deploying an iBeacon or Bluetooth AP indoors, and there is no need for a complex data processing architecture, thereby reducing hardware costs.
