and constructing the preset fingerprint database according to the position fingerprint and the position information of each target position in the plurality of target positions, wherein the position fingerprint of the target position is determined according to the signal intensity information of the target position.
7. A method of locating a bluetooth device, applied to a second bluetooth device, the method comprising:
the second Bluetooth device obtains a target signal sent by the third Bluetooth device to the first gateway, wherein the target signal comprises a low-order Media Access Control (MAC) address of the first Bluetooth device;
under the condition that the first Bluetooth device is in a state of being not discoverable, the second Bluetooth device calls the first Bluetooth device according to the low-order MAC address to obtain a call result;
and the second Bluetooth device sends the call result to the server through a second gateway.
8. A positioning apparatus for a bluetooth device, the apparatus comprising:
the first acquisition module is used for acquiring a call result of the second Bluetooth device by the server, wherein the call result is a result of the second Bluetooth device calling the first Bluetooth device based on the low-order Media Access Control (MAC) address;
and the determining module is used for determining the position information of the first Bluetooth device according to the calling result by the server.
9. A positioning apparatus for a bluetooth device, the apparatus comprising:
the second acquisition module is used for acquiring a target signal sent by the third Bluetooth device to the first gateway by the second Bluetooth device, wherein the target signal comprises a low-order Media Access Control (MAC) address of the first Bluetooth device;
the calling module is used for calling the first Bluetooth device according to the low-order MAC address to obtain a calling result when the first Bluetooth device is in a state that the first Bluetooth device cannot be found;
and the sending module is used for sending the call result to the server through the second gateway by the second Bluetooth device.
10. An electronic device comprising a processor, a memory and a program or instruction stored on the memory and executable on the processor, which when executed by the processor, implements the steps of the method of locating a bluetooth device according to any of claims 1-7 or 8.
11. A readable storage medium, characterized in that the readable storage medium has stored thereon a program or instructions which, when executed by a processor, implement the steps of the method of positioning a bluetooth device according to any of claims 1-7 or 8.
