AI Technical Summary

Problems solved by technology

Although the theoretical transmission distance can reach up to 100 meters, in actual scenarios, limited by factors such as transmission power and wall barriers, the transmission range of consumer-grade Bluetooth wireless signals is very small, and the actual distance that can ensure stable transmission is often only a few meters or a dozen meters
This limits the data transmission distance between the application of the Bluetooth host and the Bluetooth device
[0003] The traditional method to extend the transmission distance includes increasing the transmission power and removing obstacles to make the scene more open, but increasing the transmission power will lead to increased power consumption and shortened device battery life; moreover, relevant national regulations also have restrictions on the transmission power (The 2.4GHz frequency band shall not exceed 100mW (milliwatts) or 20dBm (decibel milliwatts)), so it is impossible to increase the power infinitely

Embodiment 1

[0040] This embodiment provides a bluetooth device remote control system, such as figure 1 As shown, the Bluetooth device remote control system includes a host terminal 1 and a Bluetooth gateway 2; the host terminal 1 is used to communicate with an external Bluetooth device 3 through the Bluetooth gateway 2;

[0041] The host end includes a Bluetooth application program 101 , a virtual Bluetooth protocol stack 102 , a first network module 103 and a second Bluetooth module 104 , and the Bluetooth gateway 2 includes a second network module 201 and a first Bluetooth module 202 .

[0042] The bluetooth application program 101 is used to judge whether the external bluetooth device 3 is within the short-distance communication range, if so, then communicate with the external bluetooth device 3 through the second bluetooth module 104, if not, then communicate with the external bluetooth device 3 through the bluetooth gateway 2.

[0043] When the Bluetooth application 101 determines th...

Embodiment 2

[0079] This embodiment provides a remote control method for a Bluetooth device, and the remote control method for a Bluetooth device is implemented based on the remote control system for a Bluetooth device as in Embodiment 1. Such as image 3 As shown, the Bluetooth device remote control methods include:

[0080] Step 300, the Bluetooth application program judges whether the external Bluetooth device is within the short-distance communication range, if so, then execute step 301; if not, then execute step 302;

[0081] Step 301, the bluetooth application program communicates with the external bluetooth device through the second bluetooth module.

[0082] The second bluetooth module comprises bluetooth protocol stack API (application programming interface), bluetooth driver module and bluetooth hardware, and bluetooth transfers bluetooth protocol stack API to realize bluetooth device discovery process, device connection process, communication process (to external bluetooth devi...

Abstract

The invention discloses a bluetooth equipment remote control system and method. The bluetooth equipment remote control system comprises a host terminal and a bluetooth gateway. The host terminal comprises a bluetooth application program, a virtual bluetooth protocol stack and a first network module. The bluetooth gateway comprises a second network module and a first bluetooth module. The first network module is used for communicating with the second network module. The bluetooth application program is used for transmitting a bluetooth control command to the virtual bluetooth protocol stack. The virtual bluetooth protocol stack is used for transmitting the bluetooth control command to the first network module. The first network module is used for transmitting the bluetooth control command to the second network module. The second network module is used for calling the first bluetooth module to perform the bluetooth control command so that the first bluetooth module is enabled to communicate with external bluetooth equipment. According to the bluetooth equipment remote control system, the data transmission distance between the host terminal and the external bluetooth equipment is notlimited so that the range of application of the bluetooth equipment is wider.

Description

technical field [0001] The invention relates to the communication field, in particular to a bluetooth device remote control system and method. Background technique [0002] As a wireless communication method, Bluetooth can realize the communication between the Bluetooth host and the Bluetooth device. Bluetooth data is transmitted wirelessly between the Bluetooth host and the Bluetooth device, using the 2.4GHz (a frequency unit) working frequency band. Although the theoretical transmission distance can reach up to 100 meters, in actual scenarios, limited by factors such as transmission power and wall barriers, the transmission range of consumer-grade Bluetooth wireless signals is very small, and the actual distance that can ensure stable transmission is often only a few meters or a dozen meters. This limits the data transmission distance between the application of the Bluetooth host and the Bluetooth device. [0003] The traditional method to extend the transmission distanc...
