Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the bluetooth connection process is as follows: scan the bluetooth device of the laser rangefinder, the bluetooth device of the laser bluetooth rangefinder will return a device list, and the device list will transfer the device information to the connect method of the program for connection, and judge whether the device is connected successfully , if the connection is successful, the App will display a successful connection with the device. If the connection fails, update the interface and continue to scan the device.

[0020] The process when the bluetooth of the present invention transmits data is as figure 1 As shown, the following steps are included:

[0021] Step 1: Run the App software on the Android operating system and scan the Bluetooth device of the laser rangefinder; the laser rangefinder communicates with the A...

Abstract

The invention discloses a laser range finder bluetooth communication method based on an Android operating system. The method comprises steps as follows: scanning: laser range finder bluetooth equipment is scanned; connection: when enabling of the laser range finder Bluetooth equipment is scanned, attribute information is acquired, and connection is established; communication: hexadecimal request data is sent by an App, and the laser range finder Bluetooth equipment and a preset mobile terminal transmit data mutually. The App requests single-measurement hexadecimal request data, the equipment is in a single-measurement state, so that data is automatically called back and sent to the App after equipment measurement is finished each time, power consumption of the bluetooth equipment is reduced, the App is more stable, and user experience is better.

Description

technical field [0001] The invention belongs to the technical field of wireless communication and relates to the application of an Android operating system, in particular to a Bluetooth communication method for a laser range finder based on the Android operating system. Background technique [0002] At present, with the popularization of smart devices, the smart operating system has been greatly developed. Android system is an open source operating system launched by Google, which is widely used as the operating system of mobile terminals, tablet computers and smart TVs. middle. BLE is the abbreviation of Bluetooth Low Energy, also known as Bluetooth 4.0. Compared with the original Bluetooth technology, it is characterized by low power consumption, low delay, and long effective connection distance. [0003] The laser range finder is an instrument that uses a certain parameter of the modulated laser to accurately measure the distance of the target. The pulsed laser rangefi...
