Example Embodiment

[0025] The remote control method based on the Bluetooth broadcast packet includes the following steps: including the code matching method, the data transmission method and the data processing method in order. The remote control after the code connection can transmit data to the host, and the host performs the data processing after receiving the data. A series of data processing.

[0026] Step 1: Use the remote control for the first time, and use the code matching method based on the Bluetooth broadcast package to pair the remote control and the Bluetooth host; the specific process of the code matching method is:

[0027] 1.1 The remote control randomly generates a device ID and broadcasts it for a period of time in the form of a Bluetooth broadcast packet. The broadcast packet data is packaged and sent according to the packet format of Bluetooth ADV_NON_CONN_IND;

[0028] 1.2 After the host receives the Bluetooth broadcast packet data reported by the receiving device, it judges wheth...

Abstract

The invention relates to a remote control method based on a bluetooth broadcast packet, which comprises the following steps: 1)using a remote controller at first time, employing a code matching method based on the bluetooth broadcast packet to match the remote controller with a bluetooth host terminal; 2) transmitting data to the host terminal by the remote controller, packaging data according to a format of bluetooth ADV_NON_CONN_IND packet, wherein each packet is transmitted for several times repeatedly for avoiding data packet dropout; and 3) processing data, and respectively performing corresponded treatment on different types of data to control the host terminal. According to the invention, the method has the advantages of simple operation, low cost and rapid matching, and can realize one-to-many control under special application scenes such as production line.

Description

technical field [0001] The invention relates to a remote control method realized based on bluetooth broadcast packets. Background technique [0002] Bluetooth (Bluetooth) is a new type, open, low-cost, short-distance wireless connection technology, which can replace short-distance cables and realize wireless transmission of voice and data. This effective and cheap wireless connection technology can easily connect computers and portable devices, PDAs, mobile phones, camera phones, printers, digital cameras, headsets, keyboards and even computer mice to achieve wireless transmission of multimedia information. Within its reachable range, various information-based mobile portable devices can realize seamless resource sharing. Bluetooth supports point-to-point and point-to-multipoint communication. In order to realize point-to-multipoint communication, data is sent in the form of broadcast, so that receivers within a certain range can receive the data. [0003] Bluetooth remote...
